It feels like an eternity since I first encountered the Brompton G-Line in person during the launch event at Brompton Junction London back in September of the previous year. Upon leaving the event, despite not having taken one for a test ride — that opportunity arose a few days later — I had an inkling that it would be an ideal fit for me. Subsequently, I placed an order, and just prior to Christmas 2024, it was delivered. I have utilised it almost exclusively since its arrival and have covered several hundred miles. I deemed it an appropriate moment to proffer my long-term assessment of the bicycle, so here goes.

Ride Quality
I have never had anything adverse to say about my smaller-wheeled Brompton bicycles and have quite happily navigated the most treacherous roads in London and beyond without issue. I have accomplished rides exceeding 100 miles on my smaller-wheeled Brompton bikes and have been thoroughly satisfied. However, the G-Line elevates the experience.
The combination of the larger 20-inch wheels, wider handlebars, and the riding position all contribute to a comfortable experience. It seems that nothing can unsettle the G-Line. Potholes, cobbles, gravel, grass, canal towpaths, riverside tracks, country lanes (the list is extensive) are effortlessly tackled. The 'G' in G-Line could also stand for 'glide'; it truly glides along with grace. I did not acquire the G-Line for rugged gravel riding or for that absurdity of carrying tents and bin bags to sleep outdoors like a Sociology teacher in the early 1980s! I procured it for adventures in and around London, and while I recognise it is also excellent for occasional off-road riding, it is splendid for the activities I get up to.
Size and folded package
I do not reside far from the tube line, but I can also choose to cycle into central London if I so desire. Since acquiring my G-Line, I have utilised the tube more than I have for some time. I intended to ascertain what it was like at as many different times of the day as possible. I have not encountered any significant issues when navigating my G-Line on or off the tube or trains; however, it is a heavier bicycle and has a larger folded package. My regular Brompton bicycles are more appropriate for this, as they are lighter (my Brompton Electric is approximately the same weight as the G-Line). If I were to use public transport regularly as part of my commute, the standard-sized Brompton might be a more advantageous option.
Cycling over greater distances
The furthest I have cycled so far on my G-Line is just shy of 80 miles. I have not experienced any ill effects from this, and rides of 40 to 60 miles are handled with ease. As I mentioned, its riding position is very good, which contributes to the overall ride quality. However, I would like to offer one caveat: I swapped the off-road Schwalbe One tyres for Continental Urban tyres. For me, this instantly improved the ride on the road. They rolled better, allowing me to pedal with less effort and at a higher speed. Consequently, this made longer rides more enjoyable. I am not sure that I would want to take my G-Line on a 60-mile nocturnal adventure using the off-road tyres that come as standard with the bike.
Gearing
The G-Line comes equipped with a 54-tooth chainring and an Alfine 8-speed hub, ensuring that gear changes are executed swiftly through the up and down shifters. In my experience, I have found the G-Line to be very similar to my traditional Brompton bikes, which feature a 44-tooth chainring and 6 speeds. Notably, the G-Line demonstrates comparable—if not slightly superior—performance on inclines, likely attributable to its larger diameter tyres and more favourable riding position. On level terrain, while its performance is very good, I perceive that I can attain slightly higher speeds on my standard Brompton bikes. Nevertheless, it is important to clarify that my cycling is not competitive, and the G-Line's gearing functions effectively for my needs.
It is worth noting that the G-Line carries a significant price premium compared to the standard Brompton. For the same investment, one could opt for the lighter P-Line. Ultimately, the decision hinges on the frequency with which one must navigate stairs in underground stations. Personally, I regard the G-Line as a worthy investment; I have utilised it more than any of my other Brompton bikes. Despite contemplating a change, I constantly find myself returning to the G-Line.
That something you can't put your finger on
All of my Brompton make me happy (and sometimes elicit the same from passers-by), yet there is an undeniable charm about the G-Line. The ride experience is exceptional; it glides almost silently, offers comfort, and performs admirably on uneven surfaces or, dare I mention, off-road. I have acquaintances who champion the electric version, providing an option for those in need of additional assistance. While G-Line is heavier, boasts a larger folded size, and lacks the agility of my standard Brompton, I cannot envision my cycling life without the G-Line now that it has become part of my fleet.
Well, there you have it dear reader. I am sure that you will see my G-Line appear in many more adventures over the next few months and yes I am rather fond of it.
Until next time, stay safe out there people!
