Clever Cycles • Brompton Electric G Line 4 Speed e-Motiq

  • Details That Matter

    Hydraulic disc brakes offer stopping power in wet conditions. Wide handlebars give control over rough terrain. The electric system integrates seamlessly, and thoughtful touches like rack, mudguards, and lights come included so you can ride immediately.

  • Is This Your Bike? Read On.

    Riders who want a single bike that adapts: daily commuters who ride through mixed terrain, weekend adventurers, or anyone who values the power of an electric boost combined with portability. If you need an e-folding Brompton for everything from city streets to gravel trails, this is your match.

  • Pure Brompton

    Because every part of this bike was engineered in unison — from the frame geometry to the electric system — it delivers urban agility and off-road ruggedness without compromise. The 20” wheels, full disc brakes, and Brompton’s signature fold work together so you can ride hard, stash it quickly, and trust it to perform.

Brompton G Line Size Information

The G Line changes the equation. It comes in three frame sizes — Small, Medium, and Large — based on your height. The geometry, stem, and seatpost lengths were developed with professional bike fit experts to ensure comfort and stability for every rider.

Here's a general guide:

Rider Height Recommended Size
4′10″ – 5′6″ Small
5′6″ – 6′0″ Medium
6′0″ – 6′5″ Large

If you're between sizes, choose based on your preferred posture: smaller for more upright comfort, larger for more stretched efficiency.
