Interesting that they state '300-Wh/kg' which sort of implies the battery could be only 0.5kg offering 150Wh or maybe 600Wh if 2Kg but I'm guessing the battery will be low capacity to suit the bike type. I think most consumers just want to know the Wh without any link to wattage to weight ratio. Seems like manipulative marketing.

Not the smallest ebike motor. People have been using all sorts of R/C motors to power their bikes for as long as I can remember. Some in friction drives and some driving a massive sprocket or reduction system. This one is 185g and can do over 500w:

PROPDRIVE v2 3548 1100KV Brushless Outrunner Motor

PROPDRIVE v2 motors are designed to perform right out of the box with tight windings, smooth bearings, correctly rated magnets, precision cut stator and balanced rotors.
