PLEASE HELP ME WITH MY IELTS ESSAY TASK 1

The illustration shows a two wheeled bicycle which is a relatively recent invention.

Describe to someone with no prior knowledge how a bicycle operates.

MY ESSAY:

The illustration depicts the components of a bicycle, a small, human powered land vehicle.

Overall, it has five main parts: a frame, saddle, metal chain, wheels and pedals. All of the components are fitted to the frame.

The frame is made of several metal tubes. The tubes are linked together and form a main triangle, a paired rear triangle and a reverse L-like structure front part that is steerable. The seat and pedals are positioned at the top and the bottom of the tube that is part of the rear and main triangle, respectively. The head of the L part is linked to the handlebars, which suspends four different components: a gear lever, brake lever and a speedometer; cables connect these four to the two wheels and a set of brakes, which allow them to control the speed and movement of the bicycle. The two wheels have a tire that is connected to a wheel hub by a series of metal spokes. The pedals are screwed onto a notched cog. A metal chain connects the cog and the wheel hub, allowing the pedaling of the bike.
