Brompton T Line Urban 4-Speed

$8,200.00

The Brompton T Line Urban – 4 Speed is the pinnacle of lightweight folding bike design. Built from titanium, it’s 37% lighter than steel yet delivers durability and performance for city riding. The 4-speed drivetrain offers just the right range for accelerating, cruising, and climbing, while the compact fold takes you from street to sidewalk in under 20 seconds.

Expertly TIG-welded in Sheffield, each frame carries its own signature weld, highlighting the craftsmanship behind its gunmetal finish. Portable, resilient, and fast, the T Line Urban makes urban mobility effortless.

Note: as Autumn approaches, we carry less in-house inventory and count on Brompton USA’s warehouse for rapid delivery – learn more here and see Brompton USA stock and place a preorder here.
