General Care
- Regularly inspect the bike for any loose parts, especially after riding on rough terrain.
- Keep the bike clean and dry. Use a damp cloth to wipe down surfaces; avoid high-pressure washing.

- Check tire pressure before each ride and inflate to the recommended PSI.

Troubleshooting
Here are some common issues and their potential solutions:
- Bike not powering on: Check battery connection, ensure battery is fully charged, and verify the key is in the 'ON' position.
- Motor not engaging: Ensure you are in an electric or pedal-assist mode. Check brake levers; some systems prevent motor engagement if brakes are applied.
- Reduced range: The battery may not be fully charged, or riding conditions (e.g., hills, heavy load, strong headwinds) may reduce range. Check tire pressure.
- Brake issues: Inspect brake pads for wear and replace if necessary. Ensure brake cables are properly tensioned. If issues persist, consult a qualified bicycle technician.
- Unusual noises: Inspect the chain, wheels, and suspension for any obstructions or loose components. Lubricate moving parts as needed.
