Question Not sure how, but I know this is possible.


Ok so I am working on an ebike project, and right now I am attempting to replicate a homemade friction drive which basically is just an electric motor with a spindle on it that will rub against the back tire, so that whenever the motor spins the spindle spins with it which moves the bicycle wheel. Also, here's the tricky part, the spindle will only work in one direction. Such that if the motor is off, the wheel can freely move and freely spin the spindle without turning the motor. Kind of like how a freewheel works on a bike.

Does that make sense?

If it does, can you help me make one?

I have this motor:
Electric Bike Scooter 24V250W Motor, Engine Brush Motor (MY1016) - China Electric Motor,Brush Motor

It's shaft is a D-bore, but there is about 1/2" of 5/16" sized threading on it.

What parts do I need to get and in what order do I need to assemble them in so that I can achieve the above?

Thanks so much,

Just stopping thru here. The motor you linked to is a chain drive motor. Interesting site. Did you check with them or look thru their site for the part you need. They have a lot of electric bike products.

I've seen a similar idea to what you are talking about but a direct drive part. Meaning that when the electric drive was needed the motor was spring loaded and held against the tire. When not needed the motor was swung away from the tire. A one way clutch system like you are looking for will be fairly complicated.
