Bike Cult: The Ultimate Guide to Human-Powered Vehicles by David Perry
Family of Cycling Machines
This family of cycling machines includes anything human-powered, with any number of wheels, hulls, or wings, that provides go power for mobility or ergo power for work.
There are roughly 15 general categories of cycling machines and about 100 specific types. Most cycling machines have been mass-produced, many are built in limited numbers, some are one-of-a-kind prototypes.
Cycling machines are categorized in many ways: by their intended uses, by the numbers of wheels and riders, by the kinds of cycling positions, and the kinds of drive mechanisms. Many bikes and cycles overlap categories, as one type may be used or remade for other purposes. For example, mountain bikes are used as urban roadsters.
Here the word bike describes a two-wheeler and cycle describes all other vehicles and tools with any number of wheels and human-powered mechanisms.
