Variable accommodating resistance training machines

It is regarded as the modern bicycle's forerunner; Drais introduced it to the public in Mannheim in summer 1817 and in Paris in 1818.

This, in turn, required gearing—effected in a variety of ways—to efficiently use pedal power. Starley's 1885 Rover, manufactured in Coventry Further innovations increased comfort and ushered in a second bicycle craze, the 1890s Golden Age of Bicycles.Having to both pedal and steer via the front wheel remained a problem. In 1888, Scotsman John Boyd Dunlop introduced the first practical pneumatic tire, which soon became universal.By the turn of the century, cycling clubs flourished on both sides of the Atlantic, and touring and racing became widely popular.The Raleigh Bicycle Company was founded in Nottingham, England in 1888.The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885.

But many details have been improved, especially since the advent of modern materials and computer-aided design.

His uncle, Josiah Turner, and business partner James Starley, used this as a basis for the 'Coventry Model' in what became Britain's first cycle factory.1886 Rover safety bicycle at the British Motor Museum.

The first modern bicycle, it featured a rear-wheel-drive, chain-driven cycle with two similar-sized wheels.

In the early 1860s, Frenchmen Pierre Michaux and Pierre Lallement took bicycle design in a new direction by adding a mechanical crank drive with pedals on an enlarged front wheel (the velocipede). Another French inventor named Douglas Grasso had a failed prototype of Pierre Lallement's bicycle several years earlier.

Several inventions followed using rear-wheel drive, the best known being the rod-driven velocipede by Scotsman Thomas Mc Call in 1869.

These bicycles were difficult to ride due to their high seat and poor weight distribution.
