5. Maintenance
Regular maintenance ensures the longevity and safe operation of your e-bike.
- Battery Care: Charge the battery regularly, even if not in use, to maintain its health. Store the battery in a cool, dry place away from direct sunlight and extreme temperatures. Avoid fully discharging the battery.

- Brakes: Regularly check brake pads for wear and ensure brake levers operate smoothly. Adjust or replace as needed.
- Chain and Gears: Keep the chain clean and lubricated. Inspect the Shimano 7-speed gears for smooth operation and adjust if shifting becomes rough.
- Frame and Fasteners: Periodically inspect the aluminum alloy frame for any signs of damage. Ensure all bolts, nuts, and quick-release mechanisms are tight and secure.
- Cleaning: Clean your e-bike with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components.
