To me, the standard 16" Brompton excels mainly in its foldability and not much else. As a city bike, I would prefer something like a B75 upgraded with lightweight components, similar to what is seen in Chapter 3. I would upgrade it with a comfortable saddle, like the Fabric Scoop Gel, and EE brake calipers. I’d also want lighter wheels similar to the 14 spokes Roloff wheels on the old Dahon Kinetix, a 6069 seatpost (like a Thompson), Ergon MTB XC grips, SRAM Red crankset, and fast tires.

While it's certainly possible to go on a proper gravel ride with the G Line, I find it better suited for a minivelo like the Dahon Dash. However, I would still prefer my race gravel bike or even my all-road bike. The gravel bike and G Line are similar in weight, so carrying or pushing either on difficult terrain will feel comparable. Yet, the gravel bike offers better rolling speed and performance.

In my opinion, the G Line targets a niche market. What advantages does the G Line offer that a standard Brompton does not? For £2.5K, I would rather invest in a standard Brompton and an aluminium gravel bike.
