Knowing the Parts of  a Bicycle

A vehicle with a simple machine and involves a lot of mechanization is a bicycle. It is made up of many bicycle parts put together. The efficient working of the bicycle because of perfect synchronization in the functioning of all bicycle parts. A modern bicycle has many new elements, the same main bicycle parts belongs to the standard bicycle. The basic bicycle parts comprise; the frame: Many tubes welded together is made for a bicycle frame. The front wheel is movable and it is hold by the front fork.
The wheels: wheels including bicycle parts like a hub, rubber tires, metal rim and the spokes. The brakes: they include the actuators on the handlebar, calipers, brake pads and brake cable. The chain and gears: they consist of the front chain wheels, the rear freewheel, the shift levers on the handlebars and the cables. Other bicycle parts include the seat, seat posts, handlebars include the stem, bicycle lights, cranks, and pedals.
Gears and ball bearings
Most racing bicycles have bicycle parts like gears. Gears basically serve the purpose of reducing the size and diameter of the wheel. These bicycle parts adjust the direction of rotation. Multiple gears on a bicycle helps change the distance the bicycle moves forward with each stroke of the pedal. A mountain bike has 24 gears. Chain wheels are the gears at the front. Most bikes have 2-3 chain wheels. The freewheel, at the rear, has 5-9 gears on it. It spins freely in one direction and locks in the other. This enables the bike to coast, when not pedaling. There are front and rear derailleurs to change the gears.
Ball bearings are bicycle parts in a bicycle serve to reduce friction. These bicycle parts are found in the front and rear hubs for the wheels, the pedals, the fork tube, the bottom bracket and in the freewheel. These bicycle parts need to be periodically cleaned and greased. Expensive bicycles have sealed bearing cartridges that don’t need lubrication.
Materials used
Bicycles including bicycle parts need to be strong and lightweight. Alloy steel is used for making the frames and fork tubes. The handlebars, seat posts and brake levers are made of aluminum alloy. Aluminum alloy frames are affordable. Carbon frames, titanium and advanced steel alloys frames are also available.
