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
Good scores are more common than bad, because fortunately good products are more common than bad.
The Lezyne KTV Drive Pro+ LED Rear Light is fine. It gets the job done, feels very much like it will last and the price is fair. It doesn't do anything particularly badly. The problem is, there's plenty of competition that does it all a little better. You can check them out in our guide to the best rear bike lights.
Instead of a port for the usual charging cable, this has a male USB spade that plugs directly into a computer or wallplug socket. It's hidden under the large rubber bung beneath the lens.
This works just fine in the sense that it's very well sealed – the waterproof rating is IPX7, which means it can sit in a metre of water for 30 minutes – and no amount of normal-riding shock is going to make it fall off, assuming you've pushed it fully home in the first place. In fact, I've been running a Strip Drive 150 for years with this same design, and the USB contacts are still clean and bright. Wear from the rubbing of constant capping/uncapping is minimal.
There are issues, though. As the cap is completely separate it's possible to lose it while you're charging; do that and your light is very vulnerable. A small tethered bung over a socket, as most lights have, doesn't suffer that problem.
It's also very important not to get ANY dirt inside the rubber bung; it's a tight fit and even tiny particles will start scratching the electrical contacts each time you install or remove it. Plugging a wet, muddy unit directly into a plug or computer is a lot less convenient than being able to use a long lead, too.
Also, even though the spade on the KTV is several millimetres longer than on my older unit, it's still not long enough to work in every socket. The very first charging plug I tried, in fact, wouldn't work. Even a slight recess to the socket can make getting a connection impossible. Again, the little USB-C ports we typically see don't have this problem.
The final issue is that the lens can't cover the unit's entire height because the bottom section is the bung, and that – coupled with decent if not outstanding side coverage – is a shame when others are making lights that are more lens than case. The Cateye Viz 150, for instance, is almost entirely translucent, and it's actually slightly cheaper at £29.99.
Still, on price the KTV is competitive, and very close to a host of similar lights – though many aren't as powerful.
The Magicshine Seemee 100 is only two-thirds as bright, for instance, and is also £29.99, though it does pack in a braking mode too. The BBB SignalBrake Auto Brake offers a (you'll never guess) brake function, but maxes out at 50 lumens and is £36.99.
Then again, the Gaciron Loop 100 Smart Brake Light also isn't as bright but still manages 100 lumens, has that clever brake light function too, and is nearly £10 cheaper at £22.64.
There's no brake light mode on the KTV, but not everybody is a fan of those anyway – they make battery life hard to judge and don't always work that reliably – and the six modes you do get are well chosen. It features two solid modes, two flashing ones, an always-lit pulsing one and a dim (5 lumen) backup that lasts up to 20hrs.
Only the Day Flash uses the full 150 lumens, and it's bright; the regular Flash 1 is just 25 lumens. It's a shame it's not 50 lumens as the Blast and Pulse modes are, and you can't blame the relatively small battery (400mAh) for that decision. Okay, the 25-lumen flash ekes out an impressive 18hrs (claimed and accurate) from the battery, but that 400mAh cell still manages 10.5hrs on the 150-lumen flash. A 50 or even 75-lumen flash would still give very usable run times.
That small battery means charging is usefully fast, at 2hrs 10mins from flat via a 2A USB wall plug.
If you're wondering why I haven't mentioned the mount yet, it's because that's also perfectly okay. It could be better – making one end captive would remove the risk of losing this part as well – but it's easy to attach and perfectly secure once on.
Overall, the Lezyne KTV Drive Pro+ is pretty effective and easy to use, and the price is decent. A fair few aspects of the design, however, just feel a bit more compromised than you might expect in 2024; there are neater creations out there you could go for instead.
Compact and potentially very bright, but mostly pretty average – and this design is starting to feel old

Would you consider buying the light? Yes, but then I'd choose something else.
Would you recommend the light to a friend? Not especially.
Use this box to explain your overall score
This is bright, pretty effective and pretty easy to use, but the design feels a little clunky and outdated against much of the competition. Really it needs more lens and fewer separate pieces to match today's slicker designs. Overall, it's 'quite good' and a 6.
