Hybrid bicycle

Hybrids typically borrow the flat, straight handlebars and upright seating posture of a mountain bike, which many bicyclists find comfortable and intuitive.

[2] From the early 20th century until after World War II, the utility roadster constituted most adult bicycles sold in the United Kingdom and in many parts of the British Empire.

In Britain, the roadster declined noticeably in popularity during the early 1970s, as a boom in recreational cycling caused manufacturers to concentrate on lightweight 10–14 kg (23–30 lb), affordable derailleur sport bikes, actually slightly-modified versions of the racing bicycle of the era.

[citation needed] A trekking bike is a hybrid with all the accessories necessary for bicycle touring – mudguards, pannier rack, lights etc.

It typically features derailleur gearing, 700c wheels with fairly light 29 mm (1+1⁄8 in) tires, a carrier rack, full fenders, and a frame with suitable mounting points for attachment of various load-carrying baskets or panniers.

A well-equipped commuter bike typically features front and rear lights for use in the early morning or late evening hours encountered at the start or end of a business day.

[2][5][6][7] It usually features mountain bike-sized 26-inch (ISO 559) wheels, a more upright seating position, and "middleweight" 38–50 mm (1.5–1.95 in) heavy belted tires designed to withstand road hazards commonly found in the city, such as broken glass.
