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.
