However, your full compliance with this user manual does not fully exclude the risks caused by non-compliant or improper operation by other people or of other vehicles.Like all other vehicles, the higher the EAPC’s speed, the longer the braking distance. It is essential for you to stay alert and keep a proper speed and distance from other people and vehicles during your ride. Please stay vigilant before you enter unfamiliar terrain and maintain a low speed.
Please respect pedestrians’ right of way while riding. Avoid startling pedestrians, especially children. When you are about to pass a pedestrian from behind them, alert the pedestrian and slow down when you pass them. Try to pass any pedestrians from their left side as much as possible (applicable to countries and regions where vehicles drive on the right). When you come face to face with a pedestrian, stay on the right side of the pedestrian and slow down when you pass. Do not park the bicycle at building foyers, evacuation stairs, and safety exits after use. Please park properly in accordance with the safety rules. One-handed riding is prohibited!
Do not lend the bicycle to someone who does not know how to use it. Before you start riding, check whether the brakes work properly. When you brake, please use the rear brake ﬁrst, and then the front brake. Remember to check the brake tightness. When the brakes are too loose, use an Allen wrench to tighten them. Increase the braking distance when you ride in rain or snow.
Suggested user age: 18 and up.
