Maintenance Tips
- Keep bike dry; avoid rain, puddles, and pressure washing to protect motor and electronics
- Clean frame, suspension, chain, and drivetrain after every ride to remove mud, dust, and sand
- Regularly tighten bolts (swingarm, axle, motor mount, frame hardware) due to high vibration/torque
- Inspect hydraulic brakes often; bleed or adjust if braking feels soft, noisy, or uneven
- Check tires for wear, punctures, and correct pressure for traction and stability
- Maintain chain and sprockets: clean, lubricate, and adjust tension frequently
- Inspect suspension for oil leaks, stiffness, or loose bushings; service when needed
- Avoid full-throttle starts when cold; let motor and battery stabilize before heavy riding
- Battery care: keep ~20–80% for daily use; store at ~50–60% for long-term health
- Recharge at least once per month during storage to preserve lithium cells
- Monitor motor temperature after long climbs or aggressive riding to avoid overheating
- Inspect wiring and connectors regularly due to vibration stress in off-road use
- Use only the official charger; avoid overheating during charging cycles
- Keep display/firmware (if applicable) updated for better performance and safety control
