6. Maintenance
Regular maintenance ensures optimal performance and safety for your EUYBIKE F6.
General Care

Tire Pressure
Check tire pressure regularly. The recommended pressure for the 20" x 3.0" fat tires is typically between 20-30 PSI, but always refer to the sidewall of your tires for the exact range.
Brake Adjustment
Inspect brake pads and rotors for wear. Adjust brake levers for comfortable and effective stopping power. If you notice any grinding or reduced braking performance, consult a professional.
Chain Lubrication
Lubricate the chain every 100-150 miles or after riding in wet conditions. Use a bicycle-specific chain lubricant.
