Finally a metallic contraption was introduced. The pedals were still attached directly to the front wheel with no freewheeling mechanism. Solid rubber tires and the long spokes of the large front wheel provided a much smoother ride. The front wheels became larger and larger as makers discovered that the larger the wheel, the farther you could travel with one rotation of the pedals. You would purchase a wheel as large as your leg length would allow. This machine was the first one to be called a bicycle. These bicycles enjoyed a great popularity among young men. One problem was that the centre of balance was very high and had most of its mass in the front so one small bump and the rider fell straight down on his face!

The next step in bicycle innovation was the three-wheeler. It had a similar design but was lower and had three wheels. It was used for women mostly, and men with high status. It was advanced because it had rack and pinion steering, the differential, and band brakes.

Soon later, a bicycle with a much smaller front wheel was introduced. It solved the problem of toppling forward. The bicycle was then called "ordinaries" because they were less advanced.

                 Finally a design with two same-sized wheels was innovated. It had the technology of of a metalic sprocket and a chain to power the whole bicycle under a riders feet. This design was much safer than the tall designs, but was less comfortable because the shock of the road was felt immediately.

AT LAST THEY APPLIED PNEUMATIC TIRES TO ABSORB SHOCK AND THE MODERN BICYCLE WAS FOUND
