The T Line is the latest evolution of Brompton superlight bikes. Weighing in at 17.5 lbs, the T Line Urban Low Handlebar features a frame made of titanium, with parts like the fork, handlebars, crankset, and seatpost being made of carbon. The T Line is the lightest Brompton folding bike ever made, and marks their first departure from their iconic steel mainframe.

Brompton folding bikes are made in London and renowned for folding within 20 seconds into a shape roughly 24" x 24" x 12", all while providing a ride that is as comfortable as you'd expect from a normal (non-folding) bike.

The number of potential advantages this packable bike can grant is staggering. If you're concerned about bike theft and also live in a small apartment, it's a bike you can easily bring and store inside with you (and carry up the stairs if need be!). If you have a lengthy commute which is a tangled mess of transfers from bus to train to bus, riding the Brompton can cut down on complexity, allowing you to ride part of the way and stow the folded bike easily on a train or bus. If you travel around the country or world regularly but miss having your bike to explore new places, it's the ideal bike to transport as a checked piece of luggage. If you live in a place where the weather changes and you dislike riding in inclement weather, the Brompton lets you ride when it's nice and easily take the bike home with you in a carpool with a friend or coworker, a taxi, a bus, or a train. The list goes on, but you get the idea. The Brompton is nearly infinitely versatile.

One way in which Brompton ensures a bike with wheels so small is still able to keep up with a typical city bicycle is through the large front chainring. This changes the gearing so that one needn't have to pedal so fast. A unique advantage of the small wheels is quicker acceleration from a stop--which in city stop-and-go traffic comes in handy.

This model is a T Line Urban Low handlebar; a four-speed bike.

Two flat-bar style brake levers control a pair of road style caliper rim brakes. The right brake lever has an attached bell.

As with most of the bikes we sell, this model comes with fenders. Its tires are a pair of Schwalbe One Blacks, a lightweight folding tire with a slick tread pattern for the lowest rolling resistance but is made from a supple, grippy rubber compound for excellent traction.

The saddle included is Brompton's superlight saddle with carbon rails, carbon reinforced base, and lightweight padding.
