The core maintenance principles
CEMOTO's owner manual sets out a small number of maintenance rules that cover most of what matters:
1. Battery and charger Use only the included battery and the included battery charger. If either is discontinued or out of service, replace it immediately with the recommended part supplied for your model. Using a non-certified charger voids the battery warranty and creates a fire risk.
2. Wheels and drive system Wheels and drive system components wear normally with use. It is the rider's responsibility to systematically check the wheels for excessive wear and to properly adjust and replace drive system components as needed.
3. Spare parts Most common spare parts are available through CEMOTO distributors and the accessories range.
4. Electrical components are not user-serviceable The electrical elements can only be cleaned on the outside. There is no need to maintain the inside, and you should not open them yourself. Opening sealed electrical components voids the warranty on those parts.
5. Do not overload Overloading damages the electrical components — plastic parts can deform from high temperature, or the fuse socket can be damaged by heat. Overload damage is not covered by warranty.
6. Cut the power when not in use For safety, cut the power supply when the bike is not being used. Turn the power switch off when the motorcycle is not in use.
7. Clean only the exterior Never pressure-wash bearings, seals, connectors or the motor. See Cleaning & Storage.
Fastener check reminder
Fasteners settle after assembly and during the first rides. After your first 20–30 minutes of riding, re-check:
- Front and rear axle nuts
- Handlebar stem clamp bolts
- Brake caliper mounting bolts
- Pedals
- Motor mounting bolts
- Suspension mounting bolts
Use the values in Torque & Fastener Reference.
The chain tension rule
Chain slack should be approximately 15 mm. Check it frequently — chain tension affects drivetrain noise, wear rate and the risk of derailment. Adjustment procedure: loosen the rear axle nuts, adjust the tension screw, then retighten the axle nuts.
See Drive & Transmission.
Tire pressure rule
Check air pressure frequently. If the pressure is too low, rolling resistance increases and the riding range is reduced. Under-inflation also risks damaging the rim and pinching the inner tube.
Use a hand pump with an integrated pressure gauge and a Schrader-type valve. Do not use a pressurized gas-station air system — those are designed for car tires at much higher pressure and volume.
Serviceability by design
CEMOTO selects serviceable components deliberately: the range is built around standard, replaceable parts rather than proprietary assemblies, and compatible D-series parts and accessories are available through the CEMOTO accessories range. This means:
- Wear items (pads, tires, chains, cables) can be replaced rather than requiring a whole assembly.
- The controller is programmable and the display parameters are accessible.
- A local bike shop can carry out most maintenance work.
Local bike shops can generally service most components, since most are standard. For warranty-related repairs, contact CEMOTO first to ensure coverage is preserved.
