What maintenance is required for the Bosch system?

Troubleshooting

Motor not providing assistance

Check if the battery is charged and properly seated. Ensure the system is turned on and in an assist mode. Verify that the speed sensor is correctly positioned and free from obstructions. Consult the Bosch manual for further diagnostic steps.

Shifting is poor or inconsistent

Check the derailleur hanger for bends. Ensure the gear cable is not frayed or kinked. Re-adjust the rear derailleur indexing. For persistent issues, seek professional adjustment.

Suspension feels too harsh or bottoms out

Adjust the air pressure in the fork and rear shock to match your weight and riding style. Experiment with the rebound and compression settings on the RockShox components. For the rear shock, consider adjusting the leverage rate if needed.

Battery drains faster than expected

Ensure the battery is fully charged. Check for any unintended assist mode usage or prolonged idling. Reduce the assist level. For extended rides, consider the Power More system if compatible.
