BRD’s first products are the RedShift MX (Motocross) and SM (Supermoto) bikes. At their heart are custom, three-phase, PMAC, high-voltage electric motors, weighing about 10 pounds. Such a motor has rare earth-magnets on its rotor, with stationary coils to spin them. A high-speed motor like this can make plenty of power, with its main limitations being thermal. Having the coils on the outside, rather than an inductive rotor, allows ready cooling. In this case, the motor fits into a special casting that serves both to route liquid-cooling to the coils and also serves as the rear structure of the chassis.
