About
What it is.
Brompton's Electric G Line belongs to the brand's folding bicycle family, built around the same fold mechanism the marque is known for but scaled toward a more robust, larger-wheeled platform than the standard line. It serves as everyday transport for city riders who dismount and re-mount frequently, and doubles as compact storage-friendly transport for owners of boats, motorhomes, or vehicles with limited space.
It suits commuters and travelers who want ride quality closer to a full-size bicycle rather than a minimal fold, with pedal assist covering longer or hillier routes. It's less suited to those prioritizing minimum weight or needing to carry the bike up stairs regularly, since the G Line's proportions favor road manners over portability.
The verdict
The Brompton Electric G Line delivers the smooth, stable ride of a full-size bike in a compact folding package, though it sacrifices the light weight that makes traditional Bromptons easy to carry. Best suited for commuters and travelers who prioritize ride quality over portability.

Frequently asked
What buyers want to know.
How does the G Line ride compared to other Brompton electric models?
Reviewers say the G Line has bigger 20-inch wheels and wider tires that give a more stable, full-size-feeling ride than earlier Brompton electric models. The rear hub motor delivers smooth pedal assist that doesn't feel obtrusive.
What's the main downside of the G Line?
The G Line is noticeably heavier to lift and handle than non-electric Brompton models or smaller-wheeled versions. It's also bulkier overall despite folding the same compact way as classic Bromptons.
Who is the G Line best for?
The G Line works well for city commuters, boat or motorhome owners needing compact transport, and riders who want a folding bike that handles like a full-size one. It's beginner-friendly with a comfortable ride position.
Who should skip the G Line?
Skip it if you prioritize the lightest possible folding bike or if you need to hand-carry it frequently up stairs. The extra weight makes it less suited for that use.
How easy is the battery to use?
The removable front-mounted battery is easy to carry and charge separately from the bike, so you can charge it indoors or swap batteries without moving the whole bike.
Can you take the G Line on rough terrain?
Reviewers are split on this. One reviewer treats it as capable off-road, while others focus mainly on flat commuting and leisure trails without testing rougher terrain. Most emphasis the smooth ride on city and casual paths.
