XIII. Awareness on a Ride
1. Co-riding is prohibited! According to traffic regulations, riding with
any passengers is highly restricted.
2. At places where the visibility is poor, turn on the lights for safety
concerns.
3. On snowy, icy, muddy or bumping places, or wet iron plates, where
the vehicle tends to slide over, please stop riding.
4. Ride properly and respect other vehicles and safety concerns. Do not
perform snake-riding, single-hand riding, bouncing and so on.
5. Do not ride under conditions of alcohol, medication or illness. These
cause human body to react slowly and cause danger.
6. Do not perform single-hand riding. Unless necessary, please keep
both hands on the grip properly. Wear a rain coat on rainy days.
7. Be aware of safety when carrying goods.
8. During a ride, never wear clothing that might cause danger, such as a
dress that may get caught by the wheel or gear.
9. Do not get your limbs or objects too close to a rolling spot, such as
the wheel, chain, gear, etc., to avoid any cause of danger.
10. Wading depth: The bike is an electronic product. Avoid using the
vehicle on a place where wading depth reaches 10 cm, to avoid water
damage on motor or electronic system.
11. When moving the bike, please turn o󽗈 the power in case the motor is
activated and causes unintentional acceleration.
12. Whenever a sharp brake occurs, simultaneously perform both brakes

front brake at the 󽗉rst place. Left brake lever controls the front brake
and right brake lever controls the rear brake.
13. Highly recommend to wear a lately-certi󽗉ed helmet that is suitable
