I thought the video said it uses regenerative braking, so conventional brakes would be counterproductive. But I don't know how effective the regen braking is, compared to disc brakes, when you really need to stop.Jay H said:... I wonder if they can mount disc rotors on them too... Jay
http://auto.howstuffworks.com/auto-parts/brakes/brake-types/regenerative-braking.htmIt's a balance. Regen braking works by turning the wheel into an generator, using the kinetic energy to charge the battery, and slow you down. Pure friction brake loses all the energy to heat. Pure regen apparently isn't effective enough at some speeds to be the sole brake.Jay H said:I believe regenerative braking means that when braking, the kinetic energy is used to recharge the internal batteries, NOT that it replaces whatever brake mechnism it has.. I didn't look into it enough whether it uses a special hub for the motor to drive.Jay
