Anotations

Scope note:

Two- or three-wheeled, simply constructed light vehicles propelled by the rider by pedals, treadles, levers, or with the feet directly on the ground, while seated astride a central bar; may or may not be steerable and the front wheel is often larger than the rear one(s); usually restricted to those vehicles built from the 1790s to around 1870. For similar lightweight vehicles provided with comfort- or speed-enhancing features and built after about 1870, prefer "bicycles" for those with two wheels in tandem or "tricycles" for three-wheeled versions.
