8Fun BBS02 Review - $800
ฝัง
- เผยแพร่เมื่อ 5 ก.ย. 2024
- The 8Fun BBS02 is one of the only mid-drive electric bike conversion kits around, 8Fun is an established brand. Offers both pedal assist and throttle mode configurations, great LCD screen with lots of options. Not sophisticated enough to sense when shifting gears and let up, may wear chain and cassette faster. Keeps weight low and center on bike, makes fixing wheels and flats easier than hub motors.

FANTASTIC review (as usual) covering so much info about the Bafang BBS02.
I am sure lot of people picked Bafang mid-drives after watched some good videos like this one. Thanks for inspiring many new eBike riders, your channel is really amazing!! You rock =]
Bruno
Mate you've got a real talent for filming one handed on the move, great vid.
Ha! Thanks Bertie, I've been practicing it for a while now and getting the hang of things alright. Just got a new camera holder thing that should make the video smoother. I've only crashed once so far... always wearing that helmet :P
Again: Mate you've got a real talent for filming one handed on the move, great vid. AND a sound withoud wind noise. Good job.
@@ElectricBikeReview Gimbals make all the difference but it helps to actually know what you are doing what you seem to do. Great job
This is some of the best one-hand video work I've ever seen. Excellently informative visuals, great job.
Hey! Thanks Frank, that means a lot to me. I ry to pack a lot in and do a great job as a one person team here. I'm always struggling between doing more video editing and going high quality there vs. going for volume and hitting more bikes. I try to strike a good balance and I'm glad you enjoyed my work here :D
Just hooked mine up and uploaded a video of it and I've got to say...more people need these. Totally worth the money!
Mate, great review. Thank you. I think I’m sold. I feel like 750w is the good zone. I don’t want to pedal haha. The 250 I rode was too weak.
Love my bafang 750w motor! Fitted it to a Marin B17 down hill bike, 54volt 10ah lifepo4 battery, current gearing get 45mph+, 0 to 25mph under 2 seconds! Average 20 miles range with a mix of road and off road riding. About to fit a Nuvinci internal geared hub which should really work well with the motor. Great review and web site by the way, good source of information, thanks.
That's awesome! Thanks for sharing your specs, I really like these BBS02 kits and being able to use your own battery for extra power, speed and range is great. The Nuvinci N360 is pretty good for mid-drive setups, hopefully it's an easy install. Thanks for the props on my website, glad it helped you out :)
Court. Please do more reviews of this drive. I have one on order, but I love to see anything to do with it. Also, you are the reason I'm getting one. Thanks.
Cool! Glad the review helped you Ray, I will keep an eye out and try to get more footage for you. This video was shot in New York and I'm in Colorado right now but will be at a trade show later in September where I might see the 8Fun Bafang stuff again :) once you get yours and hook it up, share a picture and your own thoughts in the 8Fun forum: electricbikereview.com/community/forums/8fun/
Electric Bike Review
Will do Court. And if you ever find yourself in Jersey (or NYC for that matter), and you need something. You let me know.
Ray Mosier Thanks Ray, that's awesome! If you'd like to connect, shoot me an email through the Contact form on EBR or say hi in the forums. I've met a couple of other people that way and it's nice to have friends when traveling. I'm sure I'll be back up your way sometime next year.
5:12 you can program these anyway you like. There are up to 9 levels of assist and you can also turn on thumb throttle only mode. Some of these can be done only via the programming cable and others through the head unit alone.
Hi! It's a trully joy to see your review and tips. Super clean speach and filming. Thank uou so much. :)
paulo guimarães Thanks Paulo! I do my best to have fun, be quick and also complete. Your word of support mean a lot :D
1. The item in the battery bag on the recumbent bike is the charger. The motor controller is built into the unit itself.
2. The controller can be custom programmed. For instance I have the the zero PAS setting set at throttle only. letriccycles.com can sell you a motor with custom programming.
3. Pedaling backwards or slight tap on the ebrakes cuts the motor for shifting.
4. The motor is very quiet. Compare the sound in this video to those of the Bosch bikes.
Great tips, thanks man!
Thanks for another informative review. I am currently having Matt Hughs from EMPowered cycles in Castro Valley, CA install a Bafang BBHD with 52V/13.5AH battery on my HP Velotechnik Scorpion FS 26 recumbent trike. This will have derailleur & brake motor cutoff. I had a stroke and had to switch to a recumbent cycle as a result. This should be awesome for me. The fully suspended trike should be able to do light off-roading too.
Hi @tarheelsrock53 glad you enjoyed the video... I've been excited to get it out for a while too. Actually shot it a week ago but had to process the footage and write the review. I've got ~20 more bikes in the queue that should go up once I've finished the road trip (currently in Montreal Canada).
ElectricBikeReview.com That motor is just insanely overpriced. Electric motors are simple and cheap to manufacture and $750 for just the motor and a freewheel is absurd. With a couple of brackets you could pick an old electric scooter out of the trash and use it's motor and controller and buy a freewheel for the BB at sickbikeparts. If the price of batteries falls (and that's unlikely given the collapse of oil prices), that is what I will do... I'll build my own. The kit should be maybe $100 more than the battery and controller, not $750. These aren't industrial high performance motors, they are consumer grade non field serviceable (all industrial grade motors are field serviceable. Field serviceability is one of the hallmarks of being industrial grade), they just aren't worth the kind of money they are asking. When you add up all the costs, you can just buy a motorcycle if practical transportation is your goal. If cycling is just a hobby, what's the point? Pedaling is the hobby.
ElectricBikeReview.com Hey EBR, after building this set for my dad on a mountain bike. I feel
indifferent with you about praising this motor kit, I would give this
kit a bad review.
The main problem with it is that it has a
terrible chainline alignment problem. The motor on the driveside has a
large internal cog which blatantly sticks way out to the right side of
the bike. This changes the Q factor of your right leg tremendously
(about 2cm) and you will be fine on the small gear in the back (for
speed) but as soon as you start climbing up the gears, the
misalignment/crosschaining is so prominent, the chain wants to jump from
the crank to the frame.
I try to counter the problem by having a
slacker chain but the offset is just too great that basically, bigger
gears should not/cannot be used. The chain simply comes off at the
front.
another problem I have with this kit is not very serious
but still upsets me. The mounting system for the motor relies on a
clamping system on either side of the BB onto the frame with steel teeth
with 40nm of force. It does not utilize the threads of a BSA bottom
bracket. This means you best use this motor on a frame you could care
less about because it damages the face of the BB after installation and
use. I would say the BB face surface would not be reusable, not even
with facing and chasing
to me, this kit is a testament to Chinese
engineering and blatantly ignores many fundamental bike mechanics. my
recommendation is DO NOT BUY THIS KIT, it is a compromise of
price/product. buy a bike with a frame made for the motor so you wont
have to worry about chainline and frame damage. Pedalling with one leg
way out there is not good for your hips/knees either.
tarstarkusz I have actually built my own mid motor system entriely out of a free recycled 500 watt mobility scooter that was old and in the trash. Used the same controller and throttle and even the built in 24 volt battery charger and battery guage, horn and key! Welding up a BMX single speed freewheel sprocket that ran on a small chain to a custom made left hand sprocket was tricky but It worked. The worm drive reduction gear used on scooters was noisy and cumbersome. But yeah, if money is a real problem and you have skills, all these things can be build DIY from upcycled parts being thrown away everyday! Also cheap are 500 watt 24volt 12 inch scooter rear hub motors, which can be pushed to 48volts. Normally mounted to a 16" tire. Makes a good pancake motor to cut down and build your own StokeMonkey style in line chain drive system. Might cost 50 bucks for an old scooter motor.
+Mike Brink I agree, they are just way too expensive to be anything more than a toy for someone with lots of cash to throw away. Mass production may be able to help and maybe Elon Musk's giga-factory will help lower the costs of the battery. The battery really is the biggest problem with an e-bike. Most can't even do 20miles in real world conditions unless you are using only a minor pedal assist. I really don't know if the market is big enough for mass manufacturing though, especially in the US. Almost everyone owns a car and almost everyone who bikes also owns a car and bike for pleasure.
Extremely informative review. Thanks so much for taking the time to do this. This sold me, will be purchasing !
Awesome, glad it helped you! I've been reviewing for a couple of years now, always trying to get more info and do better shots, audio etc. You can see the full review for this and other kits back at the site (linked in the description) or for low speed ebikes at: electricbikereview.com/
Great...will be referring your site to a few colleagues!
Anon Existent Nice, hope it helps them out as well! Drop in and comment anytime, the community forums can also be useful :)
Your informative review swayed me towards fitting a NuVinchi N360 hub on my Surly troll build with a 350w BBS O1 motor kit, It rides great CVT gears are so smooth.
Have to say tho the wireing harness and cableing on that demo bike are a mess it looks like kit was thrown on bike as fast as possible.
Hey Marshall, sounds like a sweet setup you've made! Yeah, the bike in the video literally was thrown together. The guys at Long Island Electric Bikes were testing the BBS01 and BBS02 on several different bikes so appearance was less of a factor and they stayed out of the way enough to be safe. Would love to see some pictures or video of your setup! Feel free to post in the forums: electricbikereview.com/community/forums/8fun/
Excellent review! The only thing missing was mentioning that the throttle input is an excellent means for adding punch when climbing steep hills in low gearing when the power-assist level 3 begins to fade. I agree wholeheartedly that they absolutely should have made the assist 0 a throttle-only mode.
This video is very helpful to me because you showed me that you can ride it without pedaling
FYI, you can program the BaFang 750 to work on PAS 0 if you like. There is an App you can download and a cable with a USB port on one side and the other to the bike screen. Plus you can order the gear change motor cut off so there is no gear mashing.
Would love to see BBS02 comparison with other kits like the Bewo, TSDZ-1 or Xofo kits
Nice crisp video, just a slight rectification. There are newer models now “Bafang Ultra” That has All the Sensors included. And on the Bbshd Bbs02 you’ll have the cadence/speed/brake sensors and you can add the gear shift sensor for about $20 bucks. As for a solution for the torque sensor you get the PAS where you can choose for up to 9 pedal power assist
I've had one of these on order for over 2 weeks now from China and it still hasn't shipped! I swear I have watched this video 10 times while waiting, its gonna be so good when I finally get my hands on it. I got it for the equivalent of $700 but you really get what you pay for on the service side with these wait times for a 'sample' unit straight from the factory. It is alibaba though so I won't lose any money if it never turns up, but I really hope it works out and I can be cruising with this kit soon. Once I saw mid drives I knew I couldn't settle for a hub motor.
Oh man! I hope it ships soon for you... I didn't realize Alibaba offered that protection. Cool! Would love to hear how it works for you and what it's like to install. Feel free to share in the forums electricbikereview.com/community/forums/8fun/
Electric Bike Review Thanks for your reply, I am hoping it will work out and I will get the kit in the next 10 days or so.
I ordered the 350 watt Bafang bbs02 by the way due to lots of bad reports about the unresponsiveness of the pedal assist on the 01 model. I chose to go with that over the 750 mainly because I want handling that will be plausibly legal with the 250 watt EU limit as I want to use it partly for commuting and city use. However, I am putting it on an old Dawes Chilliwack fixed fork mountain bike which has seen plenty of crazy trail action all over the UK, so I am hoping to get some good off road experience on it with the kit on steep downhill trails come next summer. I would love to contribute to your forum once I have had a few weeks and months of experience with this thing, because I have found a relatively small amount of information about these units in the run up to buying one, particularly any comments on the power and speed when going up hills, especially throttle only and especially on the 350 watt unit. I also want to know whether it is comfortable or desirable to switch off the system and use pedal power alone so I can get my daily exercise.
Anyway, I will do my best to contribute to the sum total of knowledge about this product on your forum when I have tested it extensively.
+Electric Bike Review Oh btw its Aliexpress, which is sort of the more ebay-esque format Alibaba, which doesn't require bulk orders and is intended for consumers rather than suppliers. I regret to say I don't know exactly how the policy works, but it does say in plain english on the login screen that if no product or an incorrect product turns up, you are entitled to a complete refund, and payment is only released when you acknowledge receipt of the package on the site.
veryveryintense Interesting, thanks for the clarification about Aliexpress. I just visited their site for the first time www.aliexpress.com/ pretty neat. Yeah, I'm excited for you and looking forward to feedback on the unit. I also heard some things about motor issues but the ones I test rode with were great. my time is usually very limited so I realize my reviews lack some of the full story and it's nice to get it from actual real-world owners :)
ElectricBikeReview.com I just received the kit today but they sent the bbs-01 :(. No way am I gonna wait another month (and the rest) to get a new one, so I hope I can get some kind of part refund and keep the goods. Also my battery is being mailed separately so I will have to wait a week to use it!
I've worked with the Bosch and shimano steps motors, and they dont have all the sensors. they simply detect the torque coming in thru the cranks, and then just add a multiplier to it. no brake sensing etc, doesnt need it.
its so intuitive, I could do mad wheelies straight away with it
Another great review, Court!
Your Chinese is pretty darn good!
The Chinese consider the number "8" to mean prosperity or wealth. Phonetically, it sounds like "bot" rhyming with robot. If one were to eliminate the "t" sound at the end, then you get the "bah" sound. Putting it all together you will get that "bah fong" sound.
All right, enough of the Chinese.
At 4:50 into the video, I agree with your rant: Bafang needs to have a throttle-only mode that is separated from PAS. But they should still keep the throttle mode available with PAS. There are times when I'm on, say level 2, and just need a tad bit of help but not as much as level 3.
It would be cool too if they could update their firmware so that the system would back off on the power during shifts.
Thanks again!
Awesome, thanks for the feedback on how 8 is pronounced and also the significance of it :D
It's just nice to be able to choose when and how to use a throttle. Of course it would be great if it also backed off during shifting but that might also add complexity to the system... it would have to somehow connect to the shifting mechanism or something. Any ideas on how that could work without getting too complicated?
Electric Bike Review I have no idea how that would be done. I guess only Haibike has that part figured out. I noticed that the iZip E3 Peak doesn't back off on the power during shifts either.
Maybe Haibike/Bosch wanted to keep that proprietary to their bikes and not share it with the iZip product line, even though iZip and Haibike belong to Currie Tech.
***** Yeah... it must be an electrical signal or something when you activate the shifter. I'll ask the next time I'm near some of these bikes with a knowledgeable engineer. Great technology :)
That's a really good video. I appreciate that. I want to turn my mountain bike into a hunting ebike. But my only question since you are very good at covering all the things. Is does it breakdown much? I am going to be 10 15 20 miles into the mountains. I don't want it to break when I'm out there and I have my deer or elk. I'll never make it back.
I have had this model for 2 years and reckon its pretty solid. The dumb name didnt inspire confidence, but its actually a good setup, especially that it uses the bike gears unlike a wheel hub one.
Id also recommend the 8Fun setups.
Cool - that was the answer I was hoping for ! Thanks for your help. Josh
Sure, glad to help ;)
They also do a motor that detects the gears & when you change, you can also buy the sensor that does the same thing, I think you need to read up a bit more on what the BBS01/BBS02 Mid Drive motor kits do.
The Nuvinci N360 haven't designed for 750W mid-drive, but maximum 250W. The Nuvinci N171 is a better gear-hub to do that. You can check this point on the N360 specification...
Interesting, I didn't realize they had two products. I'll keep an eye out for the NuVinci N171 is it still in development? As far as rugged internally geared hubs go, the Rohloff Speedhub seems pretty good but isn't a CVT like NuVinci.
Electric Bike Review The N171 is the old version of NuVinci hub. It's difficult to find/buy one...
Stéphane Rapin Interesting, thanks Stéphane :)
Great review as are all of Court's.
I want to clear up a couple of either misconceptions or things that changed since 2014.
Price is now a lot less than $1500. I just bought one from www.empoweredcycles.com for $1100, motor + 17.5 Ah (about 800 watt-hour) battery. Would have been about $1000 with a 13.5 Ah battery.
The big thing to mention is that you can get a bafang gear sensor for $50. The "gear mashing" Court mentioned at the 8:20 mark is not an issue at all with this sensor. The motor cuts out when you hit the shift lever, even if you keep pedalling, so shifting is smooth with this sensor added.
I have a trek 8.6 ds hybrid with this kit. I love it. Top speed is easily 28 mph on the flat, I can cruise at over 20 in low assist, with a range of more than 40 miles (after a 40 mile ride I still had about 1/4 charge left). Range would be a bit less if you put it at high assist the whole time, I haven't tested that yet. It also climbs great, I have a 46 chainring and an 11-36 in the back. In 46/36 granny I can readily go up over 20% gradient.
I don't really notice any lack of smoothness with the cadence sensor. I've test ridden a Kalkhoff with the Bosch system and this feels just as nice to me. For a lot less $
Richard King thanks for the info mate
lunacycle nowadays has a gearshift sensor to mitigate shifting issues as well as universal brake sensors that even work with hydros. just a tidbit for those who found this late
Awesome video! Awesome bike! So tough looking. Love these aftermarket mid-drive kits! Looking to install a BBSHD on my voltbike Mariner this year!
You forgot to mention that on this kind of bike it must be amazing if we talk about swiching gear, no gear mashing, just smooth and powerfull acceleration :) But it must be strange pushing throttle + swiching gears in the same time though
That's very true, this bike doesn't have shift sensing technology built in so the chain and sprockets can mash together when shifting as you accelerate. I thought I touched on it a bit in the video and I definitely wrote about it in the full review) but I'll try to call it out more in the future :)
Here's a quote from the review "Compared with purpose built centerdrive systems this one doesn’t have the ability to sense when you shift gears so that could lead to some grinding and wear the chain and cassette down faster…" and the link: electricbikereview.com/8fun/bbs02/ thanks again for sharing Ladislav, I appreciate your feedback and am always trying to get better at this.
Good video - looking for a 8Fun but a U.S. distributor, who asked that I not disclose, says that there are issues on getting these drives. The distribution is messed up. This drive is the most quiet of all.
Thanks, I heard something similar... that the 750 watt BBS02 version had an issue or something and that it was being fixed. The unit I rode here worked very well and I also like the 350 watt BBS01 version which I think is more readily available: electricbikereview.com/8fun/bbs01/
Electric Bike Review I stated "distribution" and not a problem with the product itself.
Bobcatt22 Thanks, I may not be remembering correctly or may have gotten confused between distribution and an actual design change but I heard something similar about availability being limited.
Good video im pretty positive the bafang kits are only slightly behind the bosch ones. Bafang however will probably update the kits next year as they are shipping the 350w & 750w kits right now and we are going to see better kits but for the moment the 01 and 02 should be fine they seem to be a lot better than those front and rear kits.
It's great to see another quality mid-drive system for sure and I was impressed with the 8Fun quality given the much lower price and self-install option. Maybe we'll see something this year at Interbike? I'll definitely review it if so :)
Electric Bike Review
Possibly i hope they make new kits thats for sure.
If you just lightly touch brake levers they do not brake but act as clutch for changing gears. It shows when motor is disengaged on the screen supplied (small circle). Use the the brakes as clutch I have built a few of these bikes there is also an accessory that can be applied that senses gear changing but why bother just lightly touch brake lever and use as clutch. I think thats the way they actually want you to use it but they don't supply great instructions. It's a learning process but once you remember when changing gear no more crunching at the gears.
Awesome video mate - after watching this, I've bought the kit
its nice review but we didn't get most important information from it:
What is it top speed in some normal conditions?
How many kilometers we can drive with this kit on full speed before we need to recharge it?
Thanks Nemanja, sometimes I've got limited time or don't have the correct information about price, range and speed so I put that back at the website in the full writeup (linked in the description above). This also makes it easier to update over time as things change: electricbikereview.com/8fun/bbs02/
Electric Bike Review ohh sorry my mistake somehow I missed website. Really nicely summed information. Thank you and good job! For someone who want to get into eBike world your website is a good guide.
Nemanja Bekric No worries! Glad it helped you out. I'm working on some new tools to make the site even more useful but the videos will still be made and posted here with each new review :)
Is there a downside to putting this on a. Single gear bike?
Is this safe to use ?
i only worry about the lithium battery
is the battery pack sensitive to explode ?
holy crap ive been waiting for this review from you for a while!
Hi, do you know which type of battery I can use on this model and were I can get this? I'm only going to cycle short distances, so I don't need any large or expensive models. Thanks! :D
So incorporating a nuvinci hub eliminates the need for a rear cassette and it acts like an auto transmission? Does using a nuvinci hub make it so you're less likely to break a chain due to the high torque motor? IOW that fancy hub works 'in sync' with the motor and it instinctively knows which gear will make the motor happy?
If all that is true then I def want a mid drive. Thanks
Two things i'm interested in with e-bikes- Top speed and Range.
Hi. I like your video 😀! I would like to ask, after 6 years, are you still using the bicycle with this motor? Did you have any problems with the motor or with the battery?
Another great video review and discussion thread here. It's exciting to hear a 1000w motor and better controller is coming out - but *when* is the question! I'm wanting to install it on a fatbike too. Also, for those who have successfully installed it, what top speeds are you getting on flat ground, throttle only?
Thank you for posting, very helpful.
Sure thing, glad you enjoyed it ;)
15k on my bbshd motor.... still going strong
Hello 👍 ,, you can change the pin (motor) that enters the frame of the bottom bracket,!?
Let me explain,. I took the 100mm but, Pultroppo with the dissosamento chain crown house we are not there. He strains too much arrived at the 9 speed, from 10-11 goes hard and eats the iron.
Since I have a 148×12 mtb wagon. No more margin even with picnic crown that I recovered 5mm .. Nothing! It doesn't work. So I would like to try on my old 26 rockrider 5.2 mtb
Che a
The one thing that bothers me is no chain guard at the peddles
I thought all their kits are street legal from the 250w to 1000w has the speed is governed either with the control box on older models or internally in the motor on the newer models.
Brother I'm impressed! Does this sell in Canada? Being an older mountain biker, my legs ain't young anymore. This would be an advantage riding say up the Niagara Escarpment where its a long hill. What's the price if I could ask?
Best bang for your buck,nice componet setup
Agree, if I was going to build a conversion this would be the kit I'd go with (or maybe the FlyKly for city riding, I like the regen system they made).
Cool kit! 10:19 were you doing braking and accelerating noises? Haha that's awesome.
Hey Christophe, I think that might have been the sound of the chain tubes rattling against the long chain. I was also using the brakes however and there was a rear rack with panniers that could have been rattling around as well. Maybe it was just the different camera angle picking up the noise. Were you concerned about that being the motor or something?
No, I just pictured myself riding it and doing car noises with my mouth haha :)
Christophe L Ha! That's awesome...
I like a separate mid-drive system connected to the disc brake side.
***** Interesting, I haven't seen that a lot, could you provide an example so I can check it out?
***** I think I found one! electricbikereview.com/izip/express/
Just what I'm looking for as I've already got a quality bike but unfourtunately its ilegal here in the UK we can only do 250W. I was looking at Xion hub motors that peak at 1000W but only have 250W on the label to keep the law happy. We also cant go over 15mph before power cuts out.. frustrating really!
Yeah... the law in the UK is tough (unless you use your license and do speed pedelec). At least you've got a bunch of good Bosch drive ebikes. The centerdrive workse pretty well even on the 250 watt version :)
Typical pussy European laws limiting speed at 25km/h. I experience the same issue.
Take my advice and just get a bafang 250w mid drive motor you can go upto 22 mph with the thing plenty enough for anyone in the UK IMHO until our laws are updated with ebikes the laws have not picked them up properly yet.
N Its just a way of releasing liability for everyone but the rider so...ride whatever you want and...watch for cops! Just like any vehicle. You fudge a bit.
Get a control unit that lets you have a switch for switching between 25kmh and unlimited. If someone questions you, just flip the switch and say youve got strong legs.
Hi folks! I am hesitating between to buy an Bafang 750w mid-motor kit, and find an entry level mountain bike like Specialized, rocky mountain or Norco, or to buy a NCM Moscow plus ebike. For the same ending price I am not sure of the NCM bike quality?
thanks for the video mate, I just have a question, why the battery package is that huge? I've seen other batteries but they are smaller. If you can give me some tips, thanks
Thanks for the review. I was wondering why a 1000 watt unit is not available? I thought the law was no faster than 20 mph and no more than a 1000 watt motor. Or, is it a 1000 watt motor is just too powerful for the bikes drive system?
Great question, the law in the United States is 750 watts or less and 20mph unassisted with throttle or that same amount of power (that would get a 170 lb rider to 20mph) but open to higher speeds if the rider is pedaling along (this is known as speed pedelec) I've listed some of those reviews here: electricbikereview.com/tag/speed/
ElectricBikeReview.com This kit could be the answer to my mountain problems.
nebula722 Yeah, looks like you found this on your own! I just finished recommending it to you in the other comments you left :)
It offers several assist levels (I think you can set it from 3 to 8 and it just divides the levels into smaller increments of power output). I believe the throttle also offers variable output so you could twist it just a tad to get less power and really twist it for more if you need.
ElectricBikeReview.com
I think the 8Fun is the one I will install. Thanks
nebula722 Sounds good! I've heard a bit about the BBS02 having some troubles late last year, might call Long Island and see if they still carry it. Mention seeing it in the review here and ask for tips about using it on a recumbent :)
Nice review! Would this kit work with a panasonic downtube battery as well?
Would these mid drive kits would well on an old single speed bike ?
Nice one as usual ....
I have MTB - talon-3 2016 model with hydraulic brakes.
I am confusing on two ebike kits, this one and the new Leed 500s front wheel hub motor.
What's your advice ?
you can program throttle only
Can you get excercise like with Bosch motor?
Hey Can you tell me which tires and wheels you have front and rear. The rear looks fatter.
Hello guys! I would like to upgrade my bike to an ebike and i''dont know which motor to choose...Im doing deliveries in a really hilly area and its really tiring to do 4 days a week... I would use the bike most of the time with pedal assistant and im doing a day like 40-50 miles .So what you think which would be the best battery/motor combo> 250 , 500, 750, or 1000? Any answer much appreciated!!!
So... this kit you can install on another electric bike and have two motors bike. Interesting if anybody has done it already?
Hi, I´ve been recommended this kit as the "best" alternative to the proprietary Bosch system. One year later... would you say there´s something better than this on the market?
Thank you.
P.S. I forgot to say that I want it for long-distance travelling, so its autonomy is my n1 concern.
Great question, I haven't spent a lot of time with this kit since reviewing it but every once in a while I'll see it pop up on a conversion that a friend has made. Here's a quick video of one such conversion from just a couple weeks back: th-cam.com/video/YS-_TT20KNU/w-d-xo.html as far as the best mid-drive systems out there... I think Bosch is definitely a leader but the Impulse 2.0 is also very good and Yamaha and Shimano are also entering the space (though I haven't seen them yet). If you want distance and care about reliability, this might be a great bike to consider: electricbikereview.com/focus/thron-impulse-speed/ but for the price and for conversions the BBS02 is still a solid choice in my opinion :)

Hey man, thanks for your answer.
The Impulse 2.0 does look like a much more sophisticated product, but AFAIK you can´t buy it separately, you have to buy the bike as well, ala Bosch. That´s precisely what I´d like to avoid, since I already have a very decent full suspension bike, so I rather put the money towards the best kit I can find, and/or some recharching solutions (My goal is to hit 100Km/day, which is something I might not be able to do with a single battery, so I have to think about some efficient way to recharge that battery, if that´s even possible at all).
If you have any other suggestion I´d certainly love to hear about it.
Cheers mate.
1650million Cool, in that case I think the Bafang BBS02 system would be perfect. You can get a bunch of different size and style batteries to work with it and it's fairly sophisticated and quality for an aftermarket kit. You might be able to ask others about this system in the forums or find a good dealer: electricbikereview.com/community/forums/8fun/ it's pretty active.
ElectricBikeReview.com
Thanks, I´ll definitely check that link out.
You can rebuild bafangs at home bruno teaches. 52v battery is all i need with 350 motor and i wanta 2 chainring bafang up front. Bafang Front hub, rear hub with cassette. Maybe a pinion in there somewhere. I like thumb throttle.
How many rear teath would you recommend for my 20" handmade bike with a 750Watt Bafang 46teeth on front? 16, 17 or 18? Thank you very much
Does it drove by two system? throttle with rear motor,and PAS with centermotor right?
What would this look like, if it was put on a fixed gear bicycle?
Hi , could you please tell me the autonomy without pedalling? thank you very much
If i've got a front shifter with 3 cogs do i have to change it to a single cog from this kit or can it be fitted to the one already on it?
Where is the controller on the bike in this video?
do you still own this bike? Is the Bafang reliable?
I don’t know about this reviewer. But I’ve put 1700 miles on this motor with no issues. The actual bike will break before the motor 😂
@@micah4255 That's good to hear. While something like Bosch is more refined, the simplicity of these motors appeals to me, and seems to make them more reliable.
Hi Electric Bike Review - thanks so much for this video. I am considering purchasing this kit and was hoping you could answer a couple of question: you mention that the kit comes with brake levers that will signal to the motor to stop - I am wondering if it is difficult to set these up ? Also, I notice the bike in the video has disc brakes - I assume this means the kit is compatible with these without any modification or extra parts? What do you think it would be like to ride if you just didn't install these break levers - My thinking is that, since the motor stops when you stop pedalling, and you would logically always stop pedalling when you brake, surely these brake levers are not necessary - would you agree or do you think the brake lever things are a must?
Thanks for your help
Hey Josh, the included brake levers are very easy to setup, they just have one extra wire coming out that goes to the drive controller to signal cutoff... the rest is the same. To set them up you just pull the cable and and endpoint out of your existing levers and unscrew them from your handle bars, then put the new levers on and replace the cable and endpoint. The kit is indeed compatible with disc brakes as well as any type of rim brakes but they have to be mechanical. You cannot use the levers included with this kit for a hydraulic brake setup. To answer your last question, no, you don't have to use the included brake levers. There are several purpose built ebikes out there that don't have fancy brakes like this but they are nice to have for a bit of added safety.
Este kit realmente parece ser bom, mas e a manutenção quantos km rodados eu digo testado. Ele chega ser mais robusto que um Bionx que esta há muito tempo no mercado. Acredito que a manutenção é um pouco complexa devido engrenagens uma eletrônica ainda em sedimentação. Você indicaria este kit para uma pessoa que ira rodar 65 KM diários, ele suportaria mais que um Bionx.
Hi Cleidson! Sounds like you have a long ride each day... One of the neat things about the BionX kits is that they are gearless which means fewer moving parts. This will help them last longer. That said, the 8Fun BBS01 or BBS02 will be efficient because it uses your gears for leverage. Either of these kits would be great and the nice thing about 8Fun is that you can use different batteries. With BionX, you have to use their system.
ElectricBikeReview.com , Obrigado pela informação, é que a gente fica inseguro até porque, a manutenção do sistema, como eu assisto todos os testes que você tem feito com todos os sistemas, parabéns pelo seu trabalho acho importante para que possamos até decidir sobre nossas escolhas. Fora esses dois sistemas você indicaria um terceiro.
Cleidson Torres Sure! I'm glad the reviews and videos have helped you. I've put together a "top 10 list" with ebikes I liked from 2014 here: electricbikereview.com/top-10-electric-bikes/ note that there are more than 10 bikes there... I just couldn't narrow it down :P hopefully this helps you out, I'm not sure which bikes are available where you live. Where are you from?
Hello ElectricBikeReview.com I was wondering would this kit work with a schwinn sting ray chopper bike?
Hey are you based in Naples Florida??. I’m wondering if you could help me out set up this exact bike 🚲 thing??.
Awesome! I'm looking to convert a KMX trike like this too. I have a question - is it possible to trigger the motor via a throttle lever instead of the cadence sensor?
yes
Why would you carry on pedaling if you want to stop
Hey just wanted to ask : if I buy this kit and I want throttle only , do unplugging the pedal sensor do the trick ? Cause I want to pedal only with my force or only use the motor power.
skrillex1234ful Great question, I'm not really sure to be honest? I tested this at Propel Bikes in NYC, maybe give them a call and ask?
skrillex1234ful With the standard setup described in this video, there's no way to achieve this. People on the Endless-Sphere electric bike forum have gotten hold of the software that allows changing the motor controller configuration parameters beyond what can be done with the display unit. It's possible to make assist 0 be a throttle-only mode. Do a search on the Endless-Sphere forum and you'll find an excellent thread that thoroughly discusses all of this. (See Barrent Hoffman's comment below for the Endless-Sphere link I was talking about here...)
ok thanks guys i have the anwser it's all programming the controller
Ben_j_bike or getting the newer color display and controllers. C850, c18, c750, etc....
Top speed on a flat, with rider peddeling (lets say 200w of human power)??
Thinking of adding this kit to a box bike (workcycle version of Bakfiets.nl, with the wooden box in front of handlebars where kids & groceries sit, then front 20" wheel in front of that. As the front has m81 drum brakes and hub generator and mounts for disc brakes would have to be welded on and back has that plus Nexus 8 internal drive train going hub motor would mean switching a lot out. So mid-drive it is. (Bike manufactorer version of e-assist is front hub 250W motor, switching out painted rim and adding magura hydraulic rim brakes, and chaining out lights, they are curious how it works out for me as are interested in trying 250/350W Bafang BBS01 mid-drive in future.)
My worry mixing this BBS02 motor (500W version, same motor but controller with lower setting 18or20amp max versus 25a for 750W) is the Nexus 8. Its not 2kw but your comments in video about grinding gears has me worried. I get feedback of others worried about this but has anyone actually ruined a drive train with a mid-drive less than 750W?
New to this, have bike about to buy this kit.
That sounds like a good setup. Here's a review I shot of the BBS01 (the less powerful version of this mid-drive from 8Fun). I think it would work fine with the Nexus 8 and have seen lots of other traditional mid-drive bikes that use a rear cassette vs. CVT like NuVinci. The only real downside is that you might not be able to switch gears at rest like you can on a NuVinci. Here's the BBS01: electricbikereview.com/8fun/bbs01/
Does the kit help without the battery?
I like your video's. Very informative.
Hallo, how many km you can make with one full charge?
Why the fork is wrong way???
I’d shredding those cables wrapped around the motor pretty quick
best review mate! keep it up :D
Can you suggest what & where I can get a power supply for one of these motors?
Sure, the bikes I tested were assembled by Long Island Electric Bikes and I believe they sell multiple battery sizes and configurations from AllCell. Just reach out and ask, maybe start from their product page here: longislandelectricbikes.com/bafang-mid-drive-motor-750-watt-48-volt-bbs02
Can someone help me with advice on getting the bottom bracket off a carerra hellcat, I got 750 bb02 or summit, lol, Its not 7 years old lol, Only bought it week ago, lol, Im having massive issues with getting bottom bracket off my carerra, Need to sort it, My electric monster scooter started playing up today, Plus be good to have a change to an E-bike, So can somebody please drop me some advice on getting a stubborn bottom bracket, I dont have any power drill either Is there any tips too loosen it without breaking my back or hands, lol, I really want this install done now...
So what if I installed this on a bike with a rear hub moter like the izip e3 dash
dillon hand Well... you'd have to figure out where to put the second battery pack so the bike would be a lot heavier (likely 15+ pounds) but my guess is that they could work in tandem and just add more power for climbing and stuff :)
I was thinking about getting the emotion jumper, the one you own. could the battery pack from the 8fun connect to the underside of the jumper? I notice since it has smaller wheels, there is more clearance.
dillon hand Neat idea but I doubt you can mix batteries. If you're looking at adding batteries then start with a kit like the 8Fun BBS02: electricridereview.com/8fun/bbs02/
so I have a 1000w hub would this be faster than the that .
This pretty much is exactly what I want, but the kit costs more than some entire electric bikes. I mean, if the battery runs $800, I may as well buy an entire bike. Does anyone know of a good mountain bike type mid drive that has the nuvinci? I don't want a mid drive without that.
Is this a re branded ERad? Or are they actually different?
That's a bad boy there.
Forced pedal assist? Screw that controller then. Besides you can do twice the power at 2/3 the price without 8fun's help. Really like that continuous trans rear axle. Looks spendy too. Mid drive man on a rear hub budget in my world.. :) Nice bike.
Would this fit a Gary Fisher Superfly from 2009?
Bosh and othr factory installs dont even compare torque wise to the Luna cycle motors. It's been tested trying to carry a 300 pound man. the factory bikes wouldnt even move uphill. the Luna cycle carryed him up the hill at 26kh
what drive should I us on my pedicabs
Any suggestions for best kit for 2017?....2018
