8 Lightest Folding Electric Bikes 2026: Real Weights, No Marketing Rounding

Folding e-bikes have a weight problem. Bolt a motor and battery onto a bike designed to be carried up stairs or lugged onto a train, and you can end up with something that folds beautifully but weighs like a small dog. I've gone through the current crop of electric folders and pulled out the ones that actually stay light — real kerb weights, not marketing rounding. If you want a folding bike that isn't electric, I've covered the lightest folding bikes here, and if you want a lightweight e-bike that doesn't need to fold, that list is here. This one is strictly folding, strictly electric, lightest first.

Under 14kg — as light as folding e-bikes get

Brompton Electric T Line — the lightest one, full stop

Titanium main frame, carbon forks, and Brompton's own e-Motiq motor system built into the rear hub — the T Line comes in at 13.4kg with the battery fitted, which is genuinely astonishing for an e-bike. Range is up to 56 miles (90km), and prices start from £5,799. It's not cheap, but nothing else on this list gets close to the weight.

17-18kg — full-size ride quality, still genuinely light

Gocycle G4i — the engineering nerd's choice

17.1kg, a front hub motor with proper traction control, and a single-sided fork that makes wheel removal a five-second job. Range is up to 50 miles (80km), and it's priced from €4,499 in the EU. Folds smaller than most, rides bigger than most — Gocycle has been doing this longer than anyone.

MiRider One — the budget-conscious ultralight

17.3kg thanks to a magnesium alloy frame, a 250W rear hub motor with 40Nm of torque, and a thumb throttle if you fancy skipping the pedalling altogether. Range is up to 45 miles (72km), and it's priced from £1,595 — by far the cheapest bike on this list, and one of the lightest. British-designed and assembled, too.

Ahooga Folding Power+ — the Belgian minimalist

17.4kg with motor and battery fitted, a hinge-free aluminium frame that twists rather than folds, and a compact size of 85 x 74 x 30cm once packed away. Range runs to 65km, and prices start from €1,999. Odd-looking in the best way — it's built for people who commute by train as much as by pedal.

Brompton Electric C Line — the one everyone actually buys

17.9kg with the battery on, 14.2kg without it — the steel-framed, non-titanium Brompton electric, and still one of the lightest e-bikes you can buy. Same e-Motiq motor as the T Line, same 56-mile range, priced from around £3,079. If the T Line's price tag makes you wince, this is the sensible version.

Estarli E20.7 — the belt-drive sleeper

18kg, a seatpost-integrated battery that keeps the lines clean, and a 250W hub motor putting out up to 42Nm. Range is up to 30 miles (50km), and it's priced from £1,510. Hydraulic disc brakes and Shimano gearing at this price and weight is genuinely good value.

21kg+ — heavier, but worth carrying

Blaupunkt Fiete — the throttle bike

21kg, but it earns the extra weight with a proper 350W rear hub motor, full throttle assist up to 20mph, and a die-cast magnesium frame that feels sturdier than the ultralights above. Range is up to 44 miles (70km), priced from $1,599. Less about carrying up four flights of stairs, more about not pedalling much at all.

Tern Vektron Q9 — the full-size folder

21.9kg, a Bosch mid-drive motor, a removable battery, and Schwalbe Big Apple tyres that soak up bad tarmac far better than the small-wheeled bikes above. Folds in 10 seconds despite the heft, and rides like a proper bike because underneath the folding hinge, it basically is one. We stock this one — from £2,999.

How to choose a light folding e-bike

Weight on a spec sheet only tells you half the story, so here's what actually matters once you're the one carrying it.

• A battery you can lift out separately makes the bike far lighter to actually carry up stairs — you're not always hauling the full kerb weight in one go.
• Folded size matters as much as folded weight. A bike that's light but still bulky won't thank you on a rush-hour train or under a desk.
• Several of these brands are based in the EU or US, so check UK availability, warranty terms and who does servicing before you buy, not after.
• Think about where the bike will actually live day to day, and how you'll lock it when it's not folded up beside your desk.

The verdict

If weight is genuinely the whole point — stairs, train luggage racks, a small hallway — the Brompton T Line or C Line win, no contest, though you pay for it. If you want light without remortgaging, the MiRider One is the smartest buy here. And if you'd rather have a bike that feels like a bike and don't mind carrying a bit more, the Tern Vektron Q9 or Blaupunkt Fiete are the better ride for the extra kilos.
