We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.
It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.
If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews
We have read all expert and user reviews on the Brompton Electric G Line. In summary, this is what cyclists think.
10 reasons to buy
- The Electric G Line comes with lights, fenders, and a rear cargo rack that doubles as a kickstand when folded.
- Experts applaud this bike’s enhanced versatility and comfort over traditional Bromptons with 16” wheels.
- The Electric G Line rides more like a full-size bike, with less of the nervousness or vulnerability to potholes suffered by traditional Bromptons.
- When folded, the Electric G Line is very compact for a folding e-bike with 20” wheels.
- Buyers can choose from three sizes, with different stems and seatposts to suit riders from 5’ to 6'6”.
- In one tester’s hands, this bike has no problem tackling cobblestones and a range of loose, uneven surfaces.
- Brompton offers a range of accessory bags that boost the G Line’s value as a commuter or tourer.
- Unlike most e-bikes, the Electric G Line rides well without motor assistance, say reviewers.
- Brompton's warranty covers the frame for seven years and the electrical system for two.
- Reviewers say the hydraulic disc brakes work well.
7 reasons not to buy
- Testers and owners find it hard work to carry the Electric G Line, but it's still light for a 20" folding e-bike.
- The battery gives this bike a front-heavy balance that makes unfolded carrying more difficult.
- A tester finds the rear rack is easily scratched when the bike is folded.
- Reviewers lament the “fiddly” hinges and pedals and say the loose wires can get snagged.
- Testers complain that the battery wobbles around noisily.
- From a standing start, the motor only kicks in after a full wheel rotation.
- This bike’s battery range isn’t massive. Fortunately, the charger is light and compact.
Bottom line
Brompton has given its G Line 20” folder a 250W hub motor and 345Wh battery. While this provides a welcome boost for climbing hills and easier commuting, the Electric G Line suffers from the same compromises as the analog G Line, distancing these models from the unrivalled practicality of their 16” cousins. Yes, the G Line is more versatile and comfortable, and less wobbly than 16” Bromptons. Yes, it rides much like a full-size bike. But is it actually good? The answer to that question depends greatly on each buyer’s particular needs, likes, and budget.Expert Reviews
