Brompton C Line 12-speed

Brompton C Line 12‑Speed Folding Bike

The Brompton C Line 12‑speed is the most versatile version of Brompton’s original steel folding bike, designed for riders who want a single, do‑everything folding bike for city commuting, mixed terrain, and longer urban rides.

Handmade in London since 1975, the C Line combines Brompton’s iconic compact fold with a modern 12‑speed drivetrain, giving riders a much wider gear range than the traditional 2‑ or 6‑speed models — without sacrificing portability.

Why choose the Brompton C Line 12‑speed?

• True all‑round gearing: The 12‑speed system provides a wide, evenly spaced gear range that makes hills, headwinds, and longer distances noticeably easier.

• Compact 15–20 second fold: Folds into a small, locked package that fits easily in condos, apartments, offices, car trunks, and public transit.

• Built for city life: Ideal for urban commuting, multi‑modal travel, and riders who need to carry or store their bike daily.

• Durable steel frame: The C Line’s hand‑brazed steel frame offers a comfortable ride feel and long‑term durability.

• Made in London: Each bike is handcrafted at Brompton’s London factory, maintaining consistent quality and fit.

Who the C Line 12‑speed is best for

The Brompton C Line 12‑speed is especially well suited to:

• Urban commuters with hilly routes or longer distances

• Condo and apartment dwellers with limited storage space

• Riders combining cycling with trains, buses, or car travel

• Cyclists who want one folding bike that can handle flats, climbs, and varied conditions

If you want the classic Brompton ride with maximum flexibility, the 12‑speed C Line is the most capable non‑electric option in the lineup.

Technical Overview

The Brompton C Line 12‑speed uses Brompton’s latest wide‑range mechanical drivetrain to deliver a significantly broader gear spread than the traditional 2‑ or 6‑speed models, while preserving the bike’s compact fold and balanced ride feel. The 12‑speed system combines a rear derailleur with an internally geared hub, allowing smooth, precise shifts across varied terrain — from flat urban streets to longer climbs — without compromising reliability or fold performance.

Built around Brompton’s hand‑brazed steel frame, the C Line 12‑speed maintains the brand’s signature stiffness and durability, offering confident handling when riding and excellent stability when folded or rolled. This configuration is ideal for riders who want maximum mechanical versatility in a non‑electric Brompton, especially those navigating mixed routes, elevation changes, or longer daily commutes.
