No, it’s not April 1st, Brompton, probably probably the most city of motorbike manufacturers, actually has launched a folding gravel bike. Two, really – there’s an e-bike variant too – each below its new G Line banner.
I do know what you’re pondering, these teeny, tiny wheels are going to get swallowed up by the shallowest of ruts, and will probably be unattainable to roll over something bigger than a pebble of pea shingle. Properly, spoiler alert, it’s really quite good – learn on for my first journey impressions.
Brompton says that is the primary main new addition to its platform in 50 years, which is believable. It’s not, nevertheless, Brompton’s first foray into gravel, an honour claimed by its Brompton x Bear Grylls Particular Version mannequin, which turned out to be little greater than its present C Line, with the applying of olive-green paint and hi-viz orange decals.
The brand new G Line is a wholly totally different proposition, constructed from the bottom up for off-road duties, it shares little with the unique Brompton apart from the bikes iconic silhouette, albeit super-sized, and its nifty folding mechanism. Correctly, these brand-defining traits have each been retained.
One of the vital apparent variations is the wheel measurement, which has grown from 16 inches to twenty inches. The pair is shod with fats Schwalbe G-One Allround rubber, in a customized tyre measurement – 20 x 2.1 (54-406) – developed particularly for the G Line. Because the title suggests, these puncture-resistant, tubeless-ready tyres have a positive, non-aggressive, studded tread sample for good traction and acceptable rolling resistance on mild gravel in addition to tarmac. If one element encapsulates the route wherein Brompton is taking the G Line, that is it. Nevertheless, in case your focus continues to be extra city, Brompton additionally affords slick Continental Contact tyres instead.
The inclusion of disc brakes is the subsequent departure for Brompton, a model that also makes use of rim brakes throughout the remainder of its lineup. Impressively, for a folding bike, the TRP-made braking system is hydraulic. So, regardless of the petite 140mm rotors, stopping energy must be potent sufficient for many riders in most situations.
Very sensibly, Brompton has specified Shimano’s Alfine eight-speed inner gear rear hub, which affords a 307% gear vary and retains all the fragile drivetrain parts tucked away out of hurt’s approach. Alfine is low upkeep too, requiring not more than the occasional oil change. Up entrance is a 54t chainring, which seems to be huge, however is a consequence of the small wheels, which decrease the gearing considerably. The handlebar shifter comes courtesy of Microshift.

In profile, the G Line’s metal body seems to be similar to a daily metal Brompton, even the primary tube share the identical 44.45mm diameter. The rear triangle across the dropouts has been stretched right into a D-shape although, to accommodate the disc brake calliper.
Just like the titanium T Line, the fork blades are straight, quite than curved, and have a few bottle cage bosses on the drive aspect.
Brompton hasn’t launched the figures, nevertheless it says the G Line has an extended wheelbase and longer chainstays than its present fashions, little doubt a results of the larger wheels. These geo adjustments ought to make the G Line a extra secure platform for off-roading, although curiously the headtube angle is now barely steeper.
Regardless of the G Line being obtainable in three sizes – small, medium and enormous – all of them share the identical body measurement, it’s the chunky, organically curved stem that dictates which one will fit your needs. It’s provided in one in all three lengths, to present enough stack peak, curving progressively additional away from taller riders to offer sufficient attain. The stem additionally boasts a few bosses for a ‘prime tube’ bag or a further bottle cage.
In keeping with Brompton’s measurement information, a measurement Small is beneficial for riders 5’0” to five’6”, Medium 5’6” to six’0” and Giant 6’0” to six’6”.
The bars are tremendous extensive by Brompton requirements, and close to straight like fashionable XC bars, for degree of management over tough floor. On our loaner pattern, measurement Giant, they measure 65cm throughout. Ergonomic grips are fitted as commonplace, however we now have no phrase on whether or not there can be mid or excessive riser bar choices obtainable sooner or later.
That famously recognisably Brompton attribute, the folding left pedal, has gone, changed by a large platform, quick-release set with pronounced plastic studs for additional grip.
Electrical G Line
Particulars are scant for the electrical G Line, however we do know that the eight-speed Alfine hub is dropped in favour of a 250-watt rear hub motor that works together with Brompton’s Advance 4-speed system. The provided battery delivers 345Wh, which Brompton reckons provides it a spread of 20 to 40 miles.
There’s built-in lighting within the form of a 9-watt beam on the entrance and a 1-watt mild with built-in reflector on the again.
Measurement and Weight
Becoming larger wheels and extra strong tubing makes the G Line much more versatile however there are measurement and weight penalties. Brompton says that the G Line 8-speed in measurement Small weighs 13.9kg, with a rack and mudguards/fenders including one other 900 grams. Our loaner bike in Giant, with rack and mudguards/fenders ideas the scales at 15.2kg. As a comparability, a mid-range, measurement Small C Line mannequin weighs in at 11.35kg.
The electrical G Line 4-Velocity with rack and mudguards weighs 19.5 kg with battery in a measurement Small.
The G Line is significantly larger than the C Line too, measuring 690mm (h) x 730mm (l) x 402mm (w) in a measurement Small, towards 650mm (h) x 585mm (l) x 270mm (w).
The lengthy saddle nostril doubles as a carry deal with, however belief me, you gained’t need to lug a G Line very far utilizing only one hand. The very best approach is to roll it like a suitcase on its outsized curler wheels, guiding it utilizing the raised saddle or prolonged handlebars.
Who’s G Line for?
The G Line opens up an entire new market of rural folks for Brompton, although I think the model is absolutely focusing on urbanites who need to take a motorcycle with them on forays into the countryside by automotive or public transport. It’s an city commuter instrument that’s appropriate for holidays and weekends away too.
In fact, the reverse can also be true, will probably be extremely engaging to multi-modal commuters – rural dwellers travelling into the town by prepare demanding a zippy solution to journey the house to station and station to workplace legs.
Brompton has a loyal following of motorbike packers, a few of whom journey immense distances throughout continents on their little fold-up bikes. They’ll be overjoyed on the versatility the G Line affords, in a single fell swoop the Brompton is not solely the selection of eccentrics. The elevated weight and packed measurement might deter some, nevertheless it ought to nonetheless be doable to fly with it as checked baggage on many airways. The utmost system weight that Brompton recommends is 130kg, together with baggage.
Lastly, some individuals will simply purchase it as a result of they adore its chunky beauty, secure journey high quality and snug tyres.

First rides
My associates, colleagues and household chuckled uncontrollably after I mentioned I used to be going to get a Brompton gravel bike. “The tiny entrance wheel will bathroom down within the first rut it finds, throwing you over the bars,” they laughed. “Good luck with the rim brakes when the wheels get moist and muddy,” they chortled. “The slim bars, no stem and tiny wheels make it the twitchiest bike on the highway, not to mention off,” they tittered. “Good luck attempting to steer that down a gnarly descent.”
Properly, they had been improper. Whereas I wouldn’t want the duty of piloting a daily Brompton down a ‘gnarly descent’ on my worst enemies, the G Line isn’t a daily Brompton. It’s a wholly totally different beast in the case of journey really feel and off-road functionality.
Nevertheless, in nearly each different respect it does behave identical to another Brompton. Unfolding my measurement Giant loaner, in Journey Orange, took me about 5 minutes the primary time I attempted it, however I’m right down to about 20 seconds now I’ve gained the knack of guiding the entrance finish into place with a clean, stirring motion. Folding it again up once more takes about the identical. There’s actually not a lot to it, simply two latches to safe and the seat tube fast launch to fumble with.
It seems to be unmistakably like a Brompton too, just a bit chunkier, extra muscular, extra succesful.
As I already reside within the Cotswold countryside, I assumed I’d throw it a curved ball for my first journey by testing its city credentials. So, off I set down a really busy A40 for an 11-mile round-trip to Cheltenham to get my hair minimize. First, I needed to negotiate Dowdeswell Hill, an extended steepish descent with a mini switchback on the backside, simply earlier than it joins the A40. It’s a preferred Strava phase for locals.
Unsurprisingly, my place on the G Line may be very upright, a consequence of the longer stem on the dimensions Giant, so initially, bowling down that hill, the bike felt very alien. Brompton says it ‘has the journey really feel of a full-size bike for multi terrain’ nevertheless it actually doesn’t. Each second, of each journey, it has been blindingly apparent that I’m perched excessive up on just a little bike with tiny wheels.
As soon as I used to be dialled in although, it felt a remarkably secure place to be. The wheels could also be tiny however they’re 4 inches bigger in diameter than these on a daily Brompton, and so they’re shod with deeper, wider tyres. This, together with the longer wheelbase, wider handlebars and respectable brakes, makes the G Line really feel reassuringly balanced and safe to journey. Positive, it’s misplaced a few of that Brompton agility and directness, however that buying trolley-like twitchiness is gone too. Which is an efficient factor.
Out on the A40, I wasn’t getting side-swiped by the buffeting from fast-moving automobiles and vehicles, which was my largest worry. I shortly realised too that it is a gradual bike to pedal alongside a principal highway, it’s only a case of accepting it and plodding alongside. That is partially because of the gearing, which is a lot low sufficient for ascents however quickly has you spinning out on the flats, regardless of the 54t chainring.
As soon as in Cheltenham, I used to be weaving by the backroads at a greater tempo than the site visitors, and made it to my vacation spot within the centre of city faster than the journey often takes me by automotive. With no parking to fret about, I used to be quickly seated within the salon, my tangerine-coloured confederate safely tucked up beside me.
City testing over, I’ve spent the remainder of my time with the Brompton exploring the lanes, gravel tracks and farmland of the north Cotswold hills. Its eight gears are greater than enough for the ascents right here, however the weight of the bike and the extensive tyres makes progress gradual. It’s extra like an MTB than a gravel bike on this respect.
On the plus aspect, it laps up quick gravel tracks with aplomb. Regardless of my considerations and the convictions of my associates, the wheels roll fantastically over positive to chunky gravel surfaces and so they’re simply sufficiently big to shrug off encounters with ruts and potholes. It’s been fairly moist right here over current weeks, so the paths are simply beginning to get muddy. In these mildly slippy situations, the Schwalbe Allround tyres have hardly ever damaged traction, which is to be applauded.
Pointing the Brompton down barely trickier, looser descents with the odd stretch of embedded rock – I hesitate to make use of the phrase gnarly – is just a little unnerving at first however the little bike finds its approach. Extra consideration have to be paid to line option to hold the wheels rolling, however I discovered this under-biking expertise enjoyable and rewarding. The extensive bars actually assist right here, and, if an extended ascent is approaching, it’s straightforward to drop the saddle out the best way so you possibly can shift your weight over the again wheel.
I did discover three areas problematic. Climbing a steep grassy financial institution stuffed with hoof-sized indentations left by cattle is a problem for any bike nevertheless it proved unattainable for the Brompton, which got here to an abrupt cease, identical to a horse refusing a leap within the present ring. Once more, you’ve received to maintain the wheels rolling always.
Secondly, the pedals aren’t as much as the job. The plastic studs are positive within the dry, however as quickly as my soles received moist, I’d be slipping off the pedals left, proper and centre. If it had been my bike, they’d be the very first thing I’d improve.
Lastly, at 15.2kg my measurement Giant loaner is just too heavy to hold in a single hand over any distance. On clean city surfaces, comparable to tarmac and concrete, it rolls properly however we don’t have a lot pavement within the countryside. Be warned, carrying it on and off trains, planes and vehicles would require energy.
Minor complaints apart, Brompton must be congratulated for constructing just a little bike that basically does bridge the urban-rural divide. It’s the one bike I do know that performs equally properly in each realms – let your outside adventures unfold.
