Cybersight was showing off their Zenith biking glasses at CES 2026, and it came with the usual buzzwords. What SemiAccurate found interesting is what they didn’t do rather than what they did do.
Non-regulars at SemiAccurate might not know it but I am a big biker, mainly because I enjoy it. I don’t use all the latest gadgets, gear, and shiny bits because most of them are worthless. I just have a good bike and mount my phone on the handlebars. The only other electronics I use is my watch, a Garmin Fenix 6 which is some of the best hardware I have ever used coupled to abysmally awful software, bad enough to have prevented me from upgrading for years. In any case I don’t buy the latest shiny bits, just what I need. Why am I saying this in an article about Cybersight and their Zenith glasses?
The Zenith glasses and accessories
That is pretty easy to explain, they are minimalist devices. Monochrome display, data fields only, and their big promotional point was light weight. For some bikers, weight is the big issue, and the same goes for VR/AR/HMDs, every gram can become an issue after a long ride or hours of use. The thing that attracted me to the Zenith glasses was that they were light, 39g claimed, and did only what you need them to do, essentially be a HUD. Basic data is displayed in monochrome, big numbers and letters, and it is fairly adjustable.

The fields you can see on the phone above can be moved around with a drag, and you can add on or take off fields you don’t care about. It is minimalist and that is a good thing. Cybersight touts an AI analysis feature but, well, find me anything at CES of late that doesn’t have AI something. Officially these AI agents are for coaching, biometric alerts, and the like but if history is any example they get turned off after the first use.
That brings me to the point of how well the Zenith glasses work. I had minimal time with them at Showstoppers before CES 2026 but they did seem to work well. They were compatible with my normal glasses, something many VR/AR devices fail at, were light enough to not be annoying. The data displayed was clear and large, adjustable for size, and could be positioned easily on the app. There is also a remote the clips onto our handlebars to turn things on and off, handy for busy areas.
Zenith lacks some things that most others tout. It has a full color depth of 1-bit, green, and that is perfect. More sucks battery and compensating adds weight. It doesn’t have speakers which aren’t needed for this type of work anyway. It doesn’t do text messages, have a paperclip avatar, or any other cutesy frivolity, just the basics and from what I have seen, does them pretty well.
Note: Temp is in F, wind is in MPH, and rain does not fall at those temps, snow does
Battery life is a claimed 8 hours, good enough for most rides, the lenses available are UV filtering, and it is IP54 rated. Basically Zenith does what it should and nothing more. About the only quibble we have with the glasses are the operating temp range, -10C to +55C, the top not being the issue but the bottom… look at the pic above from one of my recent rides, a humanitarian mission to Costco to get a hotdog for lunch. That ~1C delta would probably have been OK but why risk it?
If you want a Zenith, they are on sale now for $399 as of this writing. To some these glasses are feature free but to anyone serious about biking, they do what they need and no more. That avoids the weight, size, and cost death spiral of feature creep, something that rarely adds any useful functionality. Without a full review we won’t recommend them outright, but will say they are worth consideration based on the time we had with them. If only more companies understood what Cybersight does, the world might be a better place.S|A
