Knog has been around for ages, but it seems like lately they’re really coming back strong. Knog’s latest lights add Adaptive Reflex technology to their already impressive Cobber series (which were launched back in 2017), which delivers an exceptionally wide 330º beam angle. Knog is calling them “smart lights for analog bikes,” though you could totally run these on your ebike, too.
Now, they automatically dim or brighten based on how bright it is out, how fast you’re going, and how far you’re leaning your bike. That latter one? It’s mostly for the rear, changing the strobe effect to animate a right or left turn, acting like a quasi-turn signal.
Otherwise, the lights get brighter as you speed up or head into a dark tunnel (or, you know, you ride at night). You can customize the modes via their web app (and save the profiles like ‘commuting’, ‘training’, etc.) or just rely on the four standard modes. Output varies by model, and here are your options:
| FRONT | REAR | |||
| MODE | LUMENS | RUNTIME | LUMENS | RUNTIME |
| High | 150 | 2.5 hr | 75 | 2.5 hr |
| Low | 50 | 8 hr | 20 | 8 hr |
| Hype | 350 | 8 hr | 250 | 8 hr |
| Eco | 40 | 40 hr | 20 | 70 hr |
Both lights feature automatic (motion-based) on/off, USB-C charging, and excellent side visibility. And while the front is brighter, the rear is the workhorse with a couple of extra benefits.
First, it has the aforementioned lateral effects when you lean into a turn. More practically, an accelerometer senses when you slow down and brightens to act like a brake light.
And because the light spreads so far around to the sides, it illuminates the backside of your legs, adding a bio-motion effect that makes you stand out even more to drivers coming up from behind.
Both are lightweight, waterproof, and come with quick-release mounts.
Maybe the best part is the MSRP is $79.99 per light, which is the same price as the original Cobber. Or, they’re available in a bundle for a bit less at $149.99. Available now.
