NBPower 72V 8000W QS273 Moto Kit Fardriver (17")

NBPower 72V 8000W electric-motorcycle conversion kit built around a genuine QS Motor QS273 40H V3 hub motor — the largest spoke-laced QS hub (~250 N·m) — pre-laced into a 17" moped rim (150mm dropout). 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.
