Maintenance Tips
- Keep bike dry; avoid rain exposure, puddles, and pressure washing to protect electronics
- Wipe frame, wheels, and drivetrain after every ride to remove dust and dirt buildup
- Regularly check and tighten bolts (frame, rack, stem, axle) due to vibration
- Inspect brakes frequently; adjust or bleed if braking feels weak or noisy
- Check tires for wear, punctures, and maintain correct pressure for safety and range
- Keep chain clean, lubricated, and properly tensioned for smooth power delivery
- Avoid overloading beyond rated cargo/payload to protect motor and frame
- Battery care: keep between ~20–80% for daily use; store at ~50–60% for long periods
- Recharge at least once per month during storage to maintain battery health
- Avoid full-throttle starts from cold; allow system to stabilize before heavy use
- Inspect wiring, connectors, and display mounts periodically for looseness
- Use only the official charger and avoid overheating during charging sessions
- Update settings/firmware (if available) for optimal performance and safety
