Keep your wheels turning when you have the Pocket Bicycle Multi-Tool to hand. A nifty bit of kit with a ball-end hex key set, chain breaker tool and socket tri-tool, plus other essential instruments, all folding neatly into a wooden centre. It may be small but it's definitely strong - the tools are coated in titanium and held firmly in place with chunky bolts. Stores away in its own wooden box and measures 92 x 62 x 28mm.
