Knog Cobber Reflex Lights Adjust Output Based on Speed, Lean Angle
Summary By: eMotoX
Knog has introduced an innovative update to its Cobber light series, incorporating Adaptive Reflex technology that adjusts light output based on ambient brightness, speed, and bike lean angle. These smart lights, designed primarily for traditional bicycles but compatible with e-bikes, offer an exceptionally wide 330º beam angle for enhanced visibility. The rear light notably features dynamic strobe effects that change according to the bike’s lean, effectively signalling turns, while both front and rear lights automatically brighten in darker conditions or at higher speeds.
The Cobber Reflex lights come with several practical features, including motion-activated on/off functionality, USB-C charging, and excellent side visibility to improve rider safety. The rear light also doubles as a brake light by brightening when deceleration is detected via an accelerometer. This light’s wide beam angle extends around the rider’s legs, creating a bio-motion effect that further increases visibility to drivers approaching from behind. Both lights are lightweight, waterproof, and equipped with quick-release mounts for easy installation and removal.
Users can customise the lighting modes through a dedicated web app, allowing them to save profiles tailored to different riding scenarios such as commuting or training. Alternatively, riders can choose from four standard modes with varying brightness and runtime options. The front light offers up to 150 lumens, while the rear light reaches 75 lumens on high settings, with runtimes ranging from 2.5 to 8 hours depending on the mode selected.
Priced at $79.99 each, the new Cobber Reflex lights maintain the same affordability as the original Cobber models, with a bundle option available for $149.99. This combination of smart technology, practical features, and competitive pricing positions Knog’s latest offering as a compelling choice for cyclists seeking enhanced safety and convenience on the road. The lights are currently available through Knog’s website.
