E-bike display
The display shows speed, battery and assist level and often works as the power switch. A replacement must match your model and your controller's protocol.

Battery and electrical safety. Lithium-ion batteries can catch fire if they're damaged or charged wrong. Never open a battery pack, and stop using any battery that's swollen, hot, wet or smells burnt. Every edit to this page is checked by a second person before it goes live.
The display is the screen and button pad on the handlebar. It shows speed, battery level and assist level, and on many bikes it is also where error codes appear. Grin Technologies notes that displays use no standard communication protocol, so a display is usually tied to one controller (Grin, e-bike parts explained).
A display is matched to your controller and plugs in at its handlebar cable. Never open the display or cut and splice its cable. Remove the battery before you unplug it, and if the bike still won't power up, find a shop.
What it's used for
The usual reasons to replace one are a cracked or water-damaged screen, dead buttons, or a display that stays blank while the battery, plugs and cable check out. Start with Display blank or flickering and E-bike won't turn on, and read any code with E-bike error codes before you order.
What to look for
- Your model. Velotric lists its Summit 1 display as compatible with the Summit 1 only (Velotric). Aventon sells several different displays, including the BC 280, BC147 and BC201 (Aventon), so match the one on your bike.
- Throttle or no throttle. Ride1Up sells separate throttle and non-throttle displays for the Roadster v2 (Ride1Up Roadster parts).
- The controller's protocol. For Bafang mid-drive kits, California Ebike sells the same VD04 color display in a UART version and a CANBUS version (California Ebike displays). The display has to match the protocol your controller uses. Grin lists I2C, CAN, LIN and UART as protocols in use (Grin).
- Plug and mount. Compare the plug and handlebar clamp with your old display. California Ebike sells Bafang display brackets and button pads separately (California Ebike displays).
- Pairing. Some bikes need a new display or controller set up in the maker's app, as some Aventon models do (Electric Kicks help center). Keep firmware current with Update e-bike firmware.
