This is awesome. As a Tasmanian rider with a max legal power of 250w, my favourite part just might have to be the sticker though... ;)
Dude.. is that everywhere
I just bought a 5k kit of Alibaba and now I can't ride it.shit
Jervis bay oz
@@matthewallen1394 add a fingerprint sensor. ill bet there is some Relays & Arduino that can be used, "locked" 250/300W 25km/h & unlocked max speed/torque and "dead mans switch" remove thumb and lose power.. use it smart and you'll never get caught.
@@johanandersson2165 Awesome.
_"might have to be the sticker though"_ - if it's in Chinese it might not matter that much.
@@beachcomber2008 google translate on phone ? just add a fake 250W sticker they sell those too.
absolute g thank you for taking the time make this, epic dude!
Awesome job!!!! And the video with the footage is crazy!
@Edser electric I love how many replies you have given to people with questions. Great job helping the E.V community.
Thank you, that is what I am hoping to achieve with my videos. Showing just how easy and cheap it is to make wicked electric toys these days, which hopefully helps to build the community ✌
@@jd-dc hey bro do these kits come with the battery or do i have to buy on its on if so where do i buy
This is the best ebike video I think I've ever seen even with the music the talking can be distracting I want to do this for a living now!
Amazing build!
Keep them videos cooming 👍🏽😁
Best ebike diy video ever!
That's a big job you made it look easy
haha ripping on that little track above Harry shaw way!! Great conversion, keen to do something similar cheers for the info!
nice modification and cheap. keep it up
i shunt modded my 3kw controller, before the mod it would do 75v x 60amp for 4.5kw, i did the shunt mod and got it up to 75v x 90amps for 6750watts, it lasted 3 nights of easy riding and about 5 miles total before it blew caps and other things on the board. i since then got a much bigger "3kw" controller that i think was marked wrong as its so much bigger and heavier, can go up to 114v and a max of 80 amps for 9.1kw, i shunt modded it too, but honestly i didnt even need to and its built like a tank, i have put a few thousand miles on it and i push it pretty hard sll the time
How fast does it do. How much do you weigh. Where can I get the parts
@@novaturbkkk with the old controller i had it up to 60mph one time to see how fast it could go, it had a bit more power in it but 60mph was already too fast. i have since upgraded both the controller and the motor.
weight really isnt the issue with top speed btw, me and my bike are heavy. i am stronger than average and can barely pick the bike up if its fully loaded with all the battery and gear, plus its awkward. i started with a 3kw rear hub kit from ebay. just find the size wheel for your bike, get that kit, and get a battery. batteries are expensive, and i normally only go about 30 to 35mph, anything much faster and it becomes too stressful
U r truly a mechanical engineer bro 👌🙂👍👏
I have to try this with the aostirmotor s17,nice video my friend!
This bike is epic, love the cooking mod
My favorite part of this is unlike the other madlads doing things of this nature you, like myself actually wear a HELMET.
NIce work on the shunt ! :D
Thank you, it's crazy how much this controller can handle
Giant ac most versatile bike in the world had 3 of them from cross country to free ride they do it all!
I lliked the music starting @ the 8:40 . By the near the end I was loving it
Now that's an extreme mod, I like :)
Dammit... I knew the little motor had more in her. I built one last year and went with the bigger QS motor as I was not 100% on the tuning, I ride at about 6k max anyway and the lower un-sprung weight on the back wheel would easily make up for the diff. I have recommended to so many people to get the little one and try something like this but I have never seen it done. Nice.
protip:
If you want even *more* power, it's possible to do a cap and FET swap for 100v rated components. the bones of these generic motor controllers is capable of taking north of 88v if you spec the right MOSFETs and main capacitors...
Before changing over to a pair of VESCs, I used a pair of shunt, cap and transistor modified controllers on a 76.8v LiFePo4 battery for a total power output of about 6kW AWD... from bone stock 1500w motors as well. They seemed to handle 3,000w at that voltage shockingly well since I never ran into heat issues or even hot phase wires on both the stock motor controllers (which were a pair of 500w jobbies initially), or the motors.
I have a Mac chain drive motor that was originally only rated for 48v 1000w but I've pushed 72v 7.5kw throw that thing and had zero issues yet, just hit 200miles on the build too
@@MrJasenstewart97 i just got a 500w cheapo off amazon and i already suspect that it can handle much more than it's getting.
In the setting I was able to disable speed caps and was able to go from 20mph (locked) to topping out at 27mph with the stock 48v battery.
After riding it wide open 6 miles to work, the motor hub isn't even warm to the touch. It doesn't seem to be working very hard. I am new with ebikes but I spent a lot of time building 10th scaled off road rc and you knew when you were stressing the system when the motor was too hot to touch for more than a few seconds lol, that was the in field method of checking the stress on the motor with whatever gear ratio/battery setup you had going. point is i would run 3s into a motor that was rated for 2s and beat the living hell out of it, competing with motors that cost 10x more no problem lol
I am thinking about dropping a 60v in it and see what it does with that. After that point i will need to get a different controller in it if I wanted to go to 72v.
The stock controller can be set for 36v 48v 52v and 60v
I have a target of ~40mph with this particular bike and I am going to see if we can do that on the stock hub lol
@@eonreeves4324did it work, I'm interested??
@@mickyb.8014 haven't tried it yet lol the battery pack is pretty expensive. I'll get to it eventually.
@@eonreeves4324 oh ok, well thanks anyway, I'm thinking of getting a 1500w 48v rear hub kit to slap on my 26" mtb, I'll be getting a 52v triangle battery, hopefully 20ah as it's all hills here in the U.K where I live...
I'm just trying to gather as much info before I buy a kit/battery...
Kinda torn between a Voilamart or maybe a ebikeling kit, if you have any info on which is the best affordable kit it's greatly appreciated...
I'm expecting to pay no more than about £650 (got bike already) for the kit and battery.
Cheers.
It's so delicious it's like adding more cooling to a gpu or something but for fellow traveling
What battery did you use to build the 1500w bike originally and what’s the top speed and mileage?
Well done, I´m trying to adapt somethjng similar, a 48v motor on a 17" motorcycle rim, it´s extremely hard
you legend awesome just what I needed to actually do the same thing but was really stressing about just about to start mine thanks for taking the time to make this
did ya make it?
@@hrideshbudathoki3380 of course he didnt, just big talk on the internet
Im doin same thing to my voilmart i have 36/48v 50a brainpower controller n 2. 17.5 ah batt getting 48.7 mph the heat i drilled holes now thinking rc moror fan inside hub mounted for cooling or a 12 400w car cig lighter plug in dc to ac 110 converter has a small fan 12 v might use also
Got damn sick video bro , I have the same kit 1500w 52v on my fat bike and always wondered how to make it acceleration faster, do you think I can get away doing this mode without using ferrofluid? If I'm not planing to go full throttle all the time.
Thanks dude
Awesome bro yes definitely, you just need to keep an eye on the temperature of your motor and controller, and make sure the battery can handle it. I ran it like this for a year with no ferrofluid or hubsinks and I couldn't see any obvious heat damage when I opened it up. Depending on the type of solder you use and how much will dictate how much the power will increase, I used 50% lead solder for minimum resistance, maximum power
Following your advice for the controller I made it to pull 130A at peak. A bit too much. Not saying I don't like it but my batteries bms are 50A each
this adjustment is very interesting. can this modified control unit still have 3000 s hubsink and ferufloid ?? how many volt batteries do i need for this unit, thank you for your reply
I wish I had the tools to do this! I may have to resort to purchasing one already assembled.
Buen video amigo. Yo la mia la tengo limitada!!!
sick ass build
Thanks bro! It's an ongoing experiment, I'm going to cut out the top main frame bar and use carbon/kevlar to build a stealthbomber style battery box in its place soon so I can add more batteries, thought I better add some cooling first though
so if we change the whole controler???as probably it comes with the new 5kw motor, and what do we do with the battery?
there is an 2 part epoxy thermal glue I used on custom built heat sinks for ram and other components..never tested it against a clamp system and thermal paste but did see drops in temps with ram on video cards and computer ram..there are different grades of thermal paste that work much better than just 2 dollar generic thermal paste..Artic Silver is the best I have found..btw he did use to much paste..more is not better..then thinnest coat possible is what is best.
That’s where I just got 12 pairs of brake pads for my aventon level only site that has correct ones by pic!, took about 20 days to get but I got 12 pairs for about 21 dollars the same price as the bike shop charges for one pair normal price
Hey mate great build what voltage is it running at now
how do you ensure safe charging? would it be at risk of exploding? how about if left on charge too?
On the engwe x26 bike … your opinion on simple upgrade to 50mph bike?…. Basically a typical rear 750watt with weak controller…main goal is better response on throttle. Am I better off replacing controller or fusing it like you did?….thanks
hi JD-DC. Im new to tinkering with ebikes. i just bought this kit you upgraded. Before you tinkered with the shunt in your controller. did you run higher voltage on the system than its rated for? I can easily build any battery pack, but i was wondering if i should build the battery pack with a little higher voltage, than rated.?
How big a battery pack to you build? I love this build and I'm keen to buy a suitably sized battery pack.
Your a legend 👏...please can you tell me were to find the road legal 500w stiker..as I was looking yestoday on line ..to no success. Only found 250w ..wich I won't get away with
Awesome vid. What batteries did you use?
So epic!
Man that statorade ain't no joke ...proof is in the pudding
Nice work. Curious for measurements.
Recommendation: remove the yellow black connector. Mine caused a controller fail.
The one with 3 wires where bolt and nut connect
Thank you, yes good call I have heard that they can fail, I've been looking for a suitable 3 pin plug but most of them are pretty small so I'm thinking about using 2 xt90s for the 3 phase wires. It's a 205 hub motor, KS brand on the side of the motor.
For the plus 30 A I am experimenting with big plugs. I cannot find a name. They can be bought on Ali. Plastic big car plugs.
paint inside of the motor in dark black. the shell absorb heat much more
SUPERB. i got a FOREKNOW fat bike and put 1500watt motor and controller. 52v 21 amp hour Battery. It's a heavy bike. up hill 24mph .. down hill 45+. i need more torque more than distance.
This is will try. PS... i have seen people fill the controller with a heat conductive resin to dissipate the mosfet heat to the outer casing... any thoughts on that? Thanks.
Does the statorade interfere with the Hall sensors at all?
hey thanks a ton for this video, i just have one question, do you thing it is possible to do the same to a 1000W motor? thank you so much for the video!\
Nice bro
awesome. thanks!
That was useful. Thanks.
your welcome
Bro how are you filming yourself riding the bike? the camera turns and everything 👍
Love the video just a quick question I’ve got a 1000w kit with the shunt mod so by doing the ferofluid in the hub will make it higher the the 1000w? Cheers
What the shunt mod does is allow the controller to draw more power from the battery pack. If your controller supports the extra load(always check!), then that's great.
As for what the ferrofluid, it is used for decreasing the thermal resistance of the motor to the outside, allowing it to be cooled more effectively.
On your 12 AH battery what is the continuous. No where near 80 amps i bet . If so what cells you using? Batteries wont last long may even burn.
I find much to recommend this frame design. Any hints on how to descibe it for searching / shopping?
Nice job, do you still have this build running good?
So can I under volt the controller bc I want to use my weekwacker ego batteries?
what do you mean half throttle for double power?
Do you think it can handle 30amp cont and 60 peak without the heatsink etc
Nice work 👍500w sticker 🤣
How fast did you get it up to you never mentioned that? Also could I do the same with a 350w kit to test the theory try get 350w to 1kw atleast I already have a 1kw bike but it’s for work
Great video I've built an e scooter using a 1500w 20 inch wheel kit running 48v 17ah battery if I just solder the shunt together will that give me more power? I'm a Newby to electrikery tinkering.
Yes that will work, just make sure your battery can handle the extra power. There are lots of videos on youtube of people doing close up shunt mods if you search "shunt mod" you will find some more in depth instructional videos
How to you keep your batteries from heating up pulling 80A!
Hello! How many NM torque have at this time? And max speed?
Is it OK to do drops and jumps etc with a massive hub motor?
Does such a Controller work sensorless without using the Hall sensors?
Man I’m looking into doing this to my mountain bikes this is my first stab at this I’m confident in my tinkering skills as I work on me and my buddies one wheels and I’m not afraid of working on electric is this something that a beginner is capable of ?? Any tips would be greatly appreciated or any Improvements or things you would have done or gotten better I would love to know I want it to be powerful and a blast on trails like I do my OneWheel so I’d love for it to be able to do 40+mph thanks for this video and the secrets !!!!
The bike side of things is more technical than the electronics, you need spanners, allen keys, and a crank puller (they are very cheap if you dont have one), as for electronics, unless you are modifiyng the kit you probably only need screwdrivers - so yea, as long as you are confident at stripping down and re-assembling a bicycle, the electronic side of things is pretty basic.
Quick question what was that black liquid you were putting in the Hub motor and what does it do
Hello. I have already built a massive 48V battery for this kit and I wouldn't want to build a new one for increased voltage. Do you think there will be benefits just by doing the higher current mod?
Also, could you please tell me how many magnets does this motor have? I seem to have wrong settings in my bike computer... I don't know what number to put in the P1 setting... (kt-lcd3 is the display/computer)
I also don't know what to do with the P2 setting :"D
in my area e bikes are highly illegal but no cop can catch me thanks to this😂😂
What is and where do you buy 'Statorade'?
Also, know anywhere selling 250w power stickers???
Hi there, just popping by to see if anyone can help. I've purchased a 250w e bike conversion kit. Currently I'm getting the 03 info pas error code. Everything else apart from motor seems to be working, any ideas?
Love your work mate!! Hey are you, or have you, looked into lithium polymer batteries to lighten the bike up??
Yes my friend runs his on lipo batteries, they are great. I am building a new battery from 21700 p42a 4.2ah cells
lipo are less energy dense that lithium ion so they are a tad bit heavier, but they can deliver more current and charge faster, i run with 3kwh of lipo 66.6v x 44ah
@@jasonbrown467 66.6 noice
The reason for it being hotter is that the bro will be running flat out top power instead of the less draw of your bike to achieve the same outcome making the less powerful bike straining and your product cruising more gently
man i could just kiss you right now going to turn my old dirt jumper into one of these
What's the distance you can travel on full charge
hey do you know if there is a hub motor kit for BMX bikes??
I was going to ask where can you get stickers like that, then I checked. They have them on aliexpress.
Do you reckon that can be done to a 1000watt engine soldering the two bridges together
Yes, you should be able to shunt mod most non programmable controllers. Just make sure your battery will handle and be careful not to generate too much heat with the extra power
I would think you would just need to hope it has good enough components to handle the power
Great video.
I ordered a 36v 20 ah lithium battery befor months.
It didn't deliver it ant respond
I have a 1500w/52v system with solder shunts, but I’m not able to get passed 26amps. I wonder if there is anything else on a control that restricts amp flow.
If its sw900 controller, in settings menu, go to p14 and set it to max amps your battery can do.
outside 30c inside 100c,inside temp sensor is a must.
Hi I've got 4 shunt in mine what do I do
Which heatsink kit did you order? I see they have quite a few options. Thanks!!!
I ended up going with the QS205 and it fits great
do the stickers work , should have been 250 for uk .
That’s where I get all my brake pads hub motors etc etc they send it
Cooked anything on the controller yet?
What battery are you using in the video
Awesome video! Do you think i can do the same with my golden motor magic pie external 1000w?
no
Great video! Congratulations.
Let me know your opinion, what is the better option motor to climb like this, 48V 1500w direct hub or a 48v 1000w geared hub? Thank you.
Thanks for the video ! very valuable info ie: ferrofluid , heat sink.......... just top notch ! Question: I know you are using 1500w kit but what if I want distance(not speed) and on flat service better to go with 250w?
9kilometers or 80 km? it will depend on capacity of the battery and discharge rates,,with his set up it is balls to the walls current draw, you would need a much bigger battery! but with pedal assist modes you can limit the current draw too! I love ebikes!
What does the ferro fluid do?
I've got a Prague e bike 25o same motor I've had a 80 amp controller w 72 v motor
what are the tools i need for this?
in Germany they check top speed and fine 3000$ if it's higher than 25km/h
Hi what batteries are you using
JD-DC excellent vid bro , I have purchased all the same waiting on thermal conductive grease... but I have set it up in the meantime and standard 48v 15.5ah battery I got 63kmh ... once do the mod and add the 72v 14.4ah battery what speeds you belive I should get brova from anova mova ( roughly ) what speeds you getting please
Hi JD-DC I did everything as you have ... all works with 48v battery but when I put my 72v battery it turns on when I press Throttle nothing happens can you email me let me know your thoughts please
Looks like they may have modified it mate its not working also the so called little shunt you soldered up doesn't make sense as on the back side its already together!!!
Anyway doesn't work looks like I will buy a 72v bigger amp motor controller instead to make use of my 72v battery I purchased ...
You might wanne wand the contact with the motor for netter Heat transfer
