Hub Motors for Personal Electric Vehicles Click to see hub motor details. Useful Info: Torque (in N*m) = 9.55 * Power (in watts) / Speed (in rpm) It looks big and clunky, but it's optimized for weight reduction with better construction and thin walls.

My priorities are relatively lightweight, would like to have ~1500w acceleration available, but would use that rarely, low-maintenance, torque sensor (Sempu looks best here) and will generally commute on the fairly flat bike path so not a lot of braking. I have a geared hub motor running 52v 20a , and tops out at about 28mph on a 700 x 38c tire. I'd like to get a little more speed out of it, but can't go too big on the torque.

6'. However, this is only possible on electric bikes that have larger motors with no gears.
