We review the Cateye Rapid X Rear RC LED Light

Price: £34.99

What they say: The Rapid X pumps out an impressive 25 lumen of almost 360 degree visible light and by using a neat band fitting system, can be quickly and securely positioned on either the seat post or seat stays.

What it is: Cateye are synonymous with quality biking lights and the Rapid X Rear RC LED light is one of the lightest and most effective rear beacons that we’ve used in ages. The slim-line body of the Rapid X secures without fuss to either the seat post or the seat stays thanks to the rubberised waterproof backing and heavy duty rubber band attachment.

When we first pulled it out from the packaging we thought it looked a little flimsy, but after a winter’s worth of rain and drizzle dousing the Rapid X at every opportunity, our initial fears were soon forgotten. The pull-away rubber backing give access to the USB charging attachment and works wonders at keeping any sign of moisture at bay – even without the added protection of a mudguard. Top marks for this.

Charging is a miserly 2hr turnaround (USB lead supplied) and the Li-Polymer battery does a cracking job of pumping out a highly effective 25 Lumen; just what you need on those dark and dreary commutes home. And with no less than five modes the Rapid X goes the distance with a highly impressive range of runtimes. On flashing mode, it seems it wants to go on forever, regardless of how low the temperature gets.

Who it’s good for: Roadies and commuters looking for the security of a lightweight and effective rear LED light but don’t want to waste valuable riding time changing batteries (and who doesn’t?) should put Cateye’s impressive Rapid X RC at the top of their shopping list.
