Designed to pair with various wheel sizes from 16” to 700C, this 48V 750W motor emphasizes robust performance for fat bikes. It utilizes steel forging to improve longevity and reliability, enabling confident rides across diverse terrains.
Powallon 750W Rear Wheel Kit — 20/26 x 4.0

Powallon’s rear wheel replacement kit ships pre-assembled with a BAFANG G062 750W motor. It fits 20 or 26 x 4.0 inch fat-bike wheels with 175mm hub spacing (O.L.D.), delivering solid torque for hill climbs and versatile riding across terrain and weather conditions.
Buying Guide: Key Purchase Considerations
- Power and torque: Most 750W motors target strong torque for hills and off-road riding. Look for torque figures (Nm) and sustained power ratings to match your terrain needs.
- Wheel compatibility: Fat bikes use wide rims and varied O.L.D. spacing. Confirm hub width, dropout compatibility (e.g., 184-190mm), and wheel size support before purchase.
- Durability and materials: Aluminum vs. steel forging affects weight and heat dissipation. Forged steel hubs tend to offer higher ruggedness for trail use.
- Weather resistance: IP65 or higher ratings help ensure performance in rain and dust. Consider sealing and component quality for daily commuting.
- Maintenance and upgrades: Some motors are simpler to replace or upgrade (rear wheel versus complete hub). Check compatibility with existing drivetrain, brakes, and disc brake standards.
- Installation and compatibility: Verify spacings (e.g., 170 mm or 175 mm O.L.D.), rear derailleur compatibility, and whether a replacement hub integrates with your current chainring and freewheel setup.
- Warranty and support: Look for manufacturer documentation and warranty coverage, especially for high-use off-road configurations.
- System integration: If pairing with a specific controller or battery, ensure voltage (48V) and connector types match your existing electrical system.
When evaluating options, compare motor efficiency, heat management, and compatibility with your bike’s frame geometry. For fat bikes, emphasis on wide compatibility, rugged construction, and reliable weather sealing tends to yield the best balance of performance and durability across varied riding conditions.
