I hope they someday come with electric shifting, wireless if possible. It would be easier to convert from 4 to 12 depending on the situation. There wouldn’t be any need to fiddle with a mechanical rear derailleur and such. I much prefer being able to do that from a phone/computer.

Hi. Brilliant video . Thank you very much for the effort you put in. ❤ I am a true and true roadie, I ride a sweet Orbea Orca. However, I am looking at a Brompton. I think I want 1. Racks 2. Extended rollers 3. Fenders/mudguards 4. A neat solution for lights 5. Rim brakes are fine. Question is, can I just get a Brompton A-Line and upgrade it to have those 4 I mentioned?

Just brilliantly put!

As an owner of 2 Bromptons and a fan of your channel, I find none of your arguments compelling for a G-line. I watched this video 5 times to make sure that I was not missing the point, but how would be the argument "I never owned an e-bike" be an argument for anything, besides mud guards and stuff? I also commute daily, but how would this bike add to my commute? I also own a Tern P10 with disk breaks, which are just higher in maintenance and risk on longer rides. I would assume that the majority of people accept the downsides of a 16 inch Brompton over the so called advantages of this heavy beast with disk breaks any time. If you need a gravel bike, just buy one.

I like minivelos. I own a Moulton. I baby my Moulton so it comes out only in good weather and I don't ride it daily. I like both a Brompton and the Velo-orange Neutrino. Neutrino has the disk brakes and wider range of tires going for it. Where as Brompton has it's compact folded size to just toss it in the boot of my car. Now the G-line combines those two. It looks like a very good option. Hopefully it will come to Finland too. We still are waiting for the electric Brompton. The availability of Bromptons isn't great. Just couple of P-lines came to our shores.

You're spot on with the shifter. I swapped the original 4 speed for a SRAM GX and I never had to re-index nor adjust, not even once. It's been going smooth for over a year. Now that was not the case for the original shifter.

I don't think electric is a good choice for "adventure bike". You'd better off choosing for as many gears as possible.

Bigger Brompton is better. Now it has 20 inch wheels, which makes it definitely better to ride. Folding mechanism is also the same good old, which Brompton has had already a long time. There are certainly details to be critisized, like the small rack..etc, but they are just details which can be changed in the future. The size of Brompton G line when folded is still much smaller than what other 20 inch folding bikes have.

Could this be converted to external gears with a new wheel?

It's the first time I ( hyothetically) would consider a Brompton. I live in a car free city but due to the medieval character there are some cobblestone areas ( 10%). A regular Brompton is pure suicide. That's why, in this class, a Birdy is mileages ahead imho. But, let's see what a G-line offers. Still, I don't put my stock in it. See, with a birdy R20 ( 20 inch) I don't need to hit the breaks when reaching the suicide zones. It's maybe less compact when folded ( although the G line won't be either) but I only need to carry it 1 floor up so..

Have just ‘liked and subscribed’ despite last week you were saying you thought the new G line had been designed on the back of a fag packet and now you have preordered. Nonetheless you are one of the more accomplished Brompton Creators intent on growing your channel and this video might help you back onto Brompton’s Christmas card list. I am excited to see your adventures withe the G line

Good video and I'm looking forward to seeing a G line put to the test and the content you will create. Its too much money for me, so fair play for taking the plunge and placing the order. Hope you do get it as soon as possible 👍

Few months ago I got interested in getting a Brompton. Saw rumors about upcoming G line. And at this point I think I'll get a regular C line. For light city rides and maybe some traveling. Now I have to somehow find a way to get one, since there are no dealers in the country. For serious rides I have a gravel bike. I like it much but almost never using it for affairs in the city because I hate locking it outside.

Hi Dave, great content. One aspect of the electric G-line (EG-line 😁) you could test is the level of drag created by the motor when pedalling with the power off or when when the battery is discharged?????

Brompton needs to expand their line to performance titanium road focused and gravel trail focused bikes with traditional geometry and multi sizes. Generous warranty and semi outrageous prices to match.

I have an M6R that was flipping brilliant in the days when I was commuting into London on the train, but it gets very little use these days now that I'm retired, the roads around where I live in the country are just too rough and it's hopeless on gravel/muddy trails. The G Line looks ideal for me, it would give a much more manageable ride on rougher roads & trails and the slightly larger fold size and weight wouldn't be an issue as it would mostly be transported in a car or on off-peak rail services. I'll be very happy to consider buying one once I can have a test ride. The only challenge I have is that my wife will want one too, so that doubles the price!

you brompton peeps are brainwashed, i have a carerra intercity disc folding bike, tektro hydro brakes, alloy forks, 9 speed sora, hollow axle crankset, 20 inch wheels, good components and frame for 360, orig price was 450. how can brompton charge 5 times as much.

I hope the new battery has a power switch on the handlebar. Shall have to wait to see… 😁

I hadnt realised it was rear wheel motor drive. This i find annoying as i would want a rear hub. In fact this i have on my short wheel base with a 5 speed hub and switch kit. I think it is clear they have done this along with pass through front fork axle to see off Swytch. Id rather buy an after market ti fork and a swytch kit.

I'm sticking with my C-Line. I've never had so much fun on a bike before. I keep fighting my way up the hill without a motor. When I can't go on, I take a short break. I love my Brompton because it's so small. I don't want bigger wheels, a battery, or a motor. But I think it's good that Brompton offers an alternative (bigger tires, motor). PS: I hope Google Translate did a good job.

The G line non electric has a thru axle front wheel so you can’t fit a Swytch kit to it. I don’t like derailleur gears, too much maintenance and easily knocked. Kinetics are already offering an 11 speed conversion for the G line. By buying the Brompton electric version you now have to buy your new motors etc from Brompton. You won’t be happy with 4 gears and will want 6 or 7 -Thus nullifying the Warranty. They’ve put a lot of thought into stopping E-kits from holding their electric version back.

Congratulations on your forthcoming, Brompton, G - Line I look forward to watching the great content you make . 🚵🏽‍♂️

Dave !!! Wow, you're taking the plunge on G-Line electric. I have a few thoughts. Have you seen the "Small Wheel Wonder" KZbin channel? Like yourself, Daniel loves Bromptons. He recently came out with a book, "Maximum Brompton: Building the Fastest Electric Bicycle on 16 Inch Wheels". It's utterly fascinating and he addresses the weaknesses in Brompton's electric offerings. I don't have skin in the game. You're an expert and Daniel is an expert too but you come to different conclusions about Brompton electric bikes. It's my own uneducated opinion that Brompton's hub motor and front mounted battery pack could be a bit antiquated, especially for the price. I'm curious what you think. Noted too is your long commute in inclement weather and your need for fat tires in gravel and muddy conditions. All the best !!! ♥

Why’s the motor on the back wheel on the G line? For 3.5k the motor should be on the front wheel with the Alfine on the rear!

What's the weight difference?

I am tempted for my next ebike. I like the fold up option for storage and getting on the busy trains

I think you are on to something with your hunch that it is the gear-change thumb shifter that is the problem with gear changing. I have recently acquired a 5 speed P Line and after only four weeks the dreaded sloppy gear change reared its ugly head. I have no difficulties changing up and down from gear 2 up to 5 and back down again, but when I try to engage 1st gear the change becomes very "iffy" with only about a 30% chance of hearing it click into bottom gear when I press the lever to downshift. After trying different ways of downshifting eg: quick press-light press- long press and pushing only on the sharp edge of the button, I have found that my method of putting pressure on the edge of the button as I shift down gives me the best result and, so far , is the most reliable method of getting into bottom gear before I lose momentum and grind to an embarrassing stop on the steepish slope that leads to my flat. I am not saying this is a foolproof way of overcoming the problem, but(so far) it works for me.

Went for the manual version myself, given I don't think the battery would be up to what I actually want it for. I know it's still perfectly usable when the battery is out, but the manual version surely outperforms it when put side by side? I don't think I quite have the knowledge chops myself yet to manually change the gearing, like you say. Hehe Hope we get them soon!

Never a G-line! Even as a Standard a G-line is much too large for my cars luggage room, which only and barely holds my now below 9 kilo, Specially modified Superlight, and it is - much too Heavy for me! A Brompton is mostly intended for Transport as folded and not for any actual riding 😄! Finn. Denmark

I hope your bike arrives early too so I get your views of the bike before wifes next birthday 🙂

One factor you missed one thinks = the weight factor = over 32 pounds, compared to the self charging electric Vello titanium folding belt drive bike = doesn’t it make one feel sick that it makes Brompton look so far behind other manufacturers .

The G line medium size reach is too far for my back and neck. Sorry Brompton G line, I wanted to get rid of my modified Giant Escape Disc 2 but with the stem riser I fitted, allows my back in a upright position.

Another influencer using clickbait to get their views up. Thank you for your pointless video based on no actual test rides and using information already in the public domain.

I think this will a successful model in every market where cycling lanes are as bad as in Berlin. What I personally dislike: - the awful cable routing -cheap Tektro brakes -lack of hub dynamo/lights -price (min. €2,800 in Germany) -it’s not as thoughtfully equipped as your “M-Line” built for this price.

Totally agree, not an everyday bike but a weekend expensive one due to the lack of portability!

How is the 12 lighter than the 6? Mad

What kind of accent is this? A bike becomes a bake and so on. Sounds weird to me

Brompton has stolen your idea. You build a rugged Brompton years ago.

Can you review an 18" Kinetics brompton? I couldn't lug a 20" off and on transport but I wonder how well the 18" compromises

I think your video would have benefited a lot if you actually had the experience of testing the bike.

I would buy a G-line Brompton if I couldn't store a regular size bike at home or at workplace away from (most) thieves.

G-line Brompton is the only Brompton that ever caught my eye. The bigger wheels finally make it look elegant and as pretty as my Dahon Speed TR.

Why bother? Just buy a full sized bike.

I got a Brompton 6-speed in 2017. I immediately bought a flat carbon bar for it. This wasn't for weight-saving, but because I hate the feedback/vibration with aluminium bars. Coincidentally Schmolke were the company I bought the carbon bars from. The reason I went with Schmolke was because at that time, they were one of just a couple of companies in Europe that made flat carbon-bars that were compatable with bull-horn bar-ends. Bull-horn bar-ends add a very welcome extra hand positioning for the Brompton, and they don't affect the fold at all. In fact it looks like the bike was designed to fold with bull-horns. I don't know why more people don't have bull-horns on their Bromptons. I hate ergon grips and instead have a double wrapping of cushioned road-bike bar-tape. The bar-tape is also on the bull-horns (double-wrapped of course). Oh, another reason I swapped out the Brompton bars was so that I could add small mirrors to the ends. Therefore I have a small Zefal spin mirror on both ends of the handle-bars (my bike is for commuting in city traffic and mirrors are important). The mirrors also fold out of the way and don't interfer with the folding of the bike. Aside from the handle-bars, I also have quick-release SPD pedals. It's another really useful improvement compared to standard Brompton components. Clip-in pedals make for much more efficient pedaling than non-clip flat pedals.

I may be the odd man out on this one, but I don't like cables going to the rear of folding bikes. I understand if you're going to go touring or whatnot with a folding bike having more than 2 gears is the best way to go about it. And Disk Brakes would probably be the best option. However, for casual commuting with a folding bike 1-2 gears is plenty, and same with a coaster bike for the rear. That's why my Current setup is a 700x35C Montague Boston with a 2 Speed Sturmey-Archer Kickback hub. Right now I need to reduce the chainring size as the hub only increases your gearing 38% in its second gear, and my main issue now is having a lower gear. If after this I need more speeds, I'm getting a Schlumpf Mountain Drive 2 speed bottom bracket for 4 speeds total. Not having any cables going to the rear makes for a quick and easy fold, with no cables on the rear to get snagged on stuff while moving it about folded. Also, it looks clean as hell. Not to mention, I find a coaster brake to be a lot more intuitive for people who mostly have experience with motorcycles, as motorcycles usually have a foot actuated rear brake. For that reason, I set up the bike with a right side front brake lever instead of a left side one, and I quite like it. While the quick fold of the Brompton is nice, having to rely on a chain tensioner for an IGH seems dumb IMHO. I can fold my Montague just as quick with no chain tensioner... Also, Aluminum Forks... WHY? I've had aluminum fail on me suddenly enough times I'd never want to use it as a main suspension material, and I consider rigid front forks to be the main suspension. Hell, the aluminum frame on my Montague isn't preferable, CHROMOLY FTW!

YOUR REVIEW AND YOU ARE ILOGICAL .... 20 INCH TIRE IS MORE LOGICAL THAN 16 INCH TIRE.. YOURE SUCH LOW I.Q.

Haha its not about you, its about the G!

Perhaps mirroring what other folks have said, the G line seems quite appealing to me in North America where the bike infrastructure is quite poor and you are often forced to ride in places that are not quite as friendly to the brompton.

This is a bike in search of a purpose. You mention this being good for touring. I tour with my C line & i disagree. The major advantage of the Brompton is being able to fold it & take it on a plane. My c line when packed in it's case with necessary tools is 47 lbs. The G line will be over the 50lbs limit. Also finding a bag to transport it won't be easy. If you're not taking it on a plane then why a Brompton rather than a less expensive, lghter purpose built touring bike.

Just bought a Brompton m3r used for $1100. Small price to pay to join a cult
