The Cateye Nano60 Rear Bike Light is neat little product that delivers a lot of lumens for little weight, outlasts its claimed run times and mounts to round and aero seatposts. But it offers little visibility from the side and the water resistance is less than offered by a lot of its competitors.

There’s a lot to like to about the Cateye Nano60, a rear light that lives up to its minimalist name. The light itself weighs a mere 20g (less than a packet of crisps) and even with the mount it’s a barely perceptible 30g.

Its small 30 x 32 x 30mm package still manages to pack in six modes and a reasonable 60-lumen output. But aside from its limited waterproofing and lateral visibility, this Cateye has few downsides.

Spec and modes

The Nano60 has the usual mix of solid and flashing modes. The two solid outputs are Low (3 lumens), and High (20 lumens). In addition to this you get Flashing (6 lumens), Group Ride (a pulsing 10 lumens), Daytime HyperFlash 1 (60 lumens) and Daytime HyperFlash 2 (20 lumens).

Battery life was good, even exceeding Cateye’s claims, though of course this can depend on other factors such as the weather; when it’s cold, battery life will be lower. I found that in the high mode it was still going strong after four hours – more than half an hour longer than Cateye’s claims.

Charging takes roughly 3.5 hours through its USB-C port. A USB-C cable isn’t included, but let’s face it, most of us have more than we need.

The performance in the various modes was decent, with both the Daytime settings visible hundreds of metres away even in bright daylight. The Group Mode does what its name suggests, slowly pulsing so it doesn’t blind your riding buddies sitting on your wheel.

Although Cateye says the Nano60 emits light laterally through the translucent sides of its back body, the side visibility is sparse compared to a lot of other lights that have cleat plastic sides.

In terms of features, the Nano60 has a low battery indicator, which will automatically switch to flash mode when the battery is running out. As with most modern lights, it turns on in the mode it was in when you switched it off.

The SP-14-RA aero seatpost bracket is impressive. It’s designed to fit seatposts from 21.5-32mm in diameter, and thanks to its strong and flexible elastic band, it will fit around D-shaped posts as well as round ones.

I found the light easy to remove from the bracket too. Replacement brackets are available for a fiver, and Cateye also sells adaptors that allow you to fit it to a saddle rail or seatstay.

The waterproofing is slightly disappointing for a rear light, its IPX4 rating showing its resistant to showers rather than being 100% waterproof like a lot of the Cateye’s competitors. It is still working after getting covered in rain and mud – and when it was accidentally left on the bike when I cleaned it – but I’d rather have had IPX6 or IPX7, which means it could survive being submerged in water.

Value

For £29.99, you can buy more powerful rear lights than the Cateye Nano60 – but its output is competitive for a light of such a low weight.

For example, the Knog Plus Rear Light that we tested a while back is cheaper at just £17 and is also a couple of grams lighter, but it only puts out 20 lumens.

The Giant Recon TL 200 is now £39.99, a fiver dearer than when we tested it – but it’s also more than three times as powerful and has a much higher waterproof rating. But while it is heavier, I’m not convinced you’d be able to detect the 16g weight difference.

Meanwhile, if you’re looking for a rear light with maximum visibility from the side, the £40.99 Moon Cerberus rear light is your new best friend.

Conclusion

The Cateye Nano60 is a decent little light with versatile mounting options and a very low weight, but I can’t help but feel unless you’re an absolute weight obsessive, there might be better options out there.

Verdict

Long-running and bright for its modest size and weight – but side visibility and waterproofing could better

road.cc test report

Make and model: Cateye Nano60 Rear Bike Light

Size tested: 60 lumens

Tell us what the light is for, and who it’s aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Cateye says: “The compact Nano60 is equipped with our latest OptiCube™ lens technology, providing daytime visibility. Small enough to forget it’s on your bike, but always there when you need it. The included SP-14-RA bracket is compatible with modern aero seatposts. Snap System™ compatibility allows the light to be attached to a wide variety of mounts, including our saddle rail and rear rack brackets.”

It’s a good little light, easy to use and virtually weightless. Though I’d have preferred greater weather resistance and more visibility from the side.

Rate the light for quality of construction:
 
7/10
Rate the light for design and ease of use. How simple was the light to use?
 
8/10

Very easy to use. It just has an on/off switch on top that also skips through the modes.

Rate the light for the design and usability of the clamping system/s
 
8/10

Keeps the light in place on round and aero seatposts. You can buy brackets separately and there are adaptors that allow you to fit it to a saddle or seatstay.

Rate the light for waterproofing. How did it stand up to the elements?
 
6/10

The waterproofing rating is lower than I’d like for a rear light that’s more likely than a front light to get covered in spray from the road and mud and muck if you’re riding off road.

Rate the light for battery life. How long did it last? How long did it take to recharge?
 
9/10

It ran for longer than Cateye claims in its highest setting and in its lower outputs it’ll be weeks before you need to recharge it. Recharging takes about three hours through the USB-C port.

Rate the light for performance:
 
7/10

Its battery life and brightness is good but its visibility from the side is disappointing for a rear light.

Rate the light for durability:
 
7/10

It’s well made and the durability should be good, though the moderate waterproofing could be problematic.

Rate the light for weight:
 
9/10

As far as I can tell, its lumen-to-weight ratio is about the best out there.

Rate the light for value:
 
5/10

The price is about right for a light with this output. There are cheaper, less powerful alternatives, though you can easily pay a lot more for more powerful rear lights.

Tell us how the light performed overall when used for its designed purpose

It has a decent output and it’s easy to use. And it’s very light and compact, of course.

Tell us what you particularly liked about the light

It’s light, very compact, bright and with good runtimes.

Tell us what you particularly disliked about the light

I’d like more visibility from the side and better weather resistance.

How does the price compare to that of similar products in the market, including ones recently tested on road.cc?

The price is about what you’d expect for a rear light of this brightness. That said, you can find highly rated cheaper rear lights, like the Knog Plus Rear Light, or you could easily pay more, for highly rated lights such as the Giant Recon TL 200.

Did you enjoy using the light? Yes – it was fine

Would you consider buying the light? No

Would you recommend the light to a friend? Maybe – if they wanted to maximise brightness and minimise weight.

Use this box to explain your overall score

The Nano60 is a good rear light. But there are more powerful lights out there that are only slightly more expensive than the Cateye, which would score more highly if it had better visibility from the side and more weather resistance. This is one if you’re looking to trim weight to the minimum while still having a decent output.

Overall rating: 7/10
