Maintenance Instructions
Maintenance and Repair
For your driving safety and to keep your vehicle in excellent condition, please have it regularly serviced and cleaned.
Regular Maintenance and Self-Inspection Checklist
Check that the front and rear wheel bolts are securely tightened. Inspect the tire treads for wear or cracks. Ensure the gear‑shifting system operates smoothly. Verify that the front and rear tires are properly inflated. Confirm that the bell and rear reflector are in good working order. Examine all joints to ensure they are tightly fastened and free from corrosion; make sure the brake cables are lubricated and functioning correctly. If the bike will remain unused for an extended period, be sure to charge it regularly—typically about once a month—to help prolong your battery’s lifespan.
Maintenance and Cleaning Instructions
Do not use high-pressure water jets, as this may cause moisture to penetrate internal electronic components and wiring, posing a potential safety hazard. For painted or plastic surfaces, gently wipe away dirt with a cloth dampened with a neutral detergent, then dry the area with a clean, dry cloth. To maintain metal parts of the vehicle, apply a suitable lubricant; however, do not lubricate the front or rear brakes, wheel rims, or tires.
