Speed or torque: how to choose
The same motor size often comes in two versions. The HIGH SPEED version spins faster and prioritizes top speed; the HIGH TORQUE version prioritizes torque for standing starts, hills, heavy riders, or loaded machines. The model number corresponds to the magnet length (75 mm for an MHT75): the larger it is, the more power the motor can handle.
The range goes from W50 and W60 motors up to the XHS100, with dedicated Weped FS versions and the RM290. The product sheets specify compatible machines, rims, and phase cable gauge. Motor ventilation is ordered separately.
