72V5000W Hub Motor Kit for Fat Bike

Best for riders who want maximum rear-wheel power on fat bikes. This kit uses a 72V 5000W controller with a current of 80A and a 20″x4.0″ rear wheel. It is compatible with fat-bike rims that use 175mm dropouts and laced wheels with robust spokes. The package includes a left pedal sensor, a 1T4 cable harness, a thumb throttle, electric brake integration, and a controller bag. Battery integration requires a separate 72V BMS rated for 85A. Choose this if you need aggressive acceleration and off-road capability, and you are comfortable with a high-power wiring setup. A potential limitation is the need to source a compatible 72V battery and BMS separately, which adds to the overall install effort.
Best for:
- Fat-bike riders seeking top-end power and quick acceleration.
- Builders who want a rear-drive setup with a wide 20×4.0″ tire compatibility.

Batteries are not included. The system offers nine speed levels and cruise control for comfortable commuting. It is well-suited for riders seeking a reliable, all-in-one conversion with straightforward installation. A caveat is that battery availability is separate and the overall weight may be higher than simpler kits.
Best for:
- Commuters who want a predictable, multi-speed ride with clear LCD feedback.

It includes a sine wave controller and a controller bag, along with a TFT UKC1 color display. Users should plan for battery integration separately. This option is suitable for those who want a mid-width, reliable performance setup with clear display readouts. A constraint to consider is the potential need for frame compatibility checks due to dropout spacing.

Buying Guide
What should you check before buying a 72V ebike conversion kit?
- Bike compatibility: Confirm dropout spacing, wheel size, and tire width match the kit’s motor and mounting hardware.
- Power needs: Higher Wattage means faster acceleration and steeper climbs, but also increases weight and battery demands.
- Battery and BMS: Many kits require a separate 72V battery and battery management system (BMS). Ensure the BMS rating aligns with the kit’s current draw.
- Controller features: Look for pedal assist support, throttle options, regenerative braking, and safety protections.
- Display and controls: LCD or TFT displays help monitor speed, distance, battery life, and settings. Check readability in sunlight.
- Weight and installation effort: Heavier kits may require professional installation, especially on fat bikes or unconventional frames.
- Maintenance and parts availability: Prefer kits with widely available spare parts and clear manuals.
