700c Fixed Gear Bike  manufacturer introduces the precautions for riding a bicycle:

1. If the seat is too hard, foam plastic can be used to make a soft seat cover on the seat to reduce the pressure on the lower part of the seat.

2. Adjust the height and angle of the seat. If the seat is too high, the buttocks will inevitably move left and right when riding, which will easily cause abrasions on the part. So you need to ride carefully.

3. When riding for a long time, pay attention to changing the riding posture to make the center of gravity of the body move.

4. When riding a variable speed bike for the first time, the speed should not be too fast and the time should not be too long. Accelerate and overtime after the body adapts.
