At road.cc 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.What the road.cc scores mean

The NiteRider Lumina Micro 900 Bike Headlight is a sturdy, no-frills model that, as the entry-level option in the Lumina range, delivers good performance for the price. It's great to use, definitely made me feel safe and visible, and aside from a slightly overactive lock mode, is easy to figure out. However, it is fundamentally let down by a flawed mounting lock which left me collecting it from the floor on multiple occasions.
While I did enjoy using the NiteRider, there are a few areas where I feel it could be improved: it has a strong 900-lumen capacity, but there isn't a huge amount of side-on visibility, and there's only the one flashing mode. The lack of a quick-charging USB-C port and the two-hour run-time on full beam means the Micro 900 is probably best suited to shorter rides.
Check out our guide to the best front bike lights for more options.
My personal preference is for lights to do the simple things well, without complex mode and button combinations that, to my mind, are just unnecessary bells and whistles, but you might find the five choices of solid 30/200/450/900 lumens and flashing 900 somewhat limiting.
At the minute, I'm mainly riding around London at peak times, so I mostly used the flashing 900 setting. I try to keep it lowered so as not to dazzle oncoming cyclists, but there are more advanced lights available, like the Ravemen mentioned below, with that kind of functionality. There's also limited side visibility.
When I did need full glow on quieter, less urban roads, I was happy with the beam's road coverage. It has a strong, white, forward-facing beam and I could easily pinpoint potholes when careering along country lanes at speeds over 35kmph and felt safe using the light's one-button system on the move.
On the full 900 lumens you get just under 2 hours of life, with flashing 900 a claimed 11 hours. While 4.5 hours on 450 lumens is decent, combined with the fact that you can't charge and use it simultaneously, bikepackers and endurance riders will probably look elsewhere.
The light and mount weighed 160g on the road.cc Scales of Truth, which is competitive for lights of this spec. The mount doesn't require any tools and is versatile, screwing onto my vintage Reynolds bike's handlebar as well as my modern aero bars.
As is quite common, a small rubber mount slots inside the mount to create a tight and grippy fit. This can fall out, so be very careful not to drop it on a dark pavement at night.
The light slides into the mount nicely but doesn't lock automatically – which I thought was a bit of an odd feature; you have to lift the 'handle' to activate the lock. And once locked, the connection seemed quite fragile and didn't inspire confidence.
Out on the road, this did cause some problems. If I forgot to click up the 'handle', the light would almost instantly detach and fall down through my spokes to the floor. I accept that this was mostly my fault, but even when I had remembered to click up the 'handle', on a number of occasions the light was dislodged at high speed. The light is now pretty bashed but does still work – so at the very least it proves its hardiness! I found myself holding onto it on quicker, bumpier descents, having lost confidence in the mount's ability to keep it in place.
Talking of locking... the light arrived in something called Travel Lock Out Mode, to avoid burning the battery in transit. It has a habit of flicking back into this mode – so you might find yourself digging through the instructions while thinking you've got a dud light. (You'll need to hold down the power button for 10 seconds to release it.)
Niterider is proud of its Intellicharge feature, which pumps through quicker power transfer when you use a higher-wattage power source. Perhaps I don't have fancy enough plugs, but I was never able to activate this double-quick charging.
It's a shame, because NiteRider has opted for the slower USB over USB-C, which seems slightly outdated. It's also not possible to charge and use the light concurrently.
The Lumina isn't waterproof, just water resistant to IP64, but it got a few decent drenchings without any issues. Elements of the electrics come with a two-year warranty, while the rechargeable battery cells get just a year.
For £60 the Niterider Lumina 900 is certainly competitively priced. A max output of 900 lumens is good – there aren't many in this price range putting out this kind of power. It's also well made and from a reputable brand so it strikes me as decent value.
The Exposure Boost Daybright, for example, was well reviewed by Ed, but despite an excellent build quality, it doesn't have the night-time capability of the Lumina and is mainly a 'be seen' light. It has a max brightness of 350 lumens and now costs £80.
With the NiteRider you get another 100 lumens over Lezyne's Micro Drive 800+ for the same money, though that has USB-C charging and a higher waterproof rating.
For another £20, the Ravemen PR1000 offers a bit more in terms of light variety and features than the NiteRider, and Stef liked the remote control button and was impressed by the battery life, though it's another one with a disappointing rubber strap.
The Lumina Micro 900 is a solid and sturdily constructed light, with a chunky mount that looks superior to the rubber straps used by some rivals, but couldn't be relied on. The light is also slightly let down by its strictly manual locking system, and some might be left wanting more beam options, but the battery life is decent and it won't be stopped by bad weather.
Limited beam options but does the basics well, though the mount needs revising

It's well made and fits neatly into the palm of the hand while being very sturdy. Keep an eye on the removable rubber mount insert – if you lose that you're in trouble.
There being only one button does simplify things, but the sequencing takes a while to master. The light lock-in system on the mount feels slight on first inspection and proved so during testing, dislodging on quicker and bumpier sections of rides.
A sturdy, plastic and quite bulky affair that won't perform well in the wind tunnel. The large hinge means it can fit on a wide range of handlebars including both my flat aero bars and my ordinary town bike. It screws on very securely and the light slots onto the clamp, but the lock system isn't automatic nor is it secure. Keep an eye on the removable rubber mount insert, too.
IP64 rated so not actually waterproof, but in all the soakings I gave it, no problems at all.
Not sure why NiteRider has opted for the slower USB over USB-C as that seems slightly outdated. It's not possible to charge and use concurrently. The battery life held up well to the stated times. If you can get the Intelli charge feature to work that would be a bonus.
No complaints at all. Simple but effective. All the run times are competitive with other lights and the single flashing option was enough for my needs. The light weight is also a plus.
Feels really strong and has taken a few tumbles (!) without any issues.
Competitive compared with similar output lights.
Tell us how the light performed overall when used for its designed purpose
It's the smallest and least bright of the Niterider Lumina range and I thought it packed a very decent punch considering. For road riding at night, in rural areas, it will have you covered for a couple of hours. I predominantly used the flash setting for city riding, so 11 hours of run-time per charge was good.
Tell us what you particularly liked about the light
No tool is required for the mount and it screws into place incredibly tightly. The light is very quick to remove – so it works well for commuting and when you're locking up and popping into shops. Minimal beam options are also a plus for me – spurious additional choices just waste time in my opinion.
Tell us what you particularly disliked about the light
The mount not holding the light securely at all times.
Puts itself back into 'Travel Lock Out Mode' frequently (so you'll need to hold down the button for 10 seconds).
It also says it has 'convenient on-the-go charging' and yet it can't be used while charging.
How does the price compare to that of similar products in the market, including ones recently tested on road.cc?
It's pretty competitive considering the spec.
Did you enjoy using the light? Yes
Would you consider buying the light? Yes
Would you recommend the light to a friend? Yes
Use this box to explain your overall score
It's a simple but strong light that covers the main bases without being wildly versatile, but the mount needs to hold it more securely.
