Overview
The Brompton C Line 2-Speed is a hand-brazed steel folding bike built in London, folding into a compact package in under 20 seconds and weighing 25.4 lbs. The 2-speed drivetrain is set up for flat city riding, backed by a 7-year frame warranty.
Two speeds keep the mechanism simple, but that simplicity means hills call for different gearing than what ships stock. Brompton positions this as an urban commuter first, an all-terrain option second. The compact fold is the whole point here, not raw speed or climbing ability.
- 25.4 lb hand-brazed steel frame
- 3 handlebar height options: Low, Mid, High
- Ready to ride with saddle attachment only
- 50 years of London manufacturing
Who it's for
Suits commuters riding mostly flat routes who need a bike that folds small enough for a train, an office corner, or a car trunk. Riders who face regular hills should look at a wider-range Brompton model instead.
What buyers say
From Amazon customer reviews.
The one detailed review calls the fold and build dependable but flags two weak points: the 2-speed gearing is tuned for flat commutes only, needing a front chain ring swap for hills, and the stock brake pads are described as barely adequate, with the reviewer planning to switch to aftermarket pads. Stock pedals were called adequate for smaller feet but inefficient for larger ones.
Strengths and trade-offs
Drawn from this product's published specifications.
- Folds to a compact, carryable package in under 20 seconds
- Hand-brazed steel frame backed by a 7-year warranty
- No assembly beyond attaching the saddle
- 2-speed gearing suited to flat terrain, not hills
- Stock brake pads described as barely adequate
- Stock pedals work poorly for larger feet
Performance notes
The hand-brazed steel frame and Schwalbe Racer tires carry Brompton's usual ride quality, and the fold-to-carry sequence takes under 20 seconds once practiced. The 2-speed hub is tuned for flat ground, so climbing performance depends on swapping the front chain ring or choosing a wider-range Brompton variant.
