Dahon folding bike

This is a Dahon folding bike with 20-inch wheels, built around the brand's established folding system. It uses an aluminium alloy frame paired with V-brake direct pull brakes and derailleur gears for gear changes. The compact fold makes it suited to urban commuting, particularly for riders who need to combine cycling with public transport or storage in tight spaces.

The 20-inch wheels keep the folded package reasonably compact, and the derailleur gearing means you've got multiple ratios to work with across varied terrain. V-brakes are straightforward to maintain and adjust, offering reliable stopping power in most conditions. Day to day, this kind of folding bike works well for short to medium urban trips where you need to get the bike on a train or store it indoors without taking up much room.

Note that this particular bike needs a new front wheel, so you'll need to factor in the cost and effort of replacing it before it's ready to ride. Once sorted, it's the sort of bike that handles the practicalities of city cycling reasonably well—the fold becomes routine once you've done it a few times, and the compact size makes it genuinely portable compared to full-size bikes.
