NBPower 72V 8000W QS273 Fat Kit Fardriver (24×4")
Options
NBPower 72V 8000W electric fat/snow-bike conversion kit built around a genuine QS Motor QS273 40H V3 hub motor (~250 N·m) pre-laced into a 24×4" fat rim (150mm dropout, 80mm rim default). This is the Fardriver-controller permutation: a Fardriver ND72850 FOC sine-wave controller (SIAECOSYS LIN/CAN, regen, field-weakening, IP67), a SIAECOSYS DKD LCD display, a full-twist throttle, a torque arm, and a single-speed flywheel. 48–72V, up to ~130 km/h on the 3.5T winding (5T high-torque also offered). Batteryless conversion kit.
