- Brakes: Regularly check brake pads for wear and ensure brake levers provide firm, responsive stopping power. Adjust cables as needed.
- Chain: Keep the chain clean and lubricated to ensure smooth shifting and prevent rust.
- Battery: Charge the battery regularly, even when not in use, to maintain its health. Store in a cool, dry place. Avoid fully discharging the battery.
- Fasteners: Periodically check all bolts and nuts for tightness, especially on critical components like wheels, handlebars, and seat post.
- Cleaning: Clean the bike with a damp cloth. Avoid high-pressure washing directly on electrical components.
