Elegant electric city bike

How to use an adult electrical city bike safely? Do not occupy safe passages when parking electric bike, and the parking area should be equipped with sufficient fire-fighting facilities and equipment; never pull wires privately, and park and charge at regular electric vehicle charging places. Ride safely, obey traffic laws, and build a civilized city together.A safety helmet must be worn when riding an adult electrical city bike on the road, and the electric bike helmet must take into account both safety and balance. The closer the helmet's center of gravity is to the head, the higher the comfort, and the soft foam spacer inside the helmet protects when the helmet is hit hard. In addition, reflective signs can be posted on the helmet, so that when riding at night, it can also remind surrounding vehicles to pay attention to avoidance.
