Best folding exercise bikes for a flat: six X-frame bikes compared on levels, weight limit, footprint and weight
A folding exercise bike is the gym kit that fits a British flat: it stands behind a door when folded and is quiet enough for a neighbour below. The figures that matter are the resistance levels, the maximum rider weight, the footprint in use and folded, the bike's own weight, and whether there is a backrest. Six X-frame bikes, from a 14 kg budget fold-up to the 23.5 kg Sunny with an app.
