5. Maintenance

Regular maintenance ensures the longevity and safe operation of your electric bike.

5.1 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.
• Do not expose the battery to water or moisture. The battery has an IP5 waterproof level.

• Check tire pressure before each ride and inflate to the recommended PSI.
• Inspect tires for wear, punctures, or damage.

5.3 Brake System

• Regularly check brake pads for wear and replace them when necessary.
• Ensure brake levers are firm and responsive. If they feel spongy, the hydraulic system may need bleeding by a professional.

• Inspect gears and derailleur for proper alignment and function.

5.5 Suspension System

The TK300 features dual front and rear shock absorbers. Periodically inspect the suspension components for any signs of damage or leaks. Keep them clean from dirt and debris.

6. Troubleshooting

This section addresses common issues you might encounter with your Tomofree TK300 Electric Bike.

6.1 Bike Not Powering On

• Check Battery: Ensure the battery is fully charged and securely installed.

• Brake Pads: Inspect brake pads for wear. Replace if worn out.
