HT MINI2 Cassette Rear Hub Motor

The HT MINI2 cassette hub motor is designed for city and road bikes, making it the smallest external rotor hub geared motor on the market. Compatible with 36V/48V, and weighs only 2.03kg (with cassette) or 1.8kg (thread on), the patented plastic-steel gear ensures a lightweight riding experience. The motor offers a rated power of 220W with over 30Nm of torque, reaching up to 250W and 40Nm of stall torque. Its external rotor design reduces cumulative errors, enhancing strength and durability compared to the inner rotor design.

WHAT SETS US APART
  • The motor has an outer diameter of 85mm, and can be used with a 7-speed rotary flywheel (weighing only 1.8kg) and a 10-speed cassette flywheel (weighing 2.03kg). It is the smallest outer rotor motor with a stall torque of up to 30NM. A ebike partner.

  • Patented plastic steel gear: 5 times the torque of nylon gear; life span greater than 40,000 kilometers; lower after-sales

  • Outer rotor motor: more stable structure and lower failure rate than inner rotor
