I'd like to buy an ebike or to fit a 750W Bafang to a bike, probably by June or July. My ideal spec on the bike side is to have a belt drive, an internal gear hub or NuVinci, and hydraulic disc break. I hope the bike to look modest and minimalistic. And, of course, it should not be too expansive! I have a bike with a belt drive and Nuvinci, which is really great–clean, no maintenance, no grease!, and smooth–but has a unusual bottom bracket incompatible for Bafang.
