XParents of Child Killed in E-Bike Accident Sue Manufacturer, Signaling Future Challenges to Industry
Tragedy struck the Steinsapir family on January 31, 2021, when 12-year-old daughter Molly was gravely injured while riding as a passenger on a Rad Power RadRunner e-bike. The accident occurred in Pacific Palisades while Molly was riding on the bike's rear rack. She suffered a severe brain injury—the girl underwent multiple surgeries but passed away just two weeks later.
In early August, the LA Times reported that Molly’s attorney parents, Jonathan and Kaye Steinsapir, filed suit in a Los Angeles court against Seattle-based Rad Power Bikes, alleging negligence and product defects led to their daughter’s death.
The Steinsapirs’ suit comes as the micromobility industry continues a strong recovery from the lows of the COVID-19 pandemic. According to recent data from the U.S. Bureau of Transportation Statistics (BTS), the number of docked bikeshare systems has nearly doubled in the past five years, with over 100 such systems in operation nationwide. In addition, the number of individual docking stations has also grown, with 8,457 currently in use.
It’s also a highly visible recovery: Travel to one of several major cities like Austin, Los Angeles or New York, and you’ll eventually spot someone zipping down the street on one kind of electric ride or another.
Molly Steinsapir was a passenger on a privately-owned RadRunner e-bike when her 11-year-old friend, who was steering, lost control. The friend was only mildly injured in the accident, and her account of what happened led the Steinsapirs to believe that the product defects such as issues with the RadRunner braking system played a role. In addition to arguing that the e-bike was defective, the lawsuit also alleges that Molly's Giro Sport Design Inc. helmet was flawed.
Responding to dot.LA's request for comment, Rad Power Bikes said, “The entire Rad Power Bikes team extends its deepest condolences to the Steinsapir family on the tragic loss of Molly Steinsapir. We are aware of the lawsuit that the family has filed. Rad Power Bikes does not comment on pending litigation, including this case, and therefore has no comment on the allegations in their complaint or the underlying accident.”
The Steinsapir’s suit goes explicitly after the bike and helmet makers. But, in general, it adds a new layer of litigation onto an industry already facing legal challenges on multiple fronts—such as when the city of San Diego sued several scooter companies in 2021 to ensure the firms would meet their obligations if they lost in court. Or when Lime was hit with a class-action lawsuit in 2020 that alleged, among other things, that the company didn’t maintain its inventory, leading to accidents and injuries. Then there are the multiple web pages maintained by law firms with titles like “New York City Electric Scooter Accident Lawyer” and “E-Scooter Disability Lawsuit.”
Additionally, as Jonathan Steinsapir told the Times, “Rad Power Bikes has simply turned a blind eye to the fact that children under 16, under 18 are using their products all over the country.”
It’s true as the Times reported that the buyer’s manual for the RadRunner neglects to mention that the bike shouldn’t be operated by people under 18 until near the end of the 57-page document. Olivier Taillieu, the attorney who filed suit on the couples’ behalf, noted that e-bikes and scooters appeal to kids because “they take you places you wouldn’t normally be able to go, which includes uphill.”
Children can easily access motorized scooters and bikes even when companies appear to take precautions. Parents might have to use an ID to open an account to rent scooters from one of the nationwide services like Lime, but once that account is established, it’s a no-brainer for kids to simply use their parents’ credentials. Then children as young as 11 can access equipment capable of speeds up to 20mph on city streets. The American Academy of Pediatrics recognized the dangers three years ago when it recommended that no one under 16 operate e-scooters or electric bikes—the same year researchers called injuries from motorized scooter use “a rising epidemic.”
As accidents happen and lawsuits mount, the e-bike industry will likely have to confront the prospect of more regulatory scrutiny from cities where they’ve established firm footholds.

An LA AI Company Just Won Entertainment’s Backing
🔦 Spotlight
Hello LA.
The entertainment industry has spent the past several years debating what generative AI could take from creators.
This week, some of its biggest companies put money behind an AI startup promising to build something for them instead.
Los Angeles-based Stability AI raised $76M in Series B funding from an investor group that includes Electronic Arts, Sony Music Group, Universal Music Group and Warner Music Group. AMD Ventures and Pacific Alliance Ventures also joined the round, while LA-based MANTIS Capital and Sound Ventures are among the company’s existing backers.
The financing brings Stability AI’s total funding under CEO Prem Akkaraju to $232M, including two equity rounds and convertible notes. The company plans to use the new capital to expand its creative production tools, applied research and professional services across music, gaming and entertainment.
The amount is notable. The names attached to it are the bigger story.
Generative AI’s arrival in entertainment has been anything but quiet. Artists have questioned whether their work was used to train models without permission. Studios have faced pressure over how the technology could affect jobs. Record labels have pursued AI companies in court while simultaneously exploring how the same technology might fit into their businesses.
Now, several of the world’s largest entertainment companies are investing directly in one.
That does not mean the industry has resolved its concerns about AI. It means some of its biggest players would rather help shape the technology than wait to see what it becomes.
Stability AI is positioning itself for that opening. Rather than focusing solely on general-purpose models, the company is building tools specifically for professional creatives. Its recently launched Stable Audio 3.0 was trained on fully licensed music and lets artists generate, edit and arrange audio through a web platform or directly inside digital audio workstations.

That licensed-data approach is central to the pitch. The next phase of creative AI will not be decided only by which company produces the most impressive model. It will also depend on which companies can earn the trust of the artists, studios and rights holders whose work gives those models value.
For its new strategic investors, the round offers more than financial upside. It creates a closer view into how generative AI may change production, a voice in how the tools develop and an opportunity to establish rules before those rules are established for them.
For Stability AI, the backing provides something equally important: credibility inside industries that have every reason to scrutinize what it is building.
The company now has capital and access to some of the largest catalogs, franchises and creative workforces in entertainment. What it does with that access will determine whether this becomes a meaningful alliance or simply an impressive collection of logos.
Either way, the industry is no longer watching from a safe distance.
It has entered the room.
LA’s Air-Taxi Plans Are Coming Downtown
While Stability AI is trying to change how entertainment gets made, Archer Aviation wants to change how people get to it.
AEG and Archer announced plans to develop downtown Los Angeles’ first vertiport at L.A. LIVE, creating a potential new stop in Archer’s proposed electric air-taxi network ahead of the 2028 Olympic and Paralympic Games.

The planned site would sit beside Crypto.com Arena and allow passengers to travel to and from the entertainment district aboard Archer’s Midnight aircraft. The company says its network could turn drives that take an hour or longer into electric flights lasting approximately 10 to 20 minutes.
Archer has already identified SoFi Stadium, USC and Hollywood Burbank Airport as possible locations, with its recently acquired Hawthorne Airport expected to serve as the network’s central operating hub. As the official air-taxi provider of LA28 and Team USA, Archer has an unusually visible deadline for turning those plans into something tangible.
AEG and Archer have completed an initial feasibility study of the L.A. LIVE site, including reviews of land use, airspace, power availability and community impact. The next phase will examine operations and the passenger experience.
There is still a substantial distance between a proposed vertiport and a functioning air-taxi network. The infrastructure must be built, regulatory approvals must be secured and passengers must be persuaded that flying across the city is safer and more practical than staying on the ground.
Still, few locations could make that future feel more real than L.A. LIVE. Millions of people already pass through the district for concerts, games and major events. Placing a vertiport there would bring urban air mobility out of the concept stage and directly into public view.
Together, this week’s announcements show Los Angeles becoming a testing ground for two technologies still moving from promise toward everyday use.
One could reshape how entertainment is created. The other could reshape how Angelenos reach it.
In a city famous for both its creative industries and its traffic, that feels appropriately on brand.

Sandbox Studios’ Jackie Fast on the New Ways Celebrities Are Partnering With Startups
Jackie Fast doesn’t think celebrities make good entrepreneurs. Instead, they make great assets for young companies.
On this episode of the LA Venture podcast, the Sandbox Studios managing partner discusses why many celebrities are exploring startups. Sandbox is a $30 million seed-stage fund that invests in brands that are being built by celebrities.
“The motivation for me is absolutely everything,” Fast said. “Why is this person doing this? Often—I mean, 100 times out of 100—it's not because they care. They want to make more money.”
Fast started her consultancy, Slingshot Sponsorships, at 24, after she was passed over for a role at the organization at which she was working.
“I was very qualified for the role. Even to this day, I still am annoyed about it. I applied and the CEO just said, ‘You're too young. You need more experience’.” She quit soon afterward and by 26, Fast signed Prince as her second client—without realizing that the iconic musician was notoriously uninterested in sponsorships.
“Prince was one of my first clients and—I didn't know this at the time—but the reason we got Prince was because nobody wanted to work with him to do commercial stuff. Because he didn't care. He's all about the music.”
Fast helped launch his album “20Ten” through Spotify and the DailyMail. It was the first time an album had launched on the growing music platform, and the move helped Prince quickly climb the charts.
“That just catapulted me into the music scene,” Fast said.
She took on clients including The Rolling Stones, Duran Duran and One Direction.
“My whole ethos was that social media and digital technology was changing and shaping the way that consumers and fans could engage with the things that they loved,” Fast said.
Slingshot prepared Fast to evaluate celebrity-backed companies and consider how their audiences can help a product thrive.
“A brand fundamentally is trying to ship product. So there are certain times when consumers are more receptive to information. And a lot of that is when they are enjoying themselves, they're having fun, they're in a calm place,” she said. “So any of those kind-of core emotional, humanistic things that connect people with other people—if a brand can insert themselves in the middle of that—that's where the recall comes from. That's where you start associating your own individuality with a brand.”
Celebrities began eyeing equity deals more seriously after George Clooney sold his tequila company, Casamigos, for $1 billion in 2017. Instead of promoting the brand for cash as most celebrities do, Clooney—one of its founders—opted for equity. When the brand eventually sold, he did well.
“When George basically did nothing and made a billion dollars, everybody was like, ‘Oh my goodness, we should be doing this. Why are we taking fees?,” Fast said.
The problem, she added, is that most talent agents make their money through commission and wouldn’t benefit from equity deals. Many of them ignored celebrities’ requests, leading frustrated talent to reach out to startups on their own—sometimes even using DMs to initiate contact. Often the resulting deals were not good ones, Fast said. Large talent agencies including CAA and WME have since set up venture arms for their clients.
Sandbox’s portfolio includes Kylie Cosmetics, Fabletics and Aviation Gin. The fund also invested in the animation studio Invisible Universe, alongside partners including Reddit co-founder and investor Alexis Ohanian. Invisible Universe partners with celebrities to create animated characters and build their following on social media. Once they gain traction, they can become the basis for books, shows, podcasts and other creative ventures.
“With these small animation companies, they can turn around ideas in a day and a half,” Fast said. “They create short form content that goes on Instagram Stories, TikTok [and] Reels, and they build momentum and following through lots of short-form content.”
While Fast invests in products built by celebrities, she said she views them less as entrepreneurs and more as a way for companies to gain instant brand recognition.
“I'm investing in a route-to-market and an asset that most companies don't have access to,” she said. “I don't look at the celebrity as like a person or a founder. I look at the celebrity as the marketing arm or the marketing special dust that you can add to a product.”
