This battery-free LED bike light uses magnets as a power source

CIO Battery Free Bike Light by Reelight — Kickstarter
Reelight’s bike lights have been keeping cyclists safe for more than 10 years, but the team behind them is now aiming to score Kickstarter backing for an upgraded design.

If you’ve not heard of Reelight‘s frictionless light system, here’s a quick overview. It comprises two parts: the light, which attaches to the front or rear left fork of your bike, and a magnet, which attaches to a spoke. As the wheel turns, the magnet powers the light, which flashes as you ride and stays lit for up to two minutes if you come to a standstill, such as at a stop light.

The “always on” bike light flashes night and day when you’re riding, a factor that Reelight says significantly ups its safety credentials. In addition, its battery-free design means you’ll never have to worry about it suddenly dying on a ride home in the dark.

The all-new Cio light

Reelight, an award-winning bike-light firm based in Denmark, is planning to launch its latest design, the Cio, via Kickstarter. The upgraded version has been improved to offer greater light intensity for other road users and pedestrians — it can be seen up to 300 meters away — and includes decent side visibility for everyone around you.

According to Reelight, it takes just a few seconds to attach the light to your bike using a new patent-pending mounting system.

As for the magnet, Reelight has redesigned it to make it more powerful, and while the system used to consist of two 12-centimeter (4.7 inches) modules, it’s now just one small, coin-sized magnet.

Worried about someone nabbing your light? Reelight says, “Since the lights are being mounted with a key, it’s very difficult for a thief to steal it. The wire is made out of coated stainless steel and is very hard to break.”

The eight-person team is looking for about $40,000 in funding to start shipping the Cio in October 2017. Early bird backers can pre-order a set (one white and one red) for about $40, which is around 38 percent off the expected retail price.

The new design “is just the kind of bike light that every avid biker was waiting for as it has no batteries, no friction, and can be easily mounted,” Reelight said. It certainly looks pretty appealing, and with the company’s lights already fixed to one out of every three bikes in Denmark’s main cities and 10 million sales made worldwide, this latest design could soon be lighting the way for many more cyclists before too long.

There's a scene in Mission Impossible 3 that you might recall. In it, our hero Ethan Hunt (Tom Cruise) tackles the movie's villain, holds him at gunpoint, and forces him to read a bizarre series of sentences aloud.

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.
