Description
Brompton T Line 1-speed Folding Bike
The Brompton T Line single-speed Folding Bike features a completely new titanium frame, 37% lighter than steel equivalents, giving a noticeable boost to handling, acceleration, and portability. Combined with over 150 weight-saving components, the bike is agile on city streets, responsive on weekend rides, and easy to carry or lift when needed.
Single-speed simplicity for a low-maintenance ride
With a single-speed gear system, the T Line removes the hassle of shifting gears, offering a smooth, consistent ride on flat terrain. This straightforward design reduces mechanical complexity, making it lighter, more reliable, and easier to maintain. Riders enjoy a direct, efficient connection between pedalling power and forward motion, perfect for stop-start commuting or leisurely spins through town.
Compact fold and effortless portability
Despite its high-performance titanium frame, the T Line 1-speed retains Brompton’s iconic 20-second fold. The integrated front carrier block allows the bike to be lifted, stored, or rolled like a small suitcase, making it ideal for trains, offices, or cafés. Lightweight, simple, and practical, the Brompton T Line 1-speed Folding Bike is a no-fuss companion for city commuting and urban exploration.
Handlebar options:
- Low: The straight handlebar. For a sporty, more forward position.
