If your FUELL Flluid 1 bike won't turn on even though both batteries are charged, check the following:

- Ensure the battery is turned on.
- Check if the battery contacts are clean.
- Check if the fuse in the battery is blown.
- Make sure the plug connection to the display is secure.
- Verify that the control panel/display is not defective.

If the display is on but there's no assist:

- Ensure the assist mode is not set to "0".
- Ensure the speed is not higher than 20/28 mph.
- Check if the battery is almost empty (flashing last bar).
- Look for error codes (e.g., 23, 24, 25) and fix the related issues.

Also, confirm that the magnetic disc's distance to the sensor is not over 3mm. If problems persist, turn the system off and on again.
