If you're experiencing issues with your GT73 electric bike, you're not alone. Here are some common problems and their solutions to help you get back on the road quickly.
Throttle Response Delay
- Issue: Many riders notice a delay when they turn the throttle before the bike starts to move.
- Solution: This is not a malfunction but rather the bike's default acceleration curve designed for safety and smooth riding. If you prefer a more responsive throttle, consider adjusting the pedal assist or power mode settings via the bike's digital display. Increasing the power level from eco to sport mode can significantly enhance acceleration responsiveness.
Speed Limit Adjustments
- Issue: Some users find that their bike does not reach the claimed top speed of 37 mph, only achieving around 30 mph.
-
Solution: To unlock the speed limit, follow these steps:
- Press and hold the S key and the Power key simultaneously to enter P01.
- Use the S key to navigate and adjust settings.
- Press and hold both keys again to save your changes and exit.
If you want to set a maximum speed limit (like 28 mph) for safety, switch the mode to Eco, which will cap your speed accordingly. You may use the vide here as a guide for adjusting speed.
Throttle Not Working
- Issue: The throttle may not engage properly.
- Solution: Ensure that you are in power-assisted mode by pressing the power button three times in quick succession. If the throttle still does not work, check if the brake pads behind the vehicle are illuminated, as this can affect throttle functionality.
Shock Absorber Concerns
- Issue: Some riders report that the pre-installed spring shock feels weak and bottoms out frequently.
- Solution: The extra shock absorber included with your bike is an upgraded version. While it’s not mandatory to replace it, many users find that switching to this updated shock improves ride quality. If you choose to replace it, installation instructions are available online for your convenience.
Battery Charging Instructions
To charge your GT73 batteries effectively:
1. Turn Off Batteries: Ensure all batteries are switched off before charging.
2. Choose Charging Method:
- Option A: Remove batteries from the bike and connect them to the charger individually.
- Option B: Charge while batteries are attached to the bike by plugging in directly.
3. Connect Charger: Plug in the charger to a standard outlet and connect it to the battery charging port.
4. Monitor Charging: The charger LED will indicate charging status—red while charging and green when fully charged.
5. Secure Battery: After charging, ensure that protective caps are replaced on battery ports to prevent dirt and moisture ingress.
Error Codes
If you encounter error codes like E08, which indicates a motor phase line short circuit:
- Check for any visible damage to motor wires.
- If undamaged, disassemble the seat bag and unplug the three motor phase lines without disconnecting other connectors.
- Turn on the bike again to see if the error persists.
