Tough, weather and waterproof and pretty much thief-proof too, Sparse Cycling Illumination is a must-have for any serious cycler. Forged from die-cast aluminium, there’s none of that irritating rattling on the frame and the LED lighting is so bright that it’s not only a sure fire way to fend off clumsy motorists, but may just fool your brain into thinking it’s daytime. The USB chargeable lithium polymer battery will give you a good four hours of darkness-free riding.
