This reliable and powerful 500W rear geared hub motor is a classic and effective solution for converting a standard bicycle into a high-performance e-bike. Designed for rear axle installation, it features a standard threaded interface for multi-speed spin-on freewheels. Thanks to its built-in planetary gear reduction system, the motor delivers outstanding torque from a standstill and confident hill-climbing capabilities while maintaining excellent energy efficiency.

Key Advantages:

• High 500W Power & Torque: The internal planetary gear mechanism multiplies the torque output efficiently. This ensures quick acceleration, effortless hill climbing, and reliable performance even under heavy loads or steep inclines.

• Standard Freewheel Compatibility: Equipped with a universal threaded mount, this motor easily accepts traditional spin-on freewheels (typically 6, 7, or 8 speeds), making it highly compatible with a wide range of affordable and widely available drivetrains.

• Excellent Drag-Free Coasting: The integrated freewheel clutch completely disconnects the internal gears when the motor is inactive. This allows you to pedal or coast just like a conventional bicycle with absolutely zero rolling resistance or drag.

• 36V & 48V Multi-Voltage Support: Operates seamlessly with both voltage standards, providing complete flexibility when choosing your battery and controller setups tailored to your specific speed and range needs.

• Optimal Weight Distribution: Rear-wheel placement ensures superior traction on various road surfaces, preventing wheel slippage during sudden starts or steep off-road climbs.
