I’m selling my Brompton C Line 12-Speed. If you’ve been looking for a Brompton, you probably know this is their newest and most versatile model. I bought it recently for my commute, but I’m upgrading to the electric version. This is the 12-speed "Explore" model, which is a total game-changer. It uses a 3-speed internal hub combined with a 4-speed derailleur. It has more range than the classic 6-speed, meaning you can actually climb steep hills without breaking a sweat, but still have high gears for speed on the flats.
