Dahon Helios Folding Bike

The Dahon Helios is a folding bike built on Dahon's patented folding system, a brand with real pedigree in compact bike design. It uses a 20-inch aluminium frame that folds down for storage and transport, making it practical for commuters who need to combine cycling with public transport or have limited space at home or work. The aluminium frame keeps the overall weight manageable compared to steel alternatives, which matters when you're regularly lifting it in and out of a car or up a flight of stairs.

The bike runs V-brakes, the direct pull type that offer straightforward stopping power and are easy to adjust and maintain yourself. They're reliable in most weather conditions and work well for the kind of stop-start riding you'll do in urban settings. The 20-inch wheels are typical for folding bikes, giving you good manoeuvrability in traffic and contributing to a tight fold, though you will need to work a bit harder to maintain momentum over longer distances compared to larger wheel sizes.

This particular bike comes fitted with a pannier rack, which adds practical carrying capacity for commuting gear, shopping, or work bits without needing to wear a rucksack. That's genuinely useful if you're cycling regularly into town or need to move stuff around the city. The fold mechanism takes a bit of practice to get smooth, but once you're familiar with it, breaking the bike down becomes routine.

The Dahon Helios suits anyone looking for a genuine folding bike rather than a full-size one—commuters who use trains or buses, people working from different locations, or cyclists with limited storage space. It's aimed at practical urban riding where portability matters as much as the ride itself. This particular example is listed as a project bike, so it will need servicing and inspection before regular use.
