If we buy a bicycle with a suitable frame size, what should we do first before using the bicycle? That is, you need to adjust some bicycle parameters so that you can use the bicycle in a correct and comfortable riding posture. The riding posture is wrong. Firstly, you can’t exert effort when riding by yourself, and you are prone to fatigue. Secondly, you may damage your knees and affect your health.
So, the first step we need to do is to adjust the height of the car seat to suit our height and leg length. Pull off the quick release of the seat tube or the locking bolt, stand by the car, stand upright, pull up the seat tube until the upper edge of the seat reaches our hips, and then check whether the seat tube has a safety line exposed, if it is exposed For safety, then this frame is too small for you and needs to be replaced. Then lock the seat tube, find a chair or a wall, sit on the bicycle, hold the wall with your hands or hold the chair with your feet, sit on the bicycle steadily, with the forefoot against the pedals, and rotate to the lowest end , At this time, it’s correct to close, our knees are slightly bent, if not, we have to re-adjust.
