- Putting together a 3000W rear hub drive electric bike. 16AH 72V battery. It is illegal to use on public roads in most countries. This one will be used off road only. The most important part of this build is the custom torque arms. With this much power, the small torque arms can snap the dropouts on this frame that was never designed to have power put through it like this at 11:17. From stop, if you twist it to 1/4 throttle or more, the bike will pop the front wheel up and flip you over. It is very unsafe, I wouldn't recommend doing this build to anyone, it just doesn't make sense.

@@porkerconhow do you trust aliexpress man? I've heard of people getting scammed and am so weary of it.
@@No-ju9xz Just do a credit card chargeback if you never get the item
Pedal assist sensor goes on the other side of frame on the non-drive side of the cranks.
@@porkercon aliexpress seriously? 😂😂😂😂😂😂
Nice video! I used UPP cell batteries on my ebike and atv, and they are extremely well built as seen in tear-downs. Highlighy recommended. They make universal tq arms I show in my bike video. Yours are gnarly, and in a good way- should have room to grow with that setup; thank you!
Upp are poor quality. Banned in UK for fire hazard.
@@Tomas-ml9nv It's like places banning Juul, they just target the biggest manufacturer representing a market. I've used, tested, opened many lithium battery packs. UPP , in my experience, uses better BMCs, double solder points on cells, and they're internal wiring further showcases their workmanship. Others I've purchased have came w wrong power supply, have shody wiring or BMC failed. And even more I've purchased were actually UPP batteries rebranded. Nonetheless appreciate your reply and input! whatcha using in your builds?
Did the same but with a 1500w motor on my mountain bike. 35mph feels scary on a bicycle but really fun at the same time.
@Bikes0420 there is nothing the law can do man.
You can do up to 50 mph before bicycle frame without proper wheel alignment, balancing etc will become unstable and you start getting wobble in the front
@@user-oy9zy4ds9m i start feeling a bit unstable only im approaching 40mph downhill at full throttle, i limited the bike to not go beyond 35 and generally with the resistance of the motor it wont go faster than that even downhill.
Yeah I got 3000w ebike with 52v 28.8ah 29er on slicks it will do 45mph and you can feel how light the steering is because of trash weight balancing
Wanna upgrade the battery to 72v at 40ah but unsure as the balance of the bike is way to far back for my liking
I made my torque plates and bolted them straight into the frame. 10000 watt hub and controller. 84v main and 12 vt booster all together 96v
That sounds insane. You got videos?
@@yeredfarias7662 😅 What is the video you would like me to create? I made the bike but have no decent camera to make some quality riding videos. I will make a phone video of anything.
@@soylentgreen9492 anything really lol. Was just curious about the bike frame and if you got fat tires and if it hooks or spins

It goes very fast. I cannot ride it past 60.
Everything is different, The brakes are 205mm rotors
I wired the lights and turn signals. It outruns most mopeds but I never race.
You should be able to swap the 5 speed cassette with an 8 speed one and have it take up the same amount of space. The 8 and 5 speed are the same size, just on the 8 each chainring is closer together.
Edit: Also, pretty sure the pedal assist sensor goes on the opposite side of the cranks to the front cassette.
I put basically the same motor on a stealth type frame in 2021 (3000w) and I love it. It's my daily driver...weather permitting. The frame is quite heavy of course but I decided to go for something that absolutely wouldn't fatigue over time. I wish more people could experience how much fun these big motors are, thanks for posting.
This is like a daydream I have about building one! Very nice
Building an e bike is not a crime.
Riding it on public streets over 32km/h is
They only know it goes over 32 km if you tell them
@@porkercon Not really. It's still a bicycle which means it has pedals that can be used to increase your speed. I can cruise at 50 kph on a straight away.
Does when it's motored?@@ProfessorStephon
@@ProfessorStephonwhen you ride over 40 on a motored vehicle like this it would be classed as a motorbike
The 11,28 tooth freewheel is a must upgrade.
I got one of these kits on a $100 walmart bike still running fine 2 years later!
$100 is a steal
I'm surprised the torque didn't rip off the drops
did you watch the whole video? holy
@BoscoLe not of yet lol admittedly I missed last part as the phone rang the door knocked and I needed a forest gump.
I never had problems with my axel drop out. Only made one side torque arm set up
Pretty cool.. Yeah, some controllers you can program to have milder start up or delayed power at take off. Or the display will actually have settings for take off sensitivity.
This is great to know
The pedal sensor is designed for the left side and seats in to the bb
Yes, that is correct on my ebike DIY build you will see I put it on the non-drive side.
Should i do 3kw or 5kw?
Were you eventually able to get rid of the check engine light?
Having a check engine light on your display can be due to multiple factors. You should look for the error code written on the screen and refer to your display manual to see what is the error related to.
As for the pedal assist sensor and magnets don't put it on the crank side put it on the other side that's what I did and it works just fine
How is it climbing steep hills?
Very well
Anything over a thousand Watts you can climb pretty much anything
Im 300lbs and just converted with 1000 watt and can get up most any hill. Im sure he has zero issues
@@jjmcwill1881if your 300lbs you should be on a pedal bike only shit no need for a e-bike need to get that fitness in 😮
@@Fulldrawflickingandstickingbruh
Can this be put on a regular 20" ebike? Would putting it on the front wheel for front wheel drive be more stable?
Probably not since the motor is so big, front would be fine but would put a lot of force on the fork.
Looks like there is 20" versions of 3000w, scary.
4:22
Very good point to check.
I was in the same trouble. I had to grind and reshape dropout too. Very hard.
Hello mate im a fan, absolutely love the brillant torque arm design but i have got one question. How do you stretch out the frame by 2.5cm like what u mentioned in the video.
By pulling it with your hands, its not permanently stretched, and its not good for the frame.
@@porkercon using a 5000w motor and its axle is longer guess i dont have any other choices right mate
@@zephyrus3389 right, might have to do some frame modification
do you know if it out run the same if i only used a 1500 watt motor?
my friend the controller straps wrap around the bag first and then they stick on the velcro, if that makes sense
Where we can order
I have a similar kit and the velcro on the controller bag makes zero sense
can you please confirm if you bought from that exact seller? ND Ebike Factory Store- this seller. I had problems with scammers this year on AliExpress but I want to order this kit. Thanks in advance
We have bought multiple different kits all from different sellers and have had no problems.
@@porkercon 1000w is the easiest to buy, but this 3000w doesn't have many sellers
@@porkercon I am looking exclusively for a mtx set
@@pubga5730 Usually you can customize your order with which rim you want
@@porkercon in Europe they have max 1500w 48v
I’m doing a similar build on a fat tire e-bike I would love to compare notes if you got the time
6:00 If they had stored the velcro straps wrapped around the bag as apposed to around itself it would have been more obvious how they are supposed to be used to secure the bag. The velcro goes on top. at 6:13 you have the bag upside down trying to install the bag as though you'd be wearing it as a fanny pack. The vecro goes from the top, around the bag, under the panier, back up around the bag to the top.
I think we tried that but they were too short. Its now directly mounted to the frame with no bag.
@@porkercon tyraps ftw
Did 67.1 mph on mine. It's a blast.
is the throttle response instant or is it slightly delayed
instant
How much the price
Where did you got your battery bag dude

What would be advantage or disadvantage to having battery on rear rack?
Advantage, leaves space on frame, disadvantage, puts all the weight on the rear tire, front end would be very light.
Hallo, erstmal, wie hast du eigentlich das Hinterrad hineinbekommen? Die meisten Achsaufhängungen haben doch nur ein Rahmen Nabengröße von 130 mm sprich 13 cm und das 4000 Watt Modell hat doch sicher 150er spricht 15 Zentimeter. Narbenaufnahme, wie hast du denn die Hinterradnabe, in die Aufnahme bekommen? Das würde mich jetzt mal interessieren. Schöne Grüße von Christian!
Road bike is 130mm, mountain is 135mm so its fine.
@@porkercon Nein ich meine der Motor die Nabe das umrüstset hat doch 150 mm wie hast du das gemacht das es rein passt den Rahmen auseinander gedrückt um das Rad rein zu bekommen ❓
@@UrbexDerWeltenbummlerChristian This one is set to 135mm, you are looking at a different one.
I thought the crank sensor goes on the other side😮
i just got this same kit and putting it together. can you just not connect the pedal assist if you dont wanna use it? and same for that alarm system with the key fob stuff? not sure if some wires need to be shorted together or no... mines got a 48V 1000W on front and this 3000W on rear.. lol😂
Just don't connect them
What is the reng?
Put it on the left. Flip the PAS magnet over.
5 speeds on a 3kw hub is actually decent. Many are so large they're strictly 1x
Sounds like a lot i might as well just get a acutel motorcycle, for as much money as this will cost right?
No, its not that expensive. But for many other reasons a motorcycle is a much better idea.
Yes friendly advice you can't stick pieces of metal on top of weak metal and claim that is strengthened it because it won't what you've done without sounding rude is you bogged it what you should really do is cut the whole part out and put in stronger metal you're basically Dublin the speed of the bike but you're not doubling the strength of the frame to carry that and you will pay the consequences because you'll start cracking Worlds stability at high speeds my device is cut the whole back part out and easy peasy to world of fresh bit in you can weld it wider to fit the wheel in and you can weld it stronger which will last and will be a solid piece of metal always always uses less metal as possible because that's where your strength comes not by putting one piece on top of another piece unless it runs down the whole length of the frame good luck don't gamble your life on I'm sure that'll be alright
You're wrong, I'm right. Buy us an aluminum welder and training and I might do what you said.
@porkecon is right because these hub motors are not powerful enough to rip apart whole rear triangle of aluminum mtb frame. These torque arms ar mainly to strengthen dropouts because without toque arms you will break original dropout slots when accelerating and motor will rip off it's own wires😂 cool project btw
Bike name like the bike u put the conversion on?
@@mrWantsMx650Parts Diamondback Tapanga
thank you for this video, I am going to be building my own ebike from scratch, so I will make my own frame, do you know how far the brake disk mount is from the centre of the wheel, and what is the width of the tyres? thanks
I don't and 2.35
can you climp a hill with that setup
yes it has a lot of torque
I don't understand why you build something like this if you are so negative. Then spend more money on better parts, frame, controller, etc. Btw, you don't have to install the pedal assist if you have a throttle
I didn't build it, someone else did and I filmed it. We are aware of that but we want the option to use pedal assist.
Where did you get the bag?

What speed can it take a bike to?
83km/h
How fast does the battery charge and what is the max Amps u can charge the battery with
I charge it at 5 amps, takes 5 hours. Max rate is 10 amps.
Anyone know the “ideal bike” for this wheel?

Hello my friend, is it possible to install a 3000 watt motor on a 15 amp V48 battery? Thank you
I think its possible but it wont run at 3000w
@@porkercon thx
Why do people use disc brakes on bikes?? Doesnt the v-brake have way more stopping force because it is farthest from the center of the rotation? This is just basic physics. Or do people get discs for vanity?
Rim brakes are good yes, discs allow you to have a more predictable braking surface, better modulation, better pad material that you can't use on rim brakes. Way to many reasons to go disc when the only reason to go with rim is the distance from centre of rotation.
Biggest advantage would be if he installed hydraulic brakes. Mech disk brakes are about the same stopping power as good v-brakes, but the disks do work a little better under certain conditions, like if the rim gets wet.
@@miket.220 th-cam.com/video/NCdobNDttMM/w-d-xo.html
V brakes are fine for pedal bikes. Leverage isn't the only factor to consider. Pad surface area and cooling play as much if not more of a role in terms of stopping power. That's why you don't see v brakes on motorcycles. You won't even see them on manufactured e-bikes unless they're cheap or underpowered. That little thin strip of rubber operated by cables is not sufficient enough when you add a 30lb+ motor serving as an unsprung flywheel outputting 10 times as much power as your legs can do. V brakes are designed for leg power, pedal bike weight and speed. Disc brakes are designed for high speed performance on a motorcycle or downhill racing mtb. A good set of hydraulic disc brakes vs v brakes is like the difference between night and day on an e-bike this size.
hey i was just wondering if its safe to buy ecerything off aliexpress did you buy it off there if not can you send me the link to the other websites where u bought them off please reply
ya
How much for my carrera
Is this 135mm or 142mm dropout
135
Hey man, decent build and good tutorial, i was considering something like this but also was worried about the frame handling the torque, so my theory has been to downgrade to a 1500w 48/52v and just be happy with that for some fun around town and off road weekend rides, do you think i can get away without using a torque arm, or would you say to at least use the original 🤷🏽♂️👍🏽
yep, 1500w is great, 3000w is overkill. My friend has about 6 eBikes right now and he uses the 1500w the most
@@porkerconthan you for your quick response 🙏🏽👍🏽with or without torque arm, I also know of the trick to remove the plastic spacer on the disc brake side from factory, but I'm having slight issues, so the rim fits my frame with all the nuts and spacers but the spacers only fit outside of the frame if I put 1 behind and the other outside with the nut it won't fit between my drop out but it is the correct hub for my drop out,,, any suggestions please.
I'm not sure @@DarkTriad6
I have a 1500W/52V kit (does about 1750W fully charged), you're gonna need at least 1 torque arm, or it might spin out of the fork at full power...perhaps not directly, but certainly over the months. I haven't removed my wheel in 2 years since I built it
If you're gonna use regen braking, you might even need two torque arms, as the force applied reverses when braking.
@@porkerconwhy would you say the 3000w is overkill?
Would this kit fit in a 26” nakto supercruiser?
nope
I don't know if you mentioned it but how many amps is the controller?
Nevermind, I just saw the sticker, 60A peak. Probably 30A nominal.

Terrible frame to do this with. Has no suspension, it's a waste of Battery and Motor. Get a better frame with full suspension
Such an inspiring comment. Not very hard to swap this onto a different frame down the road when the BUDGET for this build gets HIGHER.
Tbh with a triangle battery 72v that size, you’d struggle to find a full suspension bike that could fit the battery, you’d have to get a 48v
I have a nearly identical setup using a 17.5 hardtail with everything else upgraded. Same bag, same hub size. 1000 miles so far and it's great.
Might be illegal but they'll never catch you lol.
I've been thinking about building.Honestly, that was my same thought.Just put a single speed on there and drop the de-railer
Although I'm doing full suspension
where are you gonna put the battery on a full sus frame
86kmh=53.4 mph.
‘Off-road only’… That thing would kill you off road for sure.
😂😂😂😂
nothing is illegal as long as you don't get caught
All that extra strength? Off road use only? My 3000w motor with an 80 amp controller on a 72v 20 a/h battery does 65 mph on a 25 year old Kona mountain bike and I use it everyday to go to work on. Most times I am at full speed going to work and I only use 2 torque arms with no welded frames for extra strength as its over kill and it's perfectly safe if you know how to handle the immense power it can throw at you. Nothing is too powerful !
Frame is not welded. Better keep an eye on your dropout welds.
That's sickk have you got any links of what you purchased I want to do the same on my bmx

they confiscate them, so they got to be housed somewhere, otherwise, they'll just be destroyed or scraped,
Nice build! Very similar to my bike.
Sick build man, currently have some similar in the works but a bit lower power so I don't die lol
Good idea, the owner of this rarely rides it because of the danger. He likes the 1000w-2000w range.

What kind of range do you get out of battery?
50-60km when going fast and not caring about trying to preserve battery. There is a video in my shorts of it driving by.
