Velotric e-bikes on models like Discover 2, Nomad 2, Nomad 2X, Breeze 1, Summit 1, Fold 1 Plus, Triker, T1 ST Plus, Discover 3, Discover M, Summit 2, and GoMad display error codes via an integrated display/controller system. Cease operation immediately upon any error code--do not ride. Check official model-specific troubleshooting, such as connector disconnection tests or brake lever adjustments, then contact Velotric support directly for resolution or parts. Non-Velotric batteries or external supplies can trigger overvoltage errors; avoid them.
This helps Velotric owners safely verify basic issues before professional service.

- Power on after each disconnection.
- If the error clears with a specific connector off, replace the component linked to that connector.

Specific Fixes for Frequent Errors
For listed models, official steps include:
- Combined E02/E03/E04: If any two appear together, replace the display first.
- Brake lever errors: On the faulty lever, turn the grip distance adjustment screw clockwise until 2-3 threads are exposed.
- Controller calibration failure: If calibration is not possible, replace the controller.
Confirm your model and follow the Velotric guide exactly.
When to Stop and Escalate
Stop troubleshooting and contact Velotric if:
- Error persists after checks.

- Any uncertainty on model or steps.
