7. Maintenance

Regular maintenance is crucial for the safe, efficient, and long-lasting operation of your JANSNO X50 Electric Bike.

7.1 Daily Checks (Before Each Ride)

• Tires: Check tire pressure. Ensure tires are inflated to the recommended PSI (found on the tire sidewall). Inspect for any cuts, punctures, or excessive wear.
• Brakes: Squeeze both brake levers to ensure they are firm and responsive. Check that brake pads are not excessively worn and that rotors are clean.
• Fasteners: Quickly check all visible nuts, bolts, and quick releases (e.g., seat post, wheels, handlebars) to ensure they are tight and secure.
• Battery: Confirm the battery is fully charged and securely locked into its compartment.

7.2 Periodic Maintenance (Monthly/Quarterly)

• Chain: Clean and lubricate the chain regularly (e.g., every 100-200 miles or monthly, depending on use and conditions) to prevent rust and ensure smooth gear changes.
• Brake System: Inspect brake cables and housing for wear or fraying. Adjust brake tension as needed. For hydraulic brakes, check fluid levels and consider professional bleeding if performance degrades.
• Suspension: Clean the stanchions of the front fork and rear shock. Inspect for any leaks or damage.
• Electrical Connections: Periodically check all visible electrical connections for corrosion or looseness. Ensure they are clean and dry.
• General Cleaning: Clean the bike with a damp cloth and mild soap. Avoid using high-pressure washers directly on electrical components, bearings, or seals.
