Our verdict
Brompton makes folding electric bikes for city riders who have nowhere to store a full size bike and want support from the company that built it. The price asks for that: entry sits at £2,999, which keeps Brompton well away from the cheapest e-bikes on the market.

Pros and cons
Pros
- The removable battery comes out for charging, and the pack tops out at 345 Wh for a claimed range of 90 km.
- A 7 years frame warranty alongside 3 years on the battery means the frame should outlast the pack by a wide margin.
- Service is handled in house through a own service network, so the same firm that built the bike looks after it.
- A 28 day money back window lets buyers check the range claim on their own routes before committing.
- Support reaches buyers on chat, email and phone, covering phone and chat as well as email and a help centre.
Cons
- The hub motor is rated at 250 W, well below the e-bike median 500 W, so steep climbs ask more of the rider.
- Battery capacity tops out at 345 Wh where the folding class median is 429.5 Wh, so long rides run out sooner than on bigger packed rivals.
- Even the lightest bike in the range weighs 13.8 kg, so stairs, lifts and train platforms still take a load.
- The listed market is GB, so buyers outside the UK have no listed local service base to rely on.
Who it suits
- Riders with a hallway, a cupboard and no garage who need one bike for both the street and the train, with the lightest bike at 13.8 kg.
- Buyers who plan to keep a bike for a long time, since the frame warranty runs 7 years and the servicing stays with the maker.
- Shoppers ready to pass on a cargo bike from Tern and a full size e-mtb from Kalkhoff in favour of a single folding platform.
Who should look elsewhere
- Anyone chasing long range or steep climbs, since the motor is rated at 250 W and the pack stops at 345 Wh.
- Buyers who want a city, hybrid, step-through or e-mtb frame, where Kalkhoff (city, hybrid and step through) covers those shapes and Brompton folds only.
- Riders outside GB, and anyone weighing a fat tyre, since HK BEIRUI TRADE CO. lists commuter, folding and fat tire.
Pricing
Four reference models make up the electric line: the Electric C Line, the Electric G Line, the Electric P Line and the Electric T Line. Prices start at £2,999 and reach £5,799, in pounds, and the model names stay the same across that spread, so a buyer picks a budget rather than a different format. The distance between the two ends is wide, so there is room to move up the range without leaving the folding platform.
Where it sits among rivals
Ranked on entry price, Brompton sits at 140 of 149 brands, and at 130 of 145 on the top price. Both places sit well down the tables rather than near the front, which is the pattern of a brand priced above the mass of e-bikes. The gap between the entry and top figures also means buyers travel a long way through the range from a high starting point.
What it does well
Every electric Brompton has a removable battery, and the pack tops out at 345 Wh, which pairs with a claimed range of 90 km. Because the pack lifts out, it can be charged indoors rather than beside the bike, which suits flats and shared stores. The frame carries 7 years of cover and the battery 3 years, so the pack is the part most likely to need replacing inside an ownership life. Finance is available for buyers who would rather spread the cost. A 28 day money back period gives room to judge the range claim on a real route, and the lightest bike in the range still weighs 13.8 kg.
Who runs it
The legal entity is Brompton Bicycle Retail Limited, headquartered in the United Kingdom and trading since 1975. Buyers reach the company on chat, email and phone. One firm handles the sale, the warranty and the help desk, so a fault does not have to be passed between the shop, the maker and a repairer before anything moves.

Frequently asked questions
How far does it go on one charge?+
Brompton quotes a claimed range of 90 km for the electric bikes, with the battery topping out at 345 Wh. That is a manufacturer claim, so real distance follows terrain, load and riding position. A 28 day money back period gives buyers space to check the figure against their own route.
Can the battery be taken out?+
Every electric Brompton has a removable battery, and the pack holds up to 345 Wh. Lifting it out means charging indoors rather than hunting for a socket near the bike, which suits flats and shared stores. Removable packs are standard in the folding class at 100%, so the benefit is expected rather than unusual.
What warranty comes with the bike?+
The frame carries 7 years of cover and the battery 3 years, so the frame should outlast the pack by a wide margin. Add the 28 day money back window at the start for buyers who want to check the claimed range before keeping the bike long term.
Can I pay in instalments?+
Finance is available, so the cost can be spread rather than paid in one go. The same company runs finance, sales and servicing, which keeps the arrangement inside one firm. The price still starts at £2,999 and reaches £5,799, so an instalment plan changes the timing of payment rather than the cost of the bike.
Which motor does it use?+
Brompton fits its own hub motor, rated at 250 W, with the drive in the hub rather than at the crank. Hub placement suits a folder because the frame stays simple when folded. Against the wider e-bike market, where the median rating is 500 W, the figure is modest, so the help is gentle on flat city streets rather than strong on climbs.
Is the battery certified, and what brakes are used?+
The battery is certified to ul 2849, and the Electric G Line uses hydraulic disc brakes. Certification covers the electrical side of the pack, while the brakes do the stopping on the road. Together these are the two parts riders ask about most on an electric bike bought for daily use.
How heavy is it, and where can I buy one?+
The lightest bike in the electric range weighs 13.8 kg, so it is still a load to lift onto a train or up stairs. Bikes are listed for GB, sold both direct and through dealers, and servicing runs through a own service network rather than a partner chain.
