Use and maintenance

Normal riding does not require any skills, but it is the most important and basic item in the maintenance of bicycles. Before riding, it is very important to check the condition of the bicycle, but it is also often forgotten. Therefore, before riding, remember to do the following checks.

Check the riding position size: If you are riding a bike that is not your own, remember to adjust the seat cushion to the appropriate height before riding. Check the tightness of the screws in various parts: Check whether the quick release of the front and rear wheels and seat rod are locked, check whether the handlebar is fixed, and whether other screws are loose.

Check the tires: Check whether the tire pressure is sufficient. If it is insufficient, increase it to the appropriate pressure. Check whether there are cracks in the sidewall and whether the cut tread is too shallow. If necessary, replace the tire. Check the brakes: Test the front and rear brakes to check whether the brakes can actually stop.

Check the front wrist: Apply the front brake and rock the body back and forth. If you feel a shaking gap, it means the front wrist needs to be readjusted. Check the transmission: After starting, try changing the front gear and the rear gear respectively. Whether you can change to each gear smoothly, and whether there are any strange noises.
