Tire Pressure
Regularly check tire pressure to ensure it is within the recommended range for optimal performance and safety. Proper inflation helps prevent punctures and improves ride quality.
Brake System
Inspect brake pads and rotors for wear. Clean them regularly to maintain effective braking. If you notice reduced braking performance, have the system inspected by a qualified technician.
General Cleaning
Clean your e-bike with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components. Ensure the bike is dry before storage or next use.
Troubleshooting Common Issues
- Bike not powering on: Ensure the battery is fully charged and properly seated. Check all electrical connections for looseness.
- Motor not assisting: Verify the PAS level is set above zero. Check if the brake levers are fully released, as some systems cut motor power when brakes are applied.
- Unusual noises: Inspect for loose components, rubbing brakes, or chain issues. Lubricate the chain regularly.
- Reduced range: This can be due to low tire pressure, riding in high assist modes, or riding against strong headwinds. Ensure proper tire inflation and consider lower assist levels for longer rides.
