Folding Mountain Bike

These two Challenge folding mountain bikes offer practical compact transport with a steel frame and 26-inch wheels. As folding bikes, they collapse down for storage or carrying on public transport, making them suited to mixed commuting where you need to combine cycling with train or bus journeys. Both have been used and haven't seen action for a couple of years, so they'd benefit from a service before regular riding—typical checks like cable tension, brake adjustment, and general drivetrain cleaning would get them running smoothly again.

Each bike runs a 21-speed derailleur gear system, which gives you decent range for varied terrain and gradients. The centre-pull caliper brakes are straightforward and reliable, though they'll need checking and adjusting as part of any pre-use service. The steel construction is solid and durable, though it does mean these bikes carry a bit of weight compared to aluminium alternatives—worth considering if you're regularly folding and unfolding them for transport. The green colour is practical for visibility on the road.

The 26-inch wheels strike a balance between manoeuvrability and rolling efficiency, typical of mountain bike design. This wheel size also helps keep the folded package relatively compact. Day to day, you'd find these bikes comfortable for shorter to moderate rides, with the folding design making them genuinely portable if you need to stash one under a desk or into a cupboard when not in use. They're straightforward, no-nonsense machines rather than lightweight performance bikes, which means they're forgiving to ride and won't demand much fussing about.
