A conversion kit that turns a 20-inch front wheel into a powered one: a 1000W 48V brushless hub motor laced into a 3 1/4-inch aluminum rim, plus controller, twist throttle, brake levers, harness and pedal-assist sensor. It is built for fat-tire bikes with a 20 x 4 tire and a 135 mm front dropout, and the motor is rated to about 45 km/h with efficiency above 80%. The tire is not included, and the kit expects a 48V lead-acid pack of roughly 17-20Ah. It suits DIY builders who want front-wheel drive and already own a compatible fat-tire frame; it is a bare components kit, not a finished e-bike, so wiring and dropout fit are on the buyer.

This kit turns a bicycle into an electric bike with a 20-inch front wheel built around a 1000W, 48V brushless hub motor. The wheel has a 3 1/4 in aluminum rim for fat tires. Top speed is up to 45 km/h, and motor efficiency is more than 80%.
A twist throttle starts the motor when you twist the grip. It has 3 indicators that show battery status. The pedal assist system (PAS) lets you ride without using the throttle, which can reduce fatigue on long trips.
The kit works with bicycles and snow bikes, not tricycles or tractors. The tire and battery are not included. Wear a helmet when riding. Using the bike in rain is not recommended.
