We all know that he bought a new bike but won’t protect himself, so he won’t last long.Today we are going to discuss how to maintain the bike. In the maintenance of a bicycle, the most important and basic item is very important to check the condition of the bicycle before riding, and it is often forgotten, so before riding, remember to do the following inspection:

Check riding posture: If you’re not riding your own car, set the seat cushion to the right height before riding.

Check the tightness of the screws in all parts: check whether the quick removal of the front and rear wheels and seat cushion poles are locked, check whether the handlebars are fixed, and whether the other screws are loose.

Check the tire: check whether the tire pressure is enough, if it is insufficient, hit the appropriate pressure, check whether there are cracks in the tire wall, whether the cut lines are too shallow. If necessary, replace the outer tire.

Check the brake: try to pull the front and rear brake, check whether the brake can really be stopped.

Check the front wrist: brake the front brake, shake the body before and after, if there is a shaking gap, means that the front wrist must be adjusted.

Check the transmission: after starting, try to change the front and rear speed respectively, whether it can be smoothly changed to each gear, whether there will be a strange sound.
