James Starley, a Frenchman created the first bicycle that uses a very large front wheel, which is known by the name of Penny-Farthing. Penny-Farthing is actually a further development of the Bone-Shaker. Large front wheel that makes the rider to walk longer distances to each rotation, and also a great risk if a sudden stop or glide on derivatives, because the fall would be more pain.

Bicycles are very popular in the 1880s, and is the first bike that gets called Bicycle (two wheels). After all, who bears the name of Mr Bike High (High Bicycle / High Wheeler) precisely one other French named Eugene Meyer,...
