⚠ This is an electric dirt bike (e-moto), not an e-bike
It's a high-voltage off-road motorcycle. Check the rider age in your bike's manual. Many states and cities treat these as off-road motorcycles, so check your state's off-road vehicle (OHV) rules before riding anywhere public, and always wear a helmet and protective gear.
Only do the safe checks on this page. The battery, motor, controller and high-voltage wiring are for trained technicians: never open them or unplug high-voltage connectors. For anything else, contact an authorized GOTRAX dealer. About e-moto codes on this site
Quick answer
E9 on the GOTRAX Fitz16 electric dirt bike means “Motor over-temperature protection.” Most likely cause: the motor or controller got too hot from hard or long riding. Try this first: let it cool down.
Gotrax's page words this as "over motor over-temperature protection".
Code meanings vary by brand. The same number can mean different things on different displays and controllers. Check your bike's manual to confirm.

Step-by-step checklist
Reset
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 Let it cool down Free Switch off and let the bike sit in the shade for at least 30 minutes. Overheating usually comes from long full-power riding, steep climbs or hot weather. Ride more gently once the code clears.
2 Switch off and restart Free Turn the bike off with its key or power switch, wait 30 seconds, then turn it back on. If the code clears, note what you were doing when it appeared, in case it comes back.
3 Write down the code and when it happens Free Take a photo of the display and note when the code appears: at switch-on, under hard acceleration, on climbs, in rain or while charging. Your dealer will ask for this.
4 Contact an authorized dealer Shop job If the code stays after these checks, stop riding and contact an authorized dealer for your brand. The battery, motor, controller and high-voltage wiring are for trained technicians only. Don't open them or unplug high-voltage connectors.
⚠ When to stop and get a shop
Electric dirt bikes run on high-voltage batteries and powerful motors, far stronger than most e-bikes. The battery, motor, controller and high-voltage cables are for trained technicians only: never open them or unplug high-voltage connectors. If these checks don't clear the code, contact an authorized dealer.
Anything inside the battery, the controller, the motor or the high-voltage wiring is a job for an authorized dealer.
