Lucas KOTR City 25R rear light



Great all-rounder - literally, with 180° visibility

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

The Lucas KOTR City 25R rear light is the sister to the recently reviewed KOTR 85F front light.

The 25-lumen output is really well used. The LEDs and casing are designed so that the light is very visible from side on as well as from the back. The upshot of this is that you can be better seen when crossing a junction, and from all angles. I found that it was one of the brighter beams out on the road and that's backed up by our light comparator, below.

The KOTR City 25R can be attached vertically to the seatpost, or horizontally onto the back of a basket or similar. The light attaches with a simple silicone gripper strap which I found both simple to use and which stayed in place. This made whipping it off at the end of a ride simple, and the 50g weight meant that it could be stowed in a pocket and forgotten about easily until the end of the evening.

There are three run modes to choose from: bright, a little less bright and flashing. The on/off button was well-placed and easy to operate even with thick winter gloves on. The problem faced with the equivalent front light, namely being distracting to the cyclist herself in flashing mode, is not applicable for the back light.

The KOTR lasted about three hours in a run down test on full beam, but flashing (the light not you) will at least double this. Its 580mAh USB rechargeable battery is a breeze to recharge and the micro USB charge point is well hidden from the elements when out on the bike.

At around 2.5 hours for a full recharge, I wasn't left hanging around waiting to go out. I did have to guess when I needed that recharge, though, as the light went from nice and bright to dead without warning.

I really like the look and design of the City 25R. It is smooth and sleek and doesn't make your bike look like an ill-decorated Christmas tree. If you value the aesthetics of design on your bike, the KOTR will not detract from the sleek lines you have chosen.

In other news, it is also great for attaching to your dog and can be clearly seen through heavy foliage. In case you needed to know that.

The slim line KOTR City 25R rear light boasts an impressive 25 lumen output with 180° visibility to keep you seen from both sides as well as the rear, very effective when crossing junctions. The light can mounted horizontally or vertically on your bicycle, depending on your preference, whilst maintaining 180° of visible light. Plus, the relatively small form factor packs a 580mAh USB rechargeable battery which will deliver 3-6 hours of light from a quick 2.5 hour charge. Simply detach using the integral silicone strap (which leaves no brackets on your bike) and charge via your PC, Laptop or USB mains charger (Micro USB lead included).
