I simply had enjoyable driving a Brompton. Precise smile-inducing, adrenaline-fueled enjoyable, on a fold-up bicycle. I’ve ridden many Bromptons, and discover them to be ingeniously transportable feats of commuter engineering, however by no means particularly enjoyable. However right here I’m, careering alongside muddy forest paths, flying up hills and bouncing over tree roots … on a Brompton.
My grin comes courtesy of the brand new Brompton Electrical G Line, probably the most radical redesign within the model’s 50-year historical past. It’s nonetheless unmistakably a Brompton; it nonetheless folds to a 3rd of its dimension, and might be carried (simply) and pushed round prepare stations and subways with ease. However as a substitute of the standard asphalt-friendly, weight-saving 16-inch tires, the G Line has 20-inch comfortable Schwalbe G-One tan wall tires. For all intents and functions, it’s a big-wheel, folding, all-terrain gravel bike.
The handlebars are large, like a daily hybrid bike, and there are disc brakes (the primary time on a Brompton) and a Shimano 4- or 8-speed gear system. It’s accessible in electrical and nonelectric fashions; in Forest Inexperienced, Journey Orange, and Traildust White; and each with and with out rack and mudguards. There’s additionally a selection of small, medium, and enormous sizes. With the usual Brompton you possibly can select the model and top of handlebars and regulate the seat top accordingly, however with the G Line, the ergonomics are tweaked to supply higher stability relying in your top. Simply. Like. A. Common. Bike.
Easy Operator
I’ve been driving the Electrical G Line for 2 weeks, and it simply doesn’t deal with like a Brompton. The wibble-wobble steering has gone, as has the bone-shaking experience over something however easy tarmac. London streets are usually not forgiving, however the G Line soaks up each bump with ease.
That is solely enhanced by the 250-watt rear-mounted hub motor (15.5-mph restrict), which pushes onerous when wanted and removes any effort on the flat. In response to Brompton, the brand new motor was put by way of its paces on a 24/7 sturdiness rig, with greater than 20 motors going by way of a mixed mileage of greater than 1 million kilometers (621,371 miles).
I didn’t fairly handle these numbers, however in real-world circumstances, the motor kicks in easily and helps glide you together with minimal effort. There are three ranges of energy help, every impacting on the bike’s vary, however for me, the midpower possibility gives all the assistance I want, and makes for a enjoyable experience—each on and off street.
The redesigned battery pack clips neatly into the entrance bracket, and gives 345 kWh of energy and a spread of 20 to 40 miles (30 to 60 kilometers). It ejects simply and takes round 4 hours to totally cost. There’s additionally an app, and whereas it wasn’t prepared for my prelaunch check, it can embody over-the-air updates, energy mode controls, distance monitoring, and battery life data.
On the Electrical G Line, a 9-watt entrance gentle and 1-watt rear gentle do job illuminating the street or path forward. There are mounting factors on the elongated entrance set and forks for water bottle cages and packs, whereas the rear rack has ample area for extra baggage. There’s additionally a spread of baggage choices, together with beneficiant satchels with battery storage inbuilt. Will probably be attention-grabbing to see whether or not this bike can carry sufficient for a motorbike packing or touring weekend.
Heavy Lifting
Till now, Brompton constructed bikes for cities. It has bought greater than one million since 1975, and the mixture of teeny wheels and peerless folding mechanism makes them unbeatable for final-mile commuting. In addition they fold up sufficiently small to be taken with you wherever you go. And they should, as a result of a Brompton chained up in London received’t keep chained up for lengthy.
However the G Line isn’t designed for commuters; it’s constructed for trails, and whereas the experience off street is assured, nicely balanced, snug, and silly quantities of enjoyable, the bike is heavier consequently. A small-frame, eight-speed, nonelectric G Line Brompton weighs from 30.6 kilos (13.9 kilograms), which is 6.5 kilos (3 kilos) heavier than a regular mannequin (24.2 kilos, or 11 kilograms). The usual electrical mannequin weighs from 36.6 kilos (16.6 kilograms), and the design I’ve been testing clocks in at 42.9 kilos (19.5 kilograms), together with the battery.

Which means carrying it for any size of time has the potential to be hernia-inducing, and makes the Electrical G Line a bit to hold up and down stairs. The best way the folded body is engineered means the load is not less than evenly distributed, however there isn’t any doubt it is heavy. Sensing this, Brompton has redesigned the rolling wheels to incorporate bearings, making it considerably smoother to push (or pull) than a regular Brompton. If you’ll be taking your Electrical G Line on public transport, be ready to combine up carrying and wheeling to avoid wasting your arms.
That stated, for a folding electrical bike, the Brompton’s weight is in keeping with the competitors. The £2,899 Volt Lite weighs rather less (39.6 kilos or 18 kilograms with battery), as does the £1,299 ADO Air 20, though ADO does have a sensationally gentle Carbon model that weighs simply 27.5 kilos (12.5 kilograms). None of those bikes fold as elegantly because the Brompton although, nor supply the identical huge bike experience expertise.
A Blast to Journey
Whereas nonetheless champions of the folding bike sector then, Brompton is enjoying meet up with the electrical market. And whereas I’m not faulting the efficiency, the battery pack design feels one thing of an afterthought. I sit up for a purpose-built electrical Brompton (in Titanium) when it occurs although.
On first impression I assumed the G Line was unacceptably larger than a conventional Brompton. The tires are bigger and wider, and the body is chunkier, however when positioned side-by-side (see photographs under) there’s not likely an enormous quantity in it—which is exceptional. I used to be frightened about having to retailer the bike at house and take the G Line into an workplace or pub (see earlier remark about London), and whereas it’s heavier to elevate, I don’t suppose anybody will actually discover a lot of a distinction in small doses.

It’s unquestionably probably the most succesful Brompton ever constructed, and an absolute blast to experience, particularly off-road. I’m eager to experience the lightest nonelectric model too, and see whether or not the eight-speed gearing and smaller wheels do sufficient for a severe gravel experience. I believe it would, however whether or not it’s sufficient to tempt severe path riders is one other factor solely.
Which brings us on to, who exactly is the Brompton G Line for? It’s actually a premium proposition, with pricing from £2,395 (my check model prices £3,495), however it’s a Brompton, so many individuals received’t flinch at these costs. For comparability, the most cost effective commonplace Brompton prices from £950, the lightest Titanium possibility prices from £4,250, and the flagship electrical model, the P Line, prices from £3,695. So it is in good firm.
I believe the all-terrain enjoyable will tempt many present fold-up riders off their tiny 16-inch wheels. There is perhaps a compromise on weight, dimension, and transportability, however the experience and dealing with is past comparability.
For the primary time, a fold-up bike has been as gratifying to experience as a full-size design, whereas nonetheless with the ability to fold down and match within the trunk, or below the steps. It’s an outstanding improve and may convey the model to the eye of a complete new viewers.
