Overview

Brompton builds the C Line as a folding city bike with small wheels, a rear derailleur on a trigger shifter and a saddle with an integrated carry handle. Fenders, a bell, folding pedals and reflectors come fitted.

Folding shrinks the bike to carry onto trains or store at a desk, and the fitted extras make it ready to ride out of the box. The listing says nothing about the folded size, and small wheels respond differently to rough pavement.

Who it's for

Urban riders on paved roads who want a bike that folds into a car trunk or under a desk. Riders over the weight rating or under the minimum height should check the specs first.

Pros and cons

Pros
  • Compact folding frame
  • Fenders, bell and reflectors fitted
  • Integrated carry handle in saddle
  • Long frame warranty option
Cons
  • Folded size not listed
  • Small wheels on rough ground
  • Six gears only
  • Caliper brakes, not disc

Performance notes

A small wheel and low frame accelerate quickly, and the folding hinge adds a joint that must be locked and checked. Six gears cover city speeds, and caliper brakes stop reliably on dry pavement.
