ŸDon't carry packages or passengers that will interfere with your visibility or control of the scooter. Don't use items
that may restrict your hearing.
ŸMaintain a comfortable stopping distance from all other riders, vehicles and objects. Safe braking distance and
forces are subject to the prevailing weather conditions.
Wet Weather
In wet weather you need to take extra care.
Brake earlier, you will take a longer distance to stop.
Decrease your riding speed, avoid sudden braking, and take corners with additional caution.
Be more visible on the road.
Wear reflective clothing and use safety lights.
Potholes and slippery surfaces such as line markings and train tracks all become more hazardous when wet.

The product is not allowed to use by handicapped people!
Check Before Driving
Please do a check before driving in order to ensure your safety of driving.
ŸOpen power lock, check whether all indication of scooter head is normal, brake power cut is effective?
ŸWhether tyre pressure is normal?(Short inflation will influence running speed or continual mileage.)
ŸWhether nut of front and rear wheel is locked
ŸWhere electric energy is enough?
ŸWhether braking system is adjusted suitably and reliably?
ŸWhether handgrip and saddle is adjusted well and tightened?
