e-fat/e-cargo

S-Type RF Rear Hub Motor

The S-Type RF rear hub motor is designed for E-Cargo and E-Fat applications, offering a rated power of 500W-750W. It features  thread on 7-speed freewheel, a 190mm dropout, and a peak stall torque over 90Nm, ensuring strong performance on slopes and complex terrains. The motor weighs only 4.38kg. Equipped with HENTACH's patented plastic-steel gears-five times stronger than nylon gears-it supports motors rated above 1000W, where traditional nylon gears would wear out quickly under sustained torques above 100Nm.
