        Bicycles are tools for people to walk, the easier and more flexible they should be ridden, so the area where the bicycle bearings rotate is generally equipped with steel balls, which is the ball bearings mentioned below. The role of steel balls is to reduce friction, protect parts, improve the efficiency of use, as we all know, at the same pressure, rolling friction is much less than sliding friction, if lubricating oil is often added to it, the oil film will make the contact surface separate, we use bicycles will also be more labor-saving.

1. Wheel front hub and rear hub.

2. Chassis of the car, which has an axle that connects two foot pedal cranks together.

3. Handlebar fork tube, used to make the handlebar able to turn.

4. Flywheel, the bearing here has a double function, in addition to reducing friction, can also help achieve a one-way function.

The transmission part of the bicycle is a chain mechanism, and its transmission device includes: active gear (wheel), passive gear (flywheel), chain and transmission. Gear ratio and transmission ratio is related to the efficiency of the use of the bicycle, in general, the number of teeth of the wheel gear is more than the number of teeth of the flywheel, that is to say, every time a person pedals a week, the number of passive gear turns will be more than one week.

The flywheel is the passive gear at the rear end of the bicycle chain, which has an internal thread inside in order to fix it at the right end of the rear axle, maintain the same plane with the sprocket, and connect with the sprocket through the chain to form the drive system of the bicycle.
