5 of the best folding bikes

Pacific Cycle IF Mode

£1700, folding-bikes.com
The IF comes close to the amazing bikes of the future promised to us in '80s TV shows such as Street Hawk. It uses built-in magnets to bind the wheels together and the bike's chain is encased in a grease-free, folding-arm, aluminium body that looks as if it could probably fly. Rolling the slimline frame is a doddle but the magents which hold the fold together are a bit weak. Sexy, clever and fast – better gears would make it a winner.
