When you’re done riding the S1 ebike, fold it up and pop it in your backpack

Add as a preferred source on Google

Claiming to be the world’s most compact and lightweight ebike, the Smacircle S1 sports one of the most striking designs we have ever seen for such a machine. That’s not something we say lightly, either, given the overwhelming abundance of electric bikes and vehicles on the showroom floor of CES.

Looking from some angles like an elaborately designed pair of (very large) spectacles, the ebike’s strong carbon fiber frame tips the scales at just over 15 pounds and can handle anyone weighing up to 220 pounds. Handily, the S1 folds up into such a tight package — and does so in a mere 10 seconds, apparently — that you can drop it in a backpack once you reach your destination, or carry it directly into your home or office.

To create an ebike that was able to transition from a compact, backpack-friendly design to a fully functional ride was what Smarcicle founder and CEO Shanggui Wu set out to do when he began developing the device. Bikes like the Smacircle S1 are often popular with folks with short commutes between a station and the workplace, and the S1’s top speed of 12.4 miles per hour will likely to save you a decent amount of time than if you were to walk the same route.

Of course, one of the burning questions for any potential ebike buyer is: “How long can I ride it for?” The S1 promises a one-hour ride at top speed, and twice that at 6 mph. The bike’s lithium-ion battery, tucked away in the seat, takes about 2.5 hours to fully recharge. Run out of juice mid-ride and you’ll have to carry it or shove it in your bag, however, as there’s no manual ride option. That said, you will still be able to coast down any slope you might happen to be upon when the battery dies.

An accompanying mobile app for iOS and Android lets you monitor battery usage and speed via your smartphone, which you can slot in the center of the handlebars. Speed is controlled either via the app or a built-in throttle, and other features include electronic brakes and built-in lights for night riders.

Shenzhen, China-based Smacircle smashed through its $30,000 funding goal on Indiegogo over the summer, and is gearing up for a mid or late-February release following the Chinese New Year. If you back the project to the tune of $778, you’ll also receive a spare battery and a dedicated S1 backpack, which seems like a steal when you consider that the ebike is expected to retail for $1,500 when it launches in the United States. Either way, it’s certainly cheaper than our favorite ebikes.

Google has been finding more ways to make Gemini a part of your daily routine, from putting together playlists to ordering groceries through your favorite apps. Now it's expanding those capabilities to more services, with Google Search joining in, too.

The company has announced a new Connected Apps Platform that makes it easier for developers to bring their services to both Gemini and Search. Alongside this, Google is adding new partners to its growing lineup, bringing more of the apps people already use into its AI ecosystem.

AI bots are now trying to sabotage public health policies, like banning disposable vapes
Thousands of AI bots voted in a public health poll to block sales restriction on disposable vapes. It's like Big Tobacco is back from the dead.

In the broad context of AI and its perceived harms, health and medical risks often pop up in the conversation. The warnings even come from frontier AI labs, such as ChatGPT-maker OpenAI and Anthropic, both of which have warned about misusing AI to cook up bioweapons. Security experts have already spotted a few such incidents in the wild, especially with the usage of AI models without any solid guardrails. 

Well, it appears that the risks run deeper. As per an analysis appearing in the British Medical Journal (BMJ), AI bots are now being deployed to influence public policies governing health risks to citizens. In this instance, an attempt was made using AI bots to thwart regulations that aim to restrict the sale of disposable vapes, all while disguising the manipulation efforts as a response from real humans.

A tiny smartphone gadget can detect some of the nastiest chemicals in your water
Scientists built a tiny smartphone gadget that can spot toxic 'forever chemicals'
Smartphone-connected drinking water safety sensor Featured

What if checking your drinking water for dangerous chemicals were as simple as plugging a tiny gadget into your smartphone? Researchers in Japan have developed a compact sensor that could make that possible, potentially bringing sophisticated water contamination testing out of expensive laboratories and into people's hands.

Scientists at the Okinawa Institute of Science and Technology (OIST) have created a portable device capable of detecting extremely low concentrations of PFAS, commonly known as "forever chemicals." The findings were published in the journal Biosensors and Bioelectronics, which demonstrate how an inexpensive sensor and a smartphone could make identifying potentially harmful chemicals in water a lot easier.
