1886 Swift Safety Bicycle. Vehicles that have two wheels and require balancing by the rider date back to the early 19th century. The first means of transport making use of two wheels arranged consecutively, and thus the archetype of the bicycle, was the German draisine dating back to 1817.
Usually this is assumed to be independent of (speed of the bicycle on the road) although it is recognized that it increases with speed. Measurements on a roller-mechanism give low-speed coefficients of 0.003 to 0.006 for a variety of tires inflated to their maximum recommended pressures, increasing about 50% at 10 m/s. [21]
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of ...

It was almost 40 years until "velocipede" came into common usage as a generic term, with the launch of the first pedal-equipped bicycle, developed by Pierre Michaux, Pierre Lallement and the Olivier brothers in the 1860s. The Michaux company was the first to mass-produce the velocipede, from 1857 to 1871. That French design was sometimes called ...
In the early 1860s the first true bicycle was created in Paris, France, by attaching rotary cranks and pedals to the front wheel hub of a dandy-horse. The Olivier brothers recognized the commercial potential of this invention, and set up a partnership with blacksmith and bicycle maker Pierre Michaux, using Michaux's name, already famous among enthusiasts of the new sport, for the company.
