The renowned brand currently offers the C Line and lighter P Line models with front hub motors for a boost in the city, with the same collapsible convenience as its regular models. Here’s everything you need to know about the Brompton brand and its impressive folding electric bikes.

What are Brompton electric bikes?
Brompton makes two electric bikes which, just like the rest of the brand’s fleet, can fold down for easy transport and storage. I’ve written before— and at quite some length— just how hard it is to design a good folding e-Bike and whether they’re actually worth it, but Brompton does it right. The Brompton C Line and its lightweight sibling, the P Line, are high-quality folding electric bikes for urban riders and commuters who are tight on space at home or at the office.
Brompton founder Andrew Ritchie began tinkering with his groundbreaking 3-part fold design back in 1975. Bike building and initial growth was slow, but Brompton finally took off in 1987 with investment and its folding bike winning the coveted Best Product Award at the Cyclex Bike Show in London that year. Brompton grew its factory and presence in the UK, later expanding across the globe as the most recognizable folding bike brand. The Dahon brand started around the same time across the pond in the US and also makes Dahon folding e-Bikes, but Brompton still generally marks the gold standard when it comes to the best folding bikes.

Why ride a Brompton folding e-Bike?
Brompton bikes are easy to fold, lightweight, and have a ride feel that’s as close to that of a standard-size bike as you’re going to get. Unlike clunkier or heavier designs from other brands, Brompton bikes collapse down into a very compact package, including tiny wheels to push the bike along when folded as if it were a suitcase. The design challenge is even harder considering there’s a motor and a battery, but Brompton uses a clever detachable battery pack that can be carried as a bag apart from the bike during transit or storage. It’s no wonder that Bromptons have been so popular among city commuters and multi-modal riders for decades— the electrified versions are only the latest chapter.

Brompton Electric Bike Model Comparison
Brompton P Line
The P Line model is about 20% lighter than the C Line, thanks to a high-end mix of titanium and steel rather than a fully steel frame. There’s a 250W motor integrated into the front hub, powered by a 321 Wh battery pack mounted at the front, which can be removed easily for carrying. Even with the electric components, the P Line folds down to around the same compact size as the non-electric version.
Riders can choose between 4-speed or 12-speed setups, along with either mid-rise or higher handlebars. The entire bike weighs just 34-35 pounds. When folded, the bike measures 25.3" by 23" by 10.6", giving it a volume of roughly 6,168 cubic inches— this is exceptionally compact for any folding bike, especially for an electric model.
Perfect for: Urban riders who want the very best (and lightest) electric folding bike out there. Ideal for tight storage, multi-modal transit, and easy carrying up a few flights of stairs.
Brompton C Line
The Brompton C Line is the brand’s classic folding bike, only electrified. It’s built around a robust all-steel frame and comes fully equipped with practical touches like mudguards, dynamo-powered lights, and neatly integrated folding pedals. In terms of performance, it matches the lighter P Line, offering the same motor, battery, and options for gearing and handlebar height.
What sets the C Line apart is its more accessible price point since it sticks with steel rather than incorporating titanium. There are compact 16” wheels and a 250W motor housed in the front hub, paired with a detachable 321 Wh battery. Once folded, it shrinks down to just 25.3" × 23" × 10.6", around 6,168 cubic inches (the same as the P Line and close to that of non-electric Brompton models).
Perfect for: City commuters dealing with tight storage (at work or at home) or multi-model riders taking the train or bus with their bike. Plus, a bit nicer on the wallet.
