• The battery will faster lose capacity in low temperature conditions. To be more specific, the usable capacity is 70% at -10°C, 85% at 0°C and 100% at 25°C.

• The best battery capacity performance for storage is 50%.
  Storing battery with less than 10% or more than 90% over along period of time will cause irreversible capacity loss to the battery.

• The battery needs to take out from the scooter for storage longer than one week. In this condition, please keep the battery at the temperature of 0°C to 20°C with capacity of 30%-70%. It’s advised to have at least one cycle of charge and discharge every 2 months to minimize battery capacity loss during storage.

• Falling may cause uncontrollable internal damage to the battery and may cause leakage, overheat, smoking, fire or explosion.

DOs and DON Ts while Riding

Before Riding
Please check the following details before riding .

1. Steadiness
2. Steering flexibility
3. No axial displacement or loosening

Braking| Braking lever has 5 to 9mm idle travel.
Tyres|

1. The air pressure range of the front tyre is 29 to 36psi; the air pressure range of the rear tyre is 33 to 36psi.
2. Proper tyre tread depth
3. No cracks or openings
4. Minimum load-capacity index: front 23, rear 49.
5. Minimum-speed category: B.

Battery| Adequate for planned distance to travel.
Lights| Check all the lights-High Beam, Low Beam, Brake Light, Turn Signal Indicator, etc.
Horn| Check whether the horn can work.

Braking Precautions

Adjust the scooter upright before applying brakes. If the tyres are locked and the scooter loses steering ability resulting from excessive braking force, loosen the grip on the braking lever and the tyres will be working again and the scooter will be stabilized. Try to maintain a 1 :1 ratio of front and rear braking force on slippery roads.

Caution: For your safety, do not exceed the speed limit, use the brakes gently to maintain at safe speed while riding downhill.
ATTENTION: Inexperienced riders tend to use the rear brake only, which will accelerate the wear of the brake and result in a longer braking distance.
Warning: Using the front brake or rear brake only is dangerous because of possible grip or control loss. Pay extra attention and use the brakes gently when riding on damp, slippery roads, and around corners. Otherwise, riders will be exposed to great danger.
