The Best Brompton Electric Folding Bikes: Our Selection
For decades, the British brand Brompton has reigned supreme in the compact folding bike category. No one has really taken that title away from it. With the introduction of its electric models, the brand has pulled off a remarkable feat: bringing its legendary status into the era of e-bikes without losing any of its DNA. In this article, we’ll trace Brompton’s origins, break down its electric assist system, and review the five electric models that are truly worth considering today.
Key points to remember
- Brompton combines its iconic compact folding design with electric assistance built to last.
- Each model is designed for a specific purpose: light urban commuting, hilly terrain, or more adventurous outings.
- A removable battery, record-breaking folded size, and a variety of finishes: the electric Brompton remains a flexible and smart city bike.
The Brompton Brand
Brompton Bicycle was founded in 1975 in London by Andrew Ritchie. The original goal was simple yet ambitious: to build a bike that would enrich your city life, rather than limit it. The result is an ingenious three-part folding system that remains the industry standard to this day. A Brompton folds down smaller and faster than almost any of its competitors, allowing it to slip effortlessly onto a train, into a car trunk, or under a desk.
Electric Assistance on the Brompton Side
Brompton categorizes its bikes into several lines based on frame material and technical specifications. Here are the five electric models worth considering, each designed for a specific type of rider.
Train stations are full of obstacles: stairs, turnstiles, and high steps on trains. Every kilo counts when you have to carry your bike. While a standard e-bike can easily weigh close to 25 kilos, the comfortable weight range for a folding bike designed for train travel is typically between 14 and 18 kilos. Manufacturers achieve this by using high-end aluminum, magnesium, or carbon fiber.

Our Top 5 Brompton Electric Folding Bikes
Brompton Electric P Line (Explore 12-speed)
The P Line is Brompton’s premium line, featuring a meticulously crafted frame and high-end components. It combines a steel main frame with a titanium rear frame and fork. This Brompton P Line Electric refurbished is equipped with a 12-speed drivetrain (a 3-speed hub combined with a 4-speed derailleur) and weighs approximately 12.7 kg without the battery. The 250-watt motor is powered by a 300-Wh battery, housed in a compact bag that clips onto the front of the bike.
Honestly, it's the ultimate all-around bike for demanding commuters and weekend cyclists. Thanks to its 12 speeds, this model handles hilly terrain and longer trips outside the city with ease, while its light weight makes it easy to carry onto train platforms.
Brompton Electric C Line (Explore 6-speed)
The C Line is the classic, all-steel Brompton—the backbone of the electric lineup. This Brompton Electric C Line Explore refurbished features a hand-welded, puncture-proof steel frame and the traditional 6-speed drivetrain, which offers a wide range of gears for everyday use. It weighs approximately 14.5 kg (excluding the battery) and offers a range of 30 to 70 km, depending on the assistance level and road conditions.
It’s the logical choice for the everyday urban cyclist—the one who values reliability and durability over saving a few grams. A perfect companion for your daily commute on flat or slightly hilly terrain.
Brompton Electric P Line (Urban 4-Speed)
For those who prioritize speed and a lightweight bike for city riding, the P Line Urban is the sharpest choice. Like the Explore model, it features a lighter titanium rear frame, but the drivetrain has been simplified to an ultra-lightweight 4-speed derailleur. The result: less mechanical resistance, less weight, and more responsive handling that reacts instantly to every pedal stroke.
A model designed specifically for strictly urban use on relatively flat routes. Ideal for commuters who often carry their bikes up stairs and enjoy a sporty, dynamic ride in a bustling city.
Brompton Electric C Line (Urban 2-Speed)
This is Brompton’s most minimalist—and most affordable—entry-level model in the electric bike segment. This C Line features an all-steel frame with just two gears: the motor compensates for the lack of gear ratios when starting out or on gentle climbs. By eliminating the more complex hub gears, the bike is easier to maintain and lighter than the 6-speed version.
This model is perfect for cyclists looking for a simple, no-frills electric folding bike for short, flat rides around town. In my opinion, it’s an excellent choice for anyone who wants to avoid the complexity of too many gears and relies on the motor to do most of the work.
Brompton Electric G Line (the next-generation folding bike)
Brompton’s latest innovation deliberately breaks with certain design conventions to offer greater comfort and versatility. This refurbished Brompton Electric G Line rides on 20-inch wheels (compared to the usual 16 inches) fitted with wide, high-grip tires tires. It features hydraulic disc brakes for powerful stopping power in all weather conditions, and its sturdier frame offers geometry that closely mimics the handling of a full-size bike.
Cyclists who like to venture off the beaten path will find a bike here that’s built for unpaved trails, gravel, and bumpy cobblestones. It also offers greater stability and comfort on long rides, even if it’s not quite as compact when folded as other models.
Comparison of Brompton Electric Models
| Model | Weight (without battery) | Speeds | Autonomy | Ideal Profile |
|---|---|---|---|---|

| C Line Urban | Lighter than the 6-speed | 2 | Depending on the type of assistance | Short, flat routes; tight budget |

Dieter's Tip
In my opinion, don't let yourself be mesmerized by the lowest number on the scale. The real test is your actual ride: if you never stray from flat pavement, the C Line Urban does the job just fine for much less than a P Line. On the other hand, if your route gets a little hilly or longer, you’ll quickly notice the extra gears on the Explore—and no spec sheet can tell you that better than a real ride.
Conclusion
Brompton’s electric folding bikes combine functionality and electrification with an iconic folding design. The British brand has wisely retained its proven design while housing the heavy, removable battery in a bag attached to the front—keeping the bike itself easy to carry. With the arrival of the lighter P Line and the sturdier, larger G Line, Brompton now offers a model suited to every type of rider. Whether you’re tackling a hilly route with the 12-speed Explore or prefer the simplicity of an urban model, an electric Brompton remains a solid investment in flexibility, durability, and the joy of everyday riding.
