Overview
The C Line 6-Speed is Brompton's hand-brazed steel frame folding bike, built in London, folding to a locked package in under 20 seconds and weighing 26.4 lbs with a 7-year frame warranty.
This is a commuter and multimodal-transport bike rather than an all-day touring or hill-climbing machine, a distinction reviewers themselves draw. The price sits well above typical folding bikes, but owners consistently frame it as buying design engineering and build quality rather than just a bike.
- Hand-brazed steel frame, built in London
- Folds to a locked package in under 20 seconds
- 26.4 lbs with a 7-year frame warranty
- Choice of Low, Mid, or High handlebar position
Who it's for
Suits city commuters who combine cycling with transit, storage under a desk, or car trips, where the fold matters as much as the ride. Not the pick for all-day rides or serious hill climbing, by the reviewers' own account.
What buyers say
From Amazon customer reviews.
Owners repeatedly called it well-built and worth the price for city commuting and multimodal travel, with one praising the customer service response when a clamp handle arrived broken. A separate reviewer found rust on the inner tube on arrival, and more than one noted the gears take some getting used to compared to a standard road bike.
