A type of two-wheeled bicycle in which the front wheel is much larger than the rear wheel. Building such a large wheel was only possible in 1869 after the patent by James Starley and William Hunter of Great Britain for a wheel with wire spokes that worked in tension. Prior to the invention of the chain transmission, the pedals on the bicycle were attached directly to the front wheel. In order to obtain higher speed, it was enlarged up to 2 meters in diameter. Unfortunately, it had a limitation in the form of the length of the driver’s legs, who had to reach the pedals. Riding the bicycle was not safe because of the height – the rider on the saddle did not reach the ground with his feet.
