Been working on this off and on. Biggest problem other than money is doing it in a 2nd floor apartment with no elevator. Urgh.. This is a Migargi frame with a 1500w hub motor laced into a 24 x 4.5 wheel. The front is a 26 x 3. There is a 203mm front rotor and a cable actuated hyd brake. One side...
Could also look at the Bafang mid drive. Have what ever gear ratio without too much trouble. Just be careful, the torque can be brutal on you drivetrain.
Better shot. 2nd-floor Apartment got to work with the space I have. Side boxes have a battery in one and a controller in the other, with storage space to spare.
Got ahold of a Scott AT4-Pro handlebar, and figured I needed to build a bike around it. Yes a Chinese frame, but cheaper than anywhere else.
Got great plans, just need the money.
