Maintenance Tips
- Keep bike dry; IPX5 is splash-resistant only—avoid deep water, rain storage, and pressure washing
- Wipe frame, suspension, wheels, and drivetrain after every ride to remove dirt and mud buildup
- Regularly check and tighten bolts (especially swingarm, shock mounts, and axle nuts) due to high torque vibration
- Inspect hydraulic brakes often; top up/bleed if braking feels soft or inconsistent
- Check tires (19” front / 17” rear) for wear, cuts, and proper pressure for grip and safety
- Inspect suspension for leaks, squeaks, or loose bushings; lubricate pivot points lightly
- Keep battery (72V 30Ah) between ~20–80% for daily use; store at ~50–60% for long periods
- Recharge at least once per month during storage to maintain lithium cell health
- Avoid full-throttle stress when cold; let motor and battery warm up before hard riding
- Monitor motor temperature after long rides—overheating can reduce lifespan
- Keep chain/single-speed drivetrain clean and properly tensioned (if applicable)
- Update/display check and wiring inspection periodically to prevent vibration-related faults
- Use only the official charger; avoid overheating during fast charging cycles
