Niterider’s latest lights offer blinding science and some unique features but their practical performance and value are less brilliant.
This single LED light has a well-focused beam for plenty of throw and detail a long way down the trail. There’s a battery indicator for the long run time and the default settings can be modified online via your PC and the charger.
Peripheral vision is restricted though, and it’s not great for helmet use thanks to a forward mount that strains your neck. The hefty adjustable arm bar mount waggles over rough ground too.
We’ve had ignition problems with both our samples and the leads still pull apart easily. It’s as heavy on the wallet as it is on the bike.
