QS Motor QS205 50H V3 5000W 4T Bicycle Hub (20")
QS205 50H V3-pattern direct-drive hub motor, 5000W rated, 4T winding, pre-laced into a 20" bicycle rim (150mm dropout). 16 pole pairs, aluminium core, 50mm magnet, KTY83 temp probe, dual hall, disc brake, 36-spoke. Sold by NBPower as 'NBpower/QS205 50H V3'; consistent with a genuine QS205 50H V3 but not independently verified as QS-produced (units stamped 'NBP WP50H'). Winding sets torque-per-amp and top speed (3T fastest ~1020rpm … 5T highest-torque ~650rpm); peak torque is a current-limited envelope (~170-180 N·m at 3kW/80A → 200-220+ N·m at 5kW/100A+).
In brief: 5000W direct drive rear hub motor. 20" wheel. Fits 150.0mm dropout. 48–96V rated. Disc brake compatible.
