EA7 Error on Velotric

In plain English

Too much current flowed through the controller. Wiring shorts, water, a seized or dragging wheel, or a motor fault can cause it. Bafang's manual sends this one to your retailer, so do the free checks and then see a shop.

Work from the top. Steps go from free and easy to shop jobs. Switch the bike off before touching any connector. Tick each step as you go. Your progress is saved on this device.

1. 1Turn it off and on againFree Switch the display off, wait 30 seconds, then switch it back on. If the code clears, note what you were doing when it appeared, in case it comes back.
2. 2Check that the wheels spin freelyFree Lift each wheel and spin it by hand. Grinding, dragging or a rubbing brake makes the motor work harder.
3. 3Look over the motor cableFree Follow the cable from the motor along the frame. On hub motors, look closely where it leaves the axle: it often gets pinched when the wheel is removed or crushed when the bike falls. Look for cuts, kinks or bare wire.
4. 4Dry the bike out if it got wetModerate If the problem started after rain or washing, remove the battery and leave the bike somewhere warm and dry for 24 to 48 hours, then test again. Don't use a heat gun or put the bike next to a heater.
5. 5Ask a Bafang dealer to read the faultShop job Bafang dealers have a diagnostic tool that reads detailed fault data and can update firmware. It often pins down internal faults quickly.
