Overview
A 12-speed folding commuter bike with a hand-brazed steel frame that folds to a compact size in about 20 seconds. Built for city riders who need to carry the bike onto trains, under desks or into small storage spaces.
Brompton's fold is the whole point here: at 26.4 lb the bike is light enough to lift and roll like a suitcase, and the compact package is what separates it from a standard commuter bike. The 12-speed drivetrain adds range for hills and longer rides compared with Brompton's lower-speed models, and the steel frame carries a 7-year warranty.
- Folds in about 20 seconds
- Hand-brazed steel frame, 7-year warranty
- 26.4 lb with Schwalbe Racer tires
- Three handlebar height options
Who it's for
Urban commuters who need to combine cycling with public transit, car storage or office space limits. Not the choice for riders who want a lightweight bike purely for speed or off-road use, since the fold mechanism and steel frame add weight compared to a dedicated road or gravel bike.
Strengths and trade-offs
Drawn from this product's published specifications.
- Folds to a compact size in about 20 seconds
- Minimal assembly, just attach the saddle
- 12-speed gearing handles hills and longer rides
- 7-year frame warranty
- Steel frame and fold mechanism add weight versus a dedicated road bike
- Premium price point for a folding commuter bike
Performance notes
The 12-speed gearing gives more range than Brompton's simpler 1-, 2- or 6-speed models, which matters for hills and longer commutes rather than flat, short trips. Setup out of the box is limited to attaching the saddle, and the hand-brazed steel frame is built for repeated daily folding rather than being a one-time trick.
