6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your BURCHDA R7PRO.
6.1 Battery Care
- Charging: Charge the battery fully after each ride. Avoid completely draining the battery.
- Storage: If storing the bike for an extended period, charge the battery to 50-70% and store it in a cool, dry place. Recharge every 1-2 months to prevent deep discharge.
- Cleaning: Wipe the battery casing with a dry cloth. Do not use water or solvents.
6.2 Tires
- Tire Pressure: Check tire pressure before each ride. Maintain the recommended pressure (typically indicated on the tire sidewall) for optimal performance and safety. For 20x4.0 inch fat tires, this is usually lower than standard bike tires.
- Inspection: Regularly inspect tires for wear, cuts, or embedded objects.
6.3 Brakes
- Brake Pad Wear: Check brake pads regularly for wear. Replace them when they become thin.
- Brake Fluid: Hydraulic brakes require periodic fluid checks and bleeding. If you notice a spongy feel or reduced braking power, consult a qualified bicycle mechanic.
6.4 General Cleaning and Lubrication
- Cleaning: Clean the bicycle regularly with a damp cloth and mild soap. Avoid high-pressure washing, especially near electrical components.
- Lubrication: Lubricate the chain and other moving parts (e.g., derailleur pivots) periodically with bicycle-specific lubricant.
