The US federal government’s consumer watchdog has issued a recall for “about 24,000” batteries sold with cheap VIVI e-bikes at retailers like Walmart, Amazon, and AliExpress for prices between $365 and $950. At least 14 incidents of overheating batteries have been reported, with three reported fires. No injuries have been reported, but owners are urged to stop using the e-bikes immediately because the lithium-ion batteries pose a “risk of serious injury or death.”

24,000 e-bike batteries recalled because the US can’t get its shit together

The VIVI e-bikes and batteries in question — models listed here — were likely not certified to UL safety standards. That’s not stated in the US Consumer Product Safety Commission (CPSC) recall notice, but it’s a near universal truth for budget brands selling e-bikes at rock-bottom prices. Certification costs money and is entirely voluntary outside of New York City. VIVI also seems to have started appending a “UL” to the end of its UL-certified model names.
Owners affected by the recall can contact VIVI to receive a free replacement charger and battery, though it’s unclear if the new battery will be UL certified. The recalled batteries were sold with e-bikes between December 2020 and November 2023.
Certification costs money and is entirely voluntary
The recall deals yet another blow to the reputation of electric bikes in the US, where a preponderance of e-bike incidents occur despite their minuscule share of the global market. In the EU, e-bikes are viewed as safe, reliable, healthy, and space-saving alternatives to automobiles and public transportation thanks largely to strict regulations. The VIVI recall is unlikely to be the last while federal lawmakers in the US continue to ignore e-bike safety.
VIVI’s e-bikes are made in China, like 86.3 percent of the US bike market. Prior to May 2nd, Chinese imports were eligible for the de minimis exemption, whereby goods costing less than $800 entered the country duty-free. The impact of this on the price of gadgets from Temu and clothing from Shein has been well documented, but that seemingly inconsequential exception also impacted e-bike safety.
First, it allowed those big lithium-ion batteries attached to cheap e-bike motors to be imported with minimal government inspection, as Consumer Reports warned back in 2022. It also incentivized e-bike makers to cut corners in order to beat that $800 cap. UL testing and certification has a one-time cost of between $30,000 to $100,000 per model, allowing companies like VIVI to undercut brands like Rad Power that willingly pay for the marketing that comes with a UL seal of approval.
There are two main safety standards that apply to e-bikes in the US: UL 2849, which applies to e-bikes, and UL 2271 for e-bike batteries. Both certifications are recommended by the CPSC but remain voluntary everywhere but New York City, which made them mandatory in 2023. As of September 30th, 2024, there were three deaths and 84 injuries from e-bike fires in the city, down from 14 deaths and 114 injuries for the same period a year earlier.
Statewide e-bike safety laws like the one coming into effect for California on January 1st, 2026 could convince more e-bike makers to seek UL certification. But only a federal mandate can guarantee a uniform approach and solve the battery safety issue once and for all.
In the meantime, we can expect more e-bike battery-related injuries to persons and property in the US. And since President Donald Trump is openly hostile to regulation and any form of transportation that doesn’t require exploding dinosaur juice, there’s little hope we’ll see a federal e-bike safety standard during his reign.
So, the best you can do for now is look for that “UL Certified” sticker. If you’re buying a new e-bike in the US, you should demand it. And if you already own a cheap Chinese import without it, well… maybe park it outside.

The LeapMove is a gamified camera designed to get kids off the couch

LeapFrog has announced a new electronic learning system that swaps controllers for a camera. In fact, the LeapMove looks like an oversized, kid-friendly webcam, but is designed to connect to TVs like a console and get kids off the couch using educational games that require full-body movements to play. It’s reminiscent of the Xbox Kinect or the PlayStation 2’s EyeToy, but simpler and much cheaper than competitors’ products like the $249 Nex Playground.
The LeapMove will be available through retailers including Target, Walmart, and Amazon for $69.99, and comes with 25 motion-based games designed for kids aged 4 to 7. It might be hard to pull the older end of that demographic away from games like Roblox, Among Us, and even Fortnite, but in addition to motion detection, the LeapMove uses its camera to make players appear as themselves or “whimsical characters” in several games, which may appeal to younger kids.
The games cover “foundational school subjects” including math, reading, and spelling, and require players to do everything from dancing around to waving their arms and even attempting to catch on-screen objects. The LeapMove connects to a TV over HDMI, and instead of rechargeable batteries it needs access to a power outlet. It can be used either sitting beneath a TV or perched atop it like a webcam using a fold-out support.
LeapFrog says additional games will be made available for the LeapMove at a later date, which can be loaded by connecting the device to a computer and using the company’s LeapFrog Connect desktop app. They won’t be free, but unlike the Nex Playground, the LeapMove doesn’t come with any subscription fees.
Parents concerned about privacy, particularly with devices that rely heavily on a camera, may appreciate that the LeapMove has no wireless connectivity. In 2018, VTech, LeapFrog’s parent company, agreed to settle for a $650,000 fine after the FTC alleged it collected kids’ personal information, including names, emails, and genders, through its KidiConnect mobile app. The LeapMove is completely standalone and keeps track of up to three players’ progress locally.

Meta is playing the AI game with house money

Mark Zuckerberg’s AI hiring spree is costing a lot of money. His investors don’t care.
Meta’s stock price shot up over 10 percent on Wednesday after the company reported better-than-expected earnings. Revenue generated in the second quarter was $47.5 billion, up 22 percent from a year ago. Daily users across Facebook, Instagram, Threads, and WhatsApp grew to almost 3.5 billion. Meta also warned Wall Street that it would spend more on data centers and hiring next year. In response to all this, the company’s valuation increased by over $175 billion, or more than 12 Scale AI deals.
”Our business continues to perform very well, which enables us to invest heavily in our AI efforts,” Zuckerberg said during today’s earnings call. Meta’s cash cannon is now fully pointed at his new moonshot of achieving superintelligence, or as he puts it, AI that “surpasses human intelligence in every way.” He bragged about providing the richly compensated members of his new superintelligence lab “access to unparalleled compute” for training new models that will “push the next frontier in a year or so.”
Zuckerberg’s last moonshot was the metaverse, which came up only once at the very end of today’s earnings call. It’s too early to compare the two projects, but they share a key similarity: they need the kind of funding that only a company like Meta can provide.
Where AI differs from the metaverse, however, is that it appears to be already improving Meta’s ads business. A new AI model for delivering ads has driven approximately five percent more conversions on Facebook and three percent more conversions on Instagram, according to CFO Susan Li. Large language models are also starting to power how posts are ranked in feeds across the company’s apps, including Threads.
While Meta is still spending heavily on the metaverse (it’s on track to spend a total of $100 billion on its Reality Labs division this year), there’s no mistaking the fact that AI is officially Zuckerberg’s top priority. This time, though, he’s playing catch-up in a heated race, not trying to invent a new platform from scratch. The stakes are much higher, even if he’s playing the game with house money.

YouTube tells creators they can drop more F-bombs

YouTube videos with strong profanity in the first seven seconds (words like “fuck”) are now eligible for full monetization, according to a video from Conor Kavanagh, YouTube’s head of monetization policy experience. Previously, these kinds of videos were only eligible for “limited ad revenue.”
Changes to YouTube’s inappropriate language policies have long been a sore spot for creators. In November 2022, the company began to potentially limit ad revenue if profanity was used in the first 8–15 seconds of a video. ProZD, whose real name is SungWon Cho, published a video where, after waiting 15 seconds, he called the policy change “the dumbest fucking shit I’ve ever heard.” (He later said that the video was demonetized.) YouTube adjusted its policies in March 2023, including allowing videos with profanity in the first 8–15 seconds to be eligible for ad revenue.
I asked ProZD his thoughts about Tuesday’s change. “It’s about fucking time.”
The company originally restricted monetization for videos with swearing at the start of videos to “align with broadcast standards,” Kavanagh says. “Advertisers expected ads on YouTube to have distance between profanity and the ad that just served.” However, “those expectations have changed,” he says, “and advertisers already have the ability to target content to their desired level of profanity.”
While the only specific example of “strong” profanity Kavanagh provides is “fuck” — he says that YouTube defines “moderate profanity” as words like “asshole” or “bitch” — “you get the idea,” he says.
YouTube will continue to limit monetization if you use moderate or strong profanity in titles or thumbnails. Videos with a “high frequency” of strong profanity are also still a “violation” of YouTube’s advertiser-friendly content guidelines, Kavanagh says. “You have to pick and choose your fucks carefully.”
