Gotrax e-bikes with a code-capable display use one of three error-code systems: E-numbers such as E07, "ERROR" plus a two-digit number such as 22, or hex codes such as 0x24 on the Mustang. The same number can mean different things in each, so first work out which one your bike uses. This guide covers e-bikes only, not Gotrax scooters, and is based on Gotrax's troubleshooting page and user manuals, read on November 2, 2026.
One instruction from Gotrax covers all of them: "Should you see any of these error codes turn off your electric bike and DO NOT RIDE it and contact GOTRAX Customer Service." If your bike is still covered by Gotrax, contact them before you open anything up.
Which family does your bike use?
- LED display only (EBE1, Alpha, Emerge, Endura, Traveler): Gotrax says these models "cannot show error codes" and asks owners to file a claim.
- E-numbers (EBE2, EBE4): E02 to E13.
- ERROR 21 to 30 (F-series): Gotrax's web page lists Errors 22, 23, 24, 25 and 30 for the F1, F2 and F5; the F1, F2 and F3 V2 manuals add Error 21.
- Hex codes (Mustang): 0x21 to 0x34.
EBE2 and EBE4: E02 to E13
A "0" on the display means normal status. Gotrax lists these codes and fixes:
- E02, brake: "Adjust your brake calipers so that they operate effectively."
- E03, power assist sensor failure: "Change speed settings or gear. If still showing error code, contact Customer Support for assistance."
- E06, cell under voltage: replace the battery.
- E07, motor failure: replace the motor or motor wheel assembly.
- E08, handlebar failure: the fix reads "Replace Handlebars." The page doesn't say which handlebar part it means, so ask Gotrax before you buy anything.
- E09, controller failure: replace the controller.
- E10, E11, E12 (communication receive, communication send, BMS communication): Gotrax calls these "an internal issue" and says the bike "should be sent back for repair."
- E13, headlight failure: replace the headlight.
F-series: ERROR 21 to 30
On these bikes the display shows "ERROR" with a two-digit code, and the F1 V2 manual says the bike "will not be able to continue to operate" until the fault is resolved. The V2 manuals give a cable check first, then a part swap:
- 21, motor current failure: check the motor connection cable; if it is normal, replace the motor.
- 22, throttle abnormal: check the throttle connection cable; if it is normal, replace the throttle.
- 23, motor phase line failure: check the motor connection cable first, then replace the motor.
- 24, motor hall signal abnormal: check the motor connection cable, then replace the motor.
- 25, brake failure: before powering on, check that the brake levers have returned fully and that their cables are normal; if both are fine, replace the brake levers.
- 30, display communication failure: check the cable between the display and the controller; if nothing is wrong, replace the display.
One exception: the Alpine manual pairs E21 "Current Anomaly" with a throttle (accelerator) check and E22 "Throttle Fault" with a motor check, the reverse of the V2 manuals and of Gotrax's web page. We follow the V2 manuals; the Alpine table looks like a layout mistake to us, but Gotrax hasn't said so.
These meanings line up with the 21-to-30 error code family many brands share. Gotrax's manuals don't name the maker of the controller or display, though, so a matching code list doesn't mean an aftermarket part will plug in and work.
Before you replace a motor for Error 23 or 24, a hall sensor test can show whether the sensors inside it still respond. For Error 22, a multimeter throttle test takes about ten minutes. For Error 25, see how a brake cut-off sensor can stop the motor.
Mustang: hex codes 0x21 to 0x34
The Mustang manual uses its own table, and its numbers don't mean the same as the F-series codes:
- 0x21: motor Hall sensor signal line fault
- 0x22: throttle fault
- 0x23: controller fault
- 0x24: under-voltage protection
- 0x25: motor phase wire fault
- 0x30: communication fault
- 0x31: power button stuck
- 0x34: walk assist button stuck
So 24 on an F-series display points to the motor's hall signal, while 0x24 on a Mustang means under-voltage protection. The manual gives no repair steps and points owners to Gotrax support. For 0x31 and 0x34, check that the buttons spring back first.
Before you buy a part
- Note the exact code and model, including whether it's a V2.
- Switch the bike off, then unplug and reseat the connector for the part the code points to. Look for bent pins, water or corrosion.
- Use our e-bike repair online page to narrow the fault to one system before you order anything.
We don't list any RideRow part as a confirmed fit for Gotrax bikes. If you are thinking about a non-Gotrax display, remember that the display and controller have to use the same protocol; see why e-bike displays aren't interchangeable.
