24,000 E-Bike Batteries Recalled Over Fire Risk—UL Certification Debated
In a startling development raising alarm across the burgeoning electric bicycle market, the U.S. Consumer Product Safety Commission (CPSC) announced a major recall: approximately 24,000 lithium-ion batteries sold with VIVI e-bikes have been pulled due to fire and burn hazards. While no injuries have been reported, the batteries have been linked to 14 overheating incidents, including three confirmed fires.
A National Safety Wake-Up Call
This recall highlights a growing concern: in much of the U.S., UL certification—specifically UL 2849 for e‑bikes and UL 2271 for e‑bike batteries—is voluntary except in New York City, which made it mandatory in 2023. Many low-cost overseas brands, including VIVI, intentionally bypass certification to stay under the $800 “de minimis” import threshold, avoiding customs duty—and, problematically, safety oversight.
Experts warn that without federal-level regulation, safety remains at the mercy of cost-cutting measures. While states like California plan to mandate safety standards by 2026, only a unified federal mandate can ensure a consistent, effective solution.
What U.S. Consumers Need to Know
- If you or someone you know owns a VIVI e‑bike purchased between December 2020 and November 2023, you should immediately stop using it and contact VIVI for a free replacement battery and charger.
- Dispose of the recalled battery safely at a household hazardous waste (HHW) collection center, and confirm disposal—VIVI requires this to be emailed back.
- Checking for the “UL Certified” label on e‑bikes and batteries should be a normal part of the shopping process—right now, it's one of the few lines of defense for American consumers.
The Other Side: A Safer Alternative for Students and Commuters
In the wake of the recall, thoughtful shoppers—especially students preparing for the new academic year—are seeking safer, UL‑certified e‑bike options. One brand making waves in this space is DYU.
On DYU’s U.S. site, the Back‑to‑School Sale is in full swing, offering up to 50% off on select models. Among these, three standout e‑bike models offer safe, stylish, and affordable alternatives:

These DYU models offer foldability, reliable performance, and transparent warranty policies, which stand in stark contrast to the unverified safety claims surrounding cheaper imports. Plus, the Back‑to‑School Sale's value helps ease costs for students and families budgeting for campus life.
A Broader Industry Perspective
The recall serves as a painful reminder of the price of cheap convenience. Devices powered by lithium-ion batteries, from hoverboards to scooters, have a history of safety issues—many prompting industry-wide agreements to standardize certification after past fires and recalls. Yet, many e‑bike manufacturers continue to evade rigorous testing, prioritizing sales over safety.
UL testing can cost anywhere from $30,000 to $100,000 per model, which explains why budget brands avoid it—but this cost pales in comparison to the financial and human toll of battery fires.
City-level policies are responding—New York City’s 2023 mandate and California’s impending 2026 law are steps forward. Still, without federal mandates, these efforts remain fragmented and reactive, not preventative. For now, shoppers are advised to look at brands like DYU, which, while their specific UL status may need confirmation, offer clear structure, warranties, and transparent sales models—qualities often absent in off-brand e‑bikes flooding online marketplaces.
What Students and Parents Should Do
- Research Before You Ride: Always check if an e‑bike and battery are UL 2849/2271 certified. Look for that sticker or ask the retailer directly.
- Consider Value Over Price: A slightly higher upfront cost with a reliable brand like DYU may save cost and stress down the line, especially during a major Back‑to‑School purchase season.
- Take Advantage of Current Deals: If you're shopping now, the DYU Back‑to‑School Sale, which includes popular models like D3F, C3, and C9, offers strong pricing paired with built-in safety features, warranties, customer support, and brand reliability.
Final Thoughts
The recall of 24,000 VIVI e-bike batteries is a clear warning of the risks inherent in the rapidly expanding e-bike market—cheap, uncertified products can quickly become dangerous liabilities. With at least three fires reported—but thankfully no injuries—this is not a wake-up call; it's a siren.
For American consumers, especially students and families investing in affordable, eco-friendly transportation this fall, the message should be clear: don't compromise safety for savings. Options like DYU's D3F, C3, and C9, widely promoted in their Back-to-School deals, offer a smooth, stylish, and safer ride forward—right when reliability matters most.
