C Line vs. G Line: Which Brompton Is Right for You?

Choosing between the Brompton C Line and G Line isn’t about which is “better.” It’s about which one fits your riding style, storage needs, and priorities.

Both are premium folding bikes — but they’re designed with slightly different balances in mind.

Quick Overview

C Line: Compact & Classic Brompton Feel

The C Line is the traditional Brompton experience.

It features:

• 16" wheels

• Extremely compact fold

• Lighter overall weight

• Quick, nimble handling

It’s ideal for:

• Condo living

• Frequent transit use

• Riders prioritizing maximum portability

• Those who value the classic Brompton feel

G Line: Smooth & Confidence-Inspiring

The G Line takes a slightly different approach.

With 20" wheels and a geometry tuned for stability, it offers:

• A smoother ride over rough pavement

• Greater stability at speed

• Improved comfort over longer distances

• Capability on light gravel and mixed surfaces

It’s ideal for:

• Riders coming from larger-wheel bikes

• Suburban or mixed-terrain riding

• Longer recreational rides

• Those who prioritize comfort over ultimate compactness

Fold Size & Portability

If you rely heavily on:

• Tight condo storage

• Frequent folding during transit

• Carrying your bike up stairs

The C Line’s smaller fold and lighter weight may matter more.

If you fold less frequently and prioritize ride feel, the G Line’s slightly larger folded size is often a worthwhile trade-off.

Which Should You Choose?

Choose C Line if:

• Compactness is your top priority

• You commute with transit daily

• You want the lightest traditional Brompton

Choose G Line if:

• Comfort and stability matter most

• Your routes include rough pavement or gravel
