Brakes are an essential part of a bike. The two most common types are disc brakes and V-brakes. Disc brakes are more effective, but need to be maintained more often, while V-brakes are easy to maintain and last longer. Other braking systems include drum brakes or a coaster brake (in children's bikes).
Serves to attach the front wheel and brake.

Tires serve to protect the tube inside and they optimize the riding attributes of your bike, both on the road and in terrain. Mountain bike tires are wide and have a complex pattern that allows for movement on difficult terrain. Road bike tires, on the other hand, have a shallow pattern and are thin and smooth.
Tires serve as a protection of the inner tube and optimalize the riding qualities of a bike in terrain and on the road. Mountain bike tires are wide and have complex patterns, allowing for riding through hard terrain. Road bikes on the other hand have thin and smooth tires with only a shallow pattern.
Levers or grip shifters change the revolving ratio in the relation of the front sprocket wheel (crankset) and the rear sprocket wheel (cassette) with the help of the front and rear derailleur.
We come across lever shifts most often, since they usually also feature a precise indicator. Children’s and junior bikes often feature user-friendly grip shifts that don’t need a lot of strength. They are basically a part of the handlebar grips. Different levers are used on road bikes with bullhorn handlebars where they are part of the brake levers and the rider shifts gears by pushing the lever sideways.
Gear shifting on the chainring.
Gear shifting on the rear wheel.
On modern bikes, sprocket wheels on the rear wheel are affixed to a cassette. Along with the front derailleur, they add more gears and the rider can choose the optimal speed/pedalling ratio. Cassettes can be taken apart and the sprocket wheels exchanged for others (new or with different number of sprockets).
Metal part connecting the pedal to the centre.
