PARTS FOR EVERY E-BIKE
Controllers, displays, motors and sensors for e-bikes of every brand — including bikes whose maker is long gone. We help you identify the right part, then show you how to fit it.
Controllers & Displays
Controllers and displays are supplied as factory-paired, tested sets. Communication protocols differ between brands — a display bought on its own often will not talk to your controller, even when the plug fits. Buying the pair removes that risk.
Motors & Wheels
Hub motors and complete motor wheels in 20-inch and 26-inch, fat and standard tire widths. Measure your dropout width before ordering: 135mm is standard, fat-tire frames use 170mm or 190mm, and those two are not interchangeable.
Sensors & Wiring
Cadence sensors, throttles, brake levers and wiring harnesses. Before you replace a sensor, check the assist level, the brake levers and the magnet gap — around 80% of pedal-assist faults turn out not to need a new part at all.
We Check the Fit First
Send us four photos and we will confirm the part fits your bike before you order.
