Maintenance Tips
-
Battery health (72V system): Avoid full drain; keep charge between ~20–90% for longer lifespan. Don’t leave on charger overnight regularly.
-
Heat management: After hard riding, let battery and motor cool before recharging to prevent thermal stress.
-
Tire optimization: Run slightly lower PSI for dirt traction, higher PSI for road use—check before every ride.
-
Brake tuning: Bleed hydraulic brakes periodically; replace pads early to avoid rotor damage on high-speed descents.
-
Bolt check routine: Inspect axle nuts, suspension bolts, and stem every 1–2 rides (high torque = vibration loosening).
-
Chainless motor care: Keep hub motor vents clean; avoid mud buildup and do not pressure-wash the motor area.
-
Suspension setup: Adjust preload based on rider weight + terrain; softer for trails, firmer for jumps/high speed.
-
Controller protection: Avoid water ingress; check connectors for corrosion, especially after wet rides.
-
Charging safety: Use only original 72V charger; plug into stable power source (voltage spikes can damage BMS).
-
Storage tip: Store at ~50–70% battery if unused for weeks; recharge monthly.
-
Riding habit tip: Avoid full-throttle starts repeatedly—reduces controller and battery stress.
-
Post-ride routine: Clean frame, inspect spokes, check tire cuts, and listen for unusual motor noise early.
