6. Maintenance
Regular maintenance ensures the longevity and safe operation of your tricycle.
- Tires: Maintain recommended tire pressure (check tire sidewall for specific PSI). Inspect tires regularly for wear and punctures. The 20" x 4.0" fat tires provide excellent traction.
- Brakes: Regularly check brake pads for wear and ensure brake levers engage smoothly. Adjust as needed. The tricycle features disc brakes for reliable stopping power.
- Battery Care: Store the battery in a cool, dry place. Charge it regularly, even if not in use, to maintain battery health. Avoid fully discharging the battery.
- Cleaning: Clean the tricycle with a damp cloth. Avoid high-pressure washing directly on electrical components. The tricycle has an IPX5 water resistance rating, meaning it can withstand splashes but not submersion.
- Fasteners: Periodically check all bolts, nuts, and quick releases for tightness.
- Chain: Keep the chain clean and lubricated for smooth operation.
