Bikeray’s IV model has been round for a couple of seasons, but reduced pricing has made it more of a power-for-pound bargain.
The simple barrel-shaped head mount attaches with a chunky O-ring and a curved mount that’s stable enough to keep it fairly secure, even on rough ground. A helmet mount and extension lead are included.
The IV has a pronounced central beam with an outer peripheral halo. Its reach is adequate rather than amazing, and there’s a potentially eye-tiring dim ring between the centre and the halo. That’s pretty much on par for the money though, and is certainly not a deal breaker.
The backlit button on the rear is easy to ﬁnd and use, even when wearing thick gloves, and there is a basic runtime indicator. Battery life is shorter than claimed but still better than most lights of this power or at this price. You can leave it running at full whack for most reasonable rides, which keeps things simple.
Unlike a lot of cheaper lights, the battery bag has an additional strap to stop it sliding around. Bikeray lights that we’ve used long term have been reliable, and there’s a year’s warranty.
