The first step is to fix the handlebar of the mountain bike, and then unscrew the fastening screw behind the stem. Use a 5mm hex key to remove the stem top cover. Remove the stem and add spacers according to the height you want to adjust. Put the stem back on and place the spacers you just took out on top. Then put the top cover on. Tighten the screws on the top cover so that the self-driving handlebars are raised. After riding the bicycle for a certain period of time, each component should be checked and adjusted to prevent the parts from loosening and falling off. A small amount of engine oil should be regularly injected into the sliding position to ensure its lubrication.
When setting the height of the cushion, raising the cushion is the most taboo. On the road, there are many middle school students who like to be handsome, deliberately raise the cushions, and pretend to have long legs. This saddle height is dangerous because the knees straighten up when you step on it. Like cycling, keeping your knees straight when you need to step on your feet frequently will not only cause a "boom" that will affect the continuity of your pedaling but also damage the ligaments of your knee joints and feet. If you raise the cushion, you will have the illusion that the pedaling force is "straight out", so you can step in this position, otherwise the muscles and knee joints will be worn out and easily injured. So remember! Don't forget to keep your knees straight when pedaling on a bicycle.
The height of the seat will affect the force on the knees. Before riding, please adjust the height of the seat to "when the pedal reaches the lowest point, the extension line of the thigh and the vertical line of the ground form an angle of 25-30 degrees, that is, the knee Slightly bent", too high or too low a seat will cause knee discomfort during riding, a reasonable seat height can increase the comfort when riding, and at the same time reduce the knee when the seat. height is too high or too low Stretch and compressive strength.
