Background
The bicycle support is an essential part of two-wheel vehicles such as electric bicycles, motorcycles and the like, and plays a role in supporting and fixing the bicycle body when the bicycle is parked. The existing vehicle support is divided into a single support and a double support, wherein the single support is arranged on one side of the vehicle body, and the vehicle body is in an inclined state when the vehicle is parked, so that the single support mode is not stable enough; the double support is that the two sides of the car body are provided with the car supports, so that the two sides of the car body can be supported when the car is parked, and the double support mode is more stable than the single support mode. However, the existing double bracing has the following disadvantages: the two supports are of an integrated structure, the widths of the two supports are the same in the supporting state and the lifting state, so that the width between the two supports is increased to increase the supporting stability of the two supports to the vehicle body, and after the two supports are lifted, the occupied space is increased due to the large width between the two supports, and hidden danger is caused for riding safety.
