Serves to attach the front wheel and brake.
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 harder to maintain. On the other hand, V-brakes' maintenance is easier and they will last longer. ther braking systes include drum brakes or a coaster brake (children's bikes).

Hubs are placed in the centre of the wheels. A hub is made up of bearings, cups and nuts and is attached to the bottom bracket that connects the wheel with the fork.
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.
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).
A metal circle with a U-shaped profile. It creates space for the inner tube and tire. Bikes designed for professional use and therefore more demanding riding style have double-walled rims. Such rims provide higher durability and better safety. Rims for regular bikes are usually made of dural, rims for special bikes can be made of special alloys or composites.
