How To make an Electric Bicycle (Brushless Motor Crazy Torque)

To order customized PCBs for your projects:
www.nextpcb.com
In this video we are going to redo the conversion on our bicyle using a powerful brushless motor while replacing the old geared DC motor.
Earlier we have converted our bicycle using a geared DC motor, though the conversion was sucessful and we were able to get thing rolling but still the top speed and the torque provided by the DC geared motor was miserable.
So we decided to step up the game and eventually we come up with the idea of using a brushless motor from an old hoverboard and some high discharge lithium pollymer batteries to give this bike a puch of power.
The conversion was stright forward as we tried to eleminate as many unwanted parts as possible during the process and thus we were able to achieve a top end speed of nearly 40 km/hr (The bike is surely able to get double that but the speed controller we had was able to handle only six cell lipo pack) and the torque was phenominal, seriously wheelies on the go.

i had made something close to this but didnt re wire the motor, used a cheap sensored controller, and had way too low of a gearing... i had 3d printed a tpu adapter for the bottom bracket of a bmx bike to fit the shaft of the hub motor. I like your solution... the torque you have got out of that motor and gearing combination is wild! Props!!! thanks for sharing!

awesome man i thnik its the only diy channel in pakistan with good vloging skills

[@electronic7979]

Excellent project

[@ryanlebeck259]

I would like to see someone convert 2 electric bicycles into a four wheeler that is also electric.

[@blanco5099]

Check the channel jegringeverything

[@maxl7827]

jerryrigeverything did that

[@itwasrightthereinfrontofyou]

Climp any hill with a small boat starter motor. If you were 90 degrees with front install, it would flip the rear up so you could face plant the wall/mountain/rock. If it were rear, you would be flying up the stairs in a wheelie. Make sure to feather the brake. Take one of them diesel lithium battery starters rated at 110v 100amps with a pwm(pwm brush only much stronger than brushless..brushless made for long distant constant...not best for torq). So yeah, Stunt guy like you, use a small starter motar which could pull a car at 2,000 lbs. Infact for the ultimate short burst that will climb anything use a 300 amp pwm(max hard to find- can get 150amp pwm) and you could flip get air on those stairs and flip with perfect landing. Another thing you can do is upgrade you control box to 5,000 watt 96v and overload brushless(500 watt brushless handle it for short bursts 5-8sec under heavy incline . 750watt 8-14. 1000 watt for 19-25 1500/1800 26-36 2000 47-60 and a bit over. 3000 1-2 mins.

[@Octonthabeat]

please!!!!! give more detail about the rewinding process i want to complete this same project

[@leonflores2933]

Who gets excited about 14km? This guy!! All that work just for 14km

[@AARTI42067]

40 not 14 and also if have pleanty of torque so we can gear it down to around 100 🫤

[@idaniamairena4191]

A fun, practical & affordable ebike

[@sskiinventions5820]

Well Bro How Much Torque does The Motor Gets And How Much Volts Does The Motor Needs And What ESC did you used In this Project And Whats the motor and ESC Specs here

[@julianwright6012]

I am full of admiration for your project. Also, it is very well presented.

[@infoakp]

I need the Phoenix crank plz give the address.

[@petrusobuta9691]

Please tell me how to connect the circuit of motor of the hoverboard. Please

[@kadatis]

Very good idea and job ...I want very well one lake these ...good luck mister ...kadatis from Algeria

[@hongyangjiang4976]

Nice craftsmanship.

[@sanjaynimje6567]

Very nice👍👍👍👍👍

[@hOZish7]

Some excellent work here but some of the decisions are a bit weird. Perhaps it makes sense if this bike project was intended more to be a video, and less about actually using it. The things I would have done differently were: Found a way to keep the pedals so that you can still pedal if you run out of battery. Used a thumb throttle instead of a servo tester. Used a VESC ESC because its current control method is so much more suitable to ebikes than the typical duty cycle control (it's a nightmare starting to turn on the electrical power if you are already moving with a duty cycle based ESC, it causes it to brake rather than accelerate). Add more heatsinking to the motor, it'll get quite hot trying to use it like a moped.

[@philipardvall1968]

Can someone explain why the motor dont stutters when there is no hall sensors? Without load just free spinning I understand that it works but when using it under load it must stutter.

[@yogeshnaik9276]

well done video, but how much kms it goes on a full charge, my office is 30 km and I want to now if you can put this motor in hub for me Thanks Yogesh..Goa

[@mattclark7941]

Hi please could you do a video on how you wire the motor it’s difficult to see on the video? 👍

[@jelteswinnen6865]

yea

[@rx-robo3405]

Its easy guys, just match the cable colour between bldc motor and universal brushless controller

[@awadsaeed5392]

Good project.. but please give more information about the part you use like the battery and the cre ..

[@circuitdotlt]

where can I buy such sprocket, mounted in place of brake disk?

[@Traderhood]

Great project. I wish there was more detail on how you altered winding of the motor.

[@MrJbrantley1]

Me too

[@tejassoni21]

Great to see first time who made Cannes in winding to increase the torque. I believe the it will increase the current draw of the battery and cause less run time. Just let me know does it affect battery run time compare to last set up. Thank you.

[@insidetechnology2745]

App ne konsi engineering kri hai plz tell me

[@andisuryowinarto5277]

[@ITSMYBSNLDINESH]

How many watts power consumes and cost of motor. Can you available in indian markets

[@yogeshnaik9276]

nice, i have suggeston, plase make a motor with paddles and cadens sensor and gear motor like those in abroad of bocsh or Yamaha you are already close

[@rugerist]

hello, what is the reference of the pinion, please.

[@milindambike9683]

What if I use ceiling fan motor instead of hoverboard motor??? What changes would I need to make???

[@samermardo431]

Hello dear. When can we get some more details on how you rewinded the coil of the motor and eliminating the hall sensors please?

[@klausbrinck2137]

No rewinding, simply from Star to Delta, gives √3-fold more speed, but equaly less torque. Would be cool, if he could switch back and forth between the 2 configs, so 2-gear e-motor...

[@IUbU]

@@klausbrinck2137 All right, so is there any point, to refurbish the moto inside, instead of setting up a simple mechanic bike gear to change between more speedy or torquey outcome?

[@klausbrinck2137]

@@IUbU 1st: You save electricity and so get higher range. 2nd: You don´t have to use yout legs, you use the motor after all... So, there is 2 points there already. And he doesn´t have 2 electric gears anyway, he just chose to switch to the 2nd gear permanently.

[@lovepreetsinghgill517]

Elimination of hall sensor is in e.s.c. not in motor.

[@imamit_07]

Can we use throttle like bike instead of this potentiometer...? I think that would look more realistic and cool...

[@-joo3033]

Realistic?

[@Факультет-с4ф]

Very cool bro 👍🏻 Super comfortable to watch.

[@dapure1718]

[@timothyhinton7513]

Can u tell me the brushless controller info please and batteries

[@ffss2989]

It's an interesting design, but you got the essence of a bike, which is the pedal of the bike! If the battery gets empty somewhere for any reason, it's no longer a bike.

[@carman1209]

I love it. I wish I had that bike. Great job and god bless you sir..

[@SIKHGT650]

Bhai brushless motor ki rewind batao kese krni h jaldi ...plzzzz

[@yakz9885]

You should get a 72v 60a kt controller and run this on 20s max. Reccomend looking on the endless sphere forums for ebike research. Great build though.

[@kailashsatokia3611]

Ajab gajab he by cycle

[@Alex-silva16]

how many watts does this 250w or 350w motor have

[@TheMcdrewb]

How did you put tension on the chain??? Looked like it went on real easy...meaning it would come off easy?? What am I missing??

[@luisrivera-pq7jd]

I have a radmini with a 750watt rear hub and 48v 14ah battery but is slow can you help to make it go faster

[@BattleHawkHeavy]

Nice build and vid, but one suggestion, you may want to consider putting a guard around the motor to prevent your pant leg from getting snagged.

[@nevillecreativitymentor]

Nice work .

[@abhishekgourav6144]

You did the conversion but what about more important stuff like mileage... obviously if you run out of battery mid way then that cycle will become a big metal frame with two fancy wheels as there are no pedals for manual riding..

[@cheeezz4077]

Very nice done ✅

[@anandkamath5785]

very good and quality conversion done...keep it up...

Hello DIY King, thanks for sharing. Just a quick question: can the xiao mi escooter motor also be used?

[@darexg]

yes. inside its exactly same motor

[@looking-beyond]

A small help if u can Convert cycle chain to a duplex chain Pl if possible

[@chuckeynewkirk199]

Fun video

[@edelbarcelon3321]

can you share me to increase the speed of hoverboard motor and the pcb board i want to build like what uou have done thanx more projects to come

[@DMonZ1988]

congratulations, this is super cool and very nicely done! i could be wrong, but couldn't you just have used a larger front sprocket instead of modifying the motor and getting custom pcbs?

[@solveit1304]

Exactly. Gear ratio is for high torque and slow rpm.

[@agnerruiz1502]

Can u make a video about how to connect the motor on parallel and connecting the circuit board this will help other ppl in other projects. I have a extra motor I ship to u if u need one.

[@jelteswinnen6865]
