What is the term for a bicycle that can be folded for easy storage?

The term for a bicycle that can be folded for easy storage is a folding bicycle.

A folding bicycle is designed to collapse into a smaller, more manageable shape for carrying or storage. Hinges, telescoping seatposts, folding handlebars and other mechanisms can reduce the bike’s footprint, making it useful for apartments, offices, car travel and public transportation.

Folding designs vary considerably. Some bikes fold across the main frame, while others fold vertically or tuck the rear wheel beneath the frame. Compactness, folding speed, ride quality, weight and durability often involve trade-offs. Small wheels are common, but not every folding bicycle uses them.

A folding bicycle is not simply a small-wheel bicycle, and it is different from a separable-frame bicycle, which comes apart into sections rather than folding on hinges. The category also includes electrically assisted folding bicycles. Manufacturers such as Brompton, Dahon, Tern and Bike Friday have helped popularize the design for urban commuting and travel.
