An explanation about 'How a bike works'


The bike is a mechanical machine which is an easy type of transport
that can move people and goods around from place to place.  A bike is made up of many different parts such as: pedals, wheels and axles which makes it move effectively and function properly.  Firstly, you put your helmet on and hop on your bike.  Secondly, you keep your balance and start pedalling to get you going. Thirdly, when you are going a bit faster, change your gears and just keep on pedalling to get you going.  The bike can keep going until you stop or you use the brakes to stop. The brakes squeeze on the wheel to make it stop.
Now you know what is on your bicycle, how to ride it and a new word... ‘FRICTION.’
