HT MINI 250W Front Hub Motor

The HT MINI front hub motor is designed specifically for urban bicycles and is one of the smallest outer rotor hub motors on the market. With its compact and lightweight structure, it weighs only 1.95kg but can achieve a rated power of 220W, with a torque of over 30Nm. Its rated power can reach 250W, and the stall torque can reach 40Nm. Additionally, the motor features an outer rotor structure, which, compared to smaller inner rotor motors, has less error accumulation, higher structural strength and stability, and is more durable.
