You can choose to ride using the motor only, or with pedals only or with both together.

Electric Bicycles have electric motors, usually inside the hub of either the front or rear wheel.

Folding bicycles can easily be stored in a small place or carried a long distance on an airplane or other public transport.

There are bicycles for three and more people.

The tandem bicycle is made for two people.

Some utility bicycles are similar, for riders who make frequent stops. The manufacturers of bicycles changed the location of the top tube to make it easier for women to sit down on them while wearing a skirt. When women began to ride bikes, they wore long skirts.

The difference between a woman's bicycle and other bicycles is the location of the top tube.

The front wheel is connected to the handlebar, so turning the handlebar from side to side swivels the front wheel which steers the bike. The cyclist's feet push the pedals to make them go around in circles, which moves the chain, which turns the back wheel of the bike to make the bike move forwards. During this time the bicycle became very popular.īasic components common to most bikes include a seat, pedals, gearing, handlebar, wheels, and brakes, all mounted on a frame. Later inventions included better brakes, and gears which made cycling over hills much easier. As a result, better hand brakes were invented, and a different type of brake which could stop the bike if the pedals were turned backwards. However, this meant the rider could no longer stop the bike by backpedaling.

This was a device inside the hub of the back wheel that allowed the wheel to spin even if the rider wasn't pedaling. This made safety bicycles more comfortable. In 1888, Scottish inventor John Boyd Dunlop re-invented a type of tire which was filled with air. Brakes operated by hand levers on some bikes also increased safety. Instead of pedaling and steering with the front wheel, the safety bicycle steers with the front wheel while the pedals turn the back wheel using a chain. When stopping, the rider can simply put down a foot instead of completely dismounting. It was called the safety bicycle because it much easier to ride than the penny-farthing. This had two wheels the same size so that the rider could sit at a lower height. In 1885, the safety bicycle was invented. Several improvements were made in the 1880s and '90s.

However, it was difficult to ride, since it could fall easily and the rider would fall far. This design was called the penny-farthing bicycle. Later inventors made bikes out of metal only, and made the front wheel very big, giving higher speed.

However, it took a lot of effort to turn the pedals. In the 1860s, French inventors added pedals to the front wheel. However, it did not have pedals, so the rider would have to push their feet on the ground to make it move. The front wheel could be turned using the handlebars in order to steer the bike. In 1817 a German professor, Baron Karl von Drais, created the first two-wheeled bicycle. Wooden Draisine (around 1820), the first two-wheeler
