This kit turns a 28-inch rear-wheel bike into an electric one with a 1000W brushless hub motor, a prebuilt 28-inch rear wheel with a 700-38C tire, and an LCD handlebar panel. The panel shows speed, trip and total distance, and battery level, and the assist can be set to 8, 15, 21, 27.5 or 35.5 mph. A pedal-assist sensor switches between assisted pedaling and full-electric moped mode. It suits riders with a 28-inch frame who already own a 48V battery and want a rear-hub build without buying a whole e-bike; the trade-offs are a heavy rear wheel, a battery not included, and a kit that needs real mechanical and wiring work.

This conversion kit turns a bike with a 28-inch wheel into an electric bike. It includes a 1000W brushless hub motor built into a 28-inch rear wheel with a 700-38C tire. The kit also has the wiring, custom handles and an LCD control panel. A 48V battery is needed and is not included.
The LCD panel shows speed, session and total distance, and battery level. It switches between 20, 40, 60, 80 and 100% of top speed. The motor is preset to follow public speed limits. It can be shifted between 8, 15, 21, 27.5 and 35.5 mph, with a top speed of 35.5 mph (57 km/h). The control system can limit the top speed or block the 2 fastest settings.
A pedal assist sensor lets the rider switch between throttle control, cruise control and pedal assist. A 7-speed 14-28 freewheel is included for manual pedaling. Cable ties and a cable cover keep the wiring tidy. Step-by-step instructions are included.
