Hint:A bicycle which is also known as a cycle or bike is a single-track, human- or motor-powered vehicle with two wheels mounted to a frame, one behind the other. A cyclist, also known as a bicyclist, is a person who rides a bicycle.

Complete answer:
The amount of air pumped into a relatively fixed space determines how hard a tyre becomes when filled with air. The more you put in, the higher the pressure and the tougher the tyre becomes until the tyre explodes or pops off the rim if you put in enough.

The amount of air you put in the tyre for proper inflation is influenced by the size or diameter of the tyre, the weight of the rider and vehicle, and the rim width. As air is pumped into a bicycle tube, the air pressure exerted by gas molecules colliding with the inner walls of the tube causes the rubber tube to inflate. The tyres feel hard because of the air pressure.

Additional Information:
A brick resting on a surface, for example, exerts a force on the object it is resting on equal to its weight. We now know that a rectangular brick has a thick front surface and a thin back surface. We can effectively change the pressure acting on a surface by altering the direction of the brick sitting on the surface. In other words, as the surface area gets smaller, the pressure increases.

Note:Remember that the force applied perpendicular to an object's surface per unit area over which that force is spread is known as pressure. Pressure is measured in a variety of ways.Since the pressure is proportional to the area over which the force acts, the pressure may be changed without changing the force. When the force applied remains constant, the pressure increases as the surface becomes thinner and vice versa.
