Precautions for purchasing bicycles:
1. When choosing a bicycle for sports, the first thing to pay attention to is whether the size of the frame is suitable for the rider’s figure. The measurement of frame size generally takes the length of the frame riser as the standard, and the longer the riser is, the longer the frame body length is.
2. The frame is the soul of a bicycle. A good bicycle frame must meet the three conditions: lightweight, sufficient strength, and high rigidity. As a good quality bicycle, the lighter the weight, the better. In this way, the less effort and the faster you ride. Enough strength means that the frame will not have the safety concern of breaking and bending under high-intensity riding. High rigidity means that the frame should be hard enough.
