For a long time, the name Brompton was practically synonymous with folding bikes. People simply referred to their folding bike as "a Brompton," and those in the cycling world immediately understood what they meant. However, the Brompton lineup has evolved significantly. Today, there are not only four distinct levels of Brompton bikes, but also electric versions available. Beyond the standard C Line, there's also the high-end, titanium T Line, and even a whole lineup of electrified Brompton bikes. What might be the most interesting bike, however, is this Brompton G-Line. This Brompton initially felt like a folding bike trying to chase the ever-popular gravel bike segment. However, I think this is my favorite version of the Brompton folding bike formula I’ve tried yet.
