A folding bicycle is a bicycle designed to fold into a compact form, facilitating transport and storage. When folded, the bikes can be more easily carried into buildings and workplaces or onto public transportation (facilitating mixed-mode commuting) or more easily stored in compact living quarters or aboard a car, boat or plane. Folding mechanisms vary, with each offering a distinct combination of folding speed, folding ease, compactness, ride, weight, durability and price.

Distinguished by the complexities of their folding mechanism, more demanding structural requirements, greater number of parts, and more specialized market appeal, folding bikes may be more expensive than comparable non-folding models.

 Folding methods

Folding mechanisms are highly variable.

Half or mid fold Many folding frames follow classic frame pattern of the safety bicycle's diamond frame, but feature a hinge point (with single or double hinges) allowing the bicycle to fold approximately in half. Quick-connect clamps enable raising or lowering steering and seat columns. A similar swing hinge may be combined with a folding steering column. Fold designs may use larger wheels, even the same size as in non-folders, for users prioritizing ride over fold compactness.

Usage and Portability:

Folding bicycles are particularly suitable for urban commuters. Mixed-mode commuters who deploy the fold mechanism several times daily for portage aboard public transport may prioritize a bike with an easy, quick fold. Marine users, seeking a bike for incidental shore mobility, may prioritize the compactness of the folded bike. Riders using their bikes less frequently may prioritize speed and comfort of ride over ease and quickness of folding. People who live in a small apartment often prefer a folder as it can be more conveniently stored indoors than a full-sized bicycle.

As folded bikes require less space, they are allowed by some public transportation systems, e.g., Transport for London, which allows folding bikes to be carried at any time on buses and Underground lines. Other public transportation systems may ban or restrict other bicycles, or may require that folding bicycles be enclosed in bags or covers to protect other passengers. Some may restrict folding bikes to off rush-hour periods. Covers range from custom made bags, to bin-liners and shopping bags for smaller folders. Airline baggage regulations may permit folding bikes as ordinary luggage, without extra cost.
