Awesome project! Would you mind if you could link me to a moter that is sutable to be used?
Firstly Thank-You! I have been wanting an E-bike for some time due to a leg partial disability, but they are very expensive. I am going to try to build one like your design. Thanks again!!
great work../... but when its 300 watt 24 volt motor then it should draw 12.5 amps not 4 to 9.... if it is drawing that then theres a problem with the motor it isnt giving its perfect efficiency....
can u tell me the measurements of that wheel used for motor
your video seems to show that there's no drag / loss worth mentioning when the electric motor is off.... That's interesting to know! (I would have thought the motor would drag on the wheel when not powered :)

thanks
How did you wire it? Did you just connect the switch between the motor and the batteries? Also, did it not work well in the rain due to the circuit not being waterproof? Or was it due to the friction motor setup itself?
I get it, functionality over form, and its pretty cool but my god man did you use a hatchet to cut the metal? ... my other thought is you could setup a sort of deadman switch, so that when you apply the brakes it disengages the motor.
Great job
I want to make one sweet ride to work.
how do you recharge the battery?
Well its easy science I doubt get the Dan point why did you get so many likes I mean any smart intelligent that' dosent work in a burger shop should understand how easy it is
