Our Verdict
The BAFANG 48V 1000W Rear Hub Motor is a purpose-built electric bike conversion kit targeting 20-inch and 26-inch fat tire frames with 175mm rear dropouts and disc brakes. Operating on a 48V system with 1000W peak output and 85N.m of torque, this motor produces enough wattage to sustain speeds up to 26 mph and handle grades exceeding 20%, plus soft-surface terrain like sand beaches and packed snow trails.
At $337.66, the BAFANG 48V 1000W kit costs 3–5x less than a comparable complete fat tire e-bike at the same wattage — a meaningful budget advantage for riders who already own a compatible frame. The kit ships with a pedal assist sensor (PAS) supporting multiple assist levels, so riders can dial in how much of the 1000W output they actually use, directly affecting battery range. An optional digital LCD display can be added to monitor speed, trip distance, and real-time battery charge state. Range depends entirely on the 48V battery you source separately: a 48V 15Ah pack (720Wh) typically delivers 30–50 miles of pedal-assisted range; a 48V 20Ah pack (960Wh) stretches that to 40–65 miles depending on rider weight and terrain.
The BAFANG 48V 1000W Rear Hub Motor kit suits off-road riders and commuters who want high-wattage electric assistance without replacing a frame they already own. The cost-per-mile economics are strong once total build cost is accounted for, but total spend rises to $490–$640 once a 48V battery pack is added. Installation involves lacing the motor hub into your existing rear rim and routing the controller wiring — a process that takes 2–4 hours for an experienced mechanic. No UL certification is included, which is a notable gap for safety-focused buyers.
What We Like
- 1000W peak motor with 85N.m torque sustains speeds up to 26 mph and handles grades above 20% on sand, snow, and trail surfaces
- At $337.66, the BAFANG 48V 1000W kit costs 3–5x less than a comparable complete fat tire e-bike at equivalent wattage

- Multi-level PAS sensor lets riders control how much of the 1000W output is used per pedal stroke, extending battery range on a 48V pack
- Optional digital LCD display adds real-time speed, odometer, and battery charge readout without requiring additional mechanical modifications
What Could Be Better
- Battery sold separately — a 48V 15Ah pack adds $150–$300, pushing total build cost to $490–$640 before accessories
- No lights included; a compliant front and rear light set adds another $20–$50 to the total budget
- Not UL certified, meaning no third-party electrical safety standard has been independently verified on this 48V kit
- Installation requires lacing the motor hub into your rear rim and wiring the controller — typically 2–4 hours for an experienced mechanic, longer for beginners
- Only compatible with bikes featuring 175mm rear dropouts and disc brakes, excluding most standard road, hybrid, and hardtail mountain frames
