6. Maintenance
Regular maintenance ensures the longevity and safe operation of your Qlife Triker Plus.
- Tire Pressure: Check tire pressure regularly (recommended: 20-30 PSI for fat tires). Proper inflation improves ride quality and range.
- Brake Inspection: Periodically check brake pads for wear and brake cables for tension. Adjust or replace as needed.
- Chain Lubrication: Keep the chain clean and lubricated to prevent rust and ensure smooth operation.
- Fastener Check: Regularly inspect all bolts, nuts, and quick releases to ensure they are tight and secure.
- Cleaning: Clean the tricycle with a damp cloth. Avoid high-pressure washing directly on electrical components. The IP54 waterproof rating protects against splashes, but not submersion.
- Battery Care: Store the battery in a cool, dry place. If storing for extended periods, charge it to 50-70% every 2-3 months.
