Brompton folding bike 5 speed– Titanium and lightweight Upgrades

This is a British-made Brompton folding bike that's been significantly upgraded and customised over its 13-year life. It started as a 6-speed machine but has been converted to a 5-speed external derailleur system, swapping out the heavier internal hub for smoother shifting, more efficient power transfer, and simpler maintenance. The lightweight approach carries through the entire build—roughly 80% of the standard fittings have been replaced with titanium fasteners, which keeps overall weight down without compromising durability. A Lightpro crankset and removable pedals help keep the folded footprint as compact as possible, which matters if you're regularly carrying this through train doors or up office stairs.

The bike comes with extendable stabilisers (Eazy wheels) that provide a wider stance when the bike is folded or being used in trolley mode, making it easier to manoeuvre when it's not being ridden. The 16-inch wheels and caliper side-pull brakes are standard Brompton fare, proven in thousands of urban commutes. The 5-speed gearing gives decent range without the weight penalty of more speeds, and it shifts decisively with the external derailleur rather than the notchy feel of an internal hub.

The bike was resprayed at some point and has been ridden regularly since its original purchase via eBay, so it shows its age honestly. What makes this particular machine stand out is the bundle of original spare parts included with the sale—the original rims, Sturmey Archer gearbox, handlebars, and various other components. This means you can return it to factory configuration if you ever wanted to, or keep the lightweight titanium upgrades as they are. It's a practical commuter that folds down tight and a genuinely fun ride around town, but the owner's commute has changed and it's surplus to requirements now.
