A panoramic portrait of the wonderous vehicle whose passenger is also its engine.

A toy, a tool, a liberator, or complete nuisance: the bicycle has been many things to many people over the decades, yet it endures as the most popular form of transport in the world. How has such a simple machine achieved so much?

Combining history, travelogue and memoir, Jody Rosen reshapes our understanding of this ubiquitous vehicle from its invention in 1817 to its present-day renaissance as a 'green machine'. Readers meet unforgettable characters: women's suffragists who steered bikes to the barricades in the 1890s, a Bhutanese king who races mountain bikes in the Himalayas, astronauts who ride a floating bicycle in zero gravity.

By examining the bicycle's past and peering into its future, Two Wheels Good forms a joyful ode to an engineering marvel of global importance.
