David Millar — former pro-cyclist and current owner of the bicycle clothing brand CHPT3 — approached Brompton back in 2015 with the idea to make the ultimate urban folding bike. The partnership resulted in what was originally just going to be a series of prototypes. But when both brands realized what they had, there was no choice but to release it to the public.

The first Brompton x CHPT3 collaboration debuted in 2018 and has since produced three more versions, with the most recent coming out this past week. Added to Brompton’s mid-level P Line, the 4th Edition folding bike broadens the scope of what this partnership is capable of. Not only can it serve as a fun and functional commuter bike but can also be a solid everyday option if you so choose.

With titanium parts on the frame’s forks and rear triangle, as well as lighter Tubilito inner tubes, the super-narrow 4-speed bike is now over 3.3lbs lighter than the original model, clocking in just shy of 21lbs total. The tan-walled Schwalbe One tires allow for better traction on the pavement and the ergonomic fi’zi:k Terra Argo X5 saddle absorbs shocks and minimizes noise. For rainier commutes, the drainage channels give this model even more versatility.

The Brompton x CHPT3 4th Edition bicycle is now available from Brompton’s website for $3,200.
