    The U.S. Consumer Product Safety Commission (CPSC) is taking action to address the growing fire risks associated with e-bikes and electric scooters. In a new proposal, the federal agency outlines stricter safety standards for the lithium-ion batteries and chargers that power these popular devices. The proposed regulations aim to prevent fast-moving, destructive fires that often start in residential garages, basements, and entryways. Importantly, the rules target the manufacturing and sale of future products. Consumers will not have to discard the devices they already own.

    Rather than removing battery-powered rides from the streets, the CPSC wants to ensure they charge safely. The agency is proposing mandatory testing and design requirements for a wide range of transportation devices. This list includes e-bikes, e-scooters, hoverboards, electric skateboards, and unicycles. The rules also cover separate replacement battery packs, conversion kits, and third-party chargers. The proposal was officially published on June 24, 2026. The public can submit comments on the rules until August 24, 2026. If the standards become final, manufacturers will have a 180-day phase-in period to comply before their new products hit the market.

    The scope of this proposal is highly focused. It centers entirely on micromobility products and their power sources. It does not apply to the countless other lithium-ion batteries found in typical households. Devices such as laptop computers, cordless power tools, and full-size electric vehicles remain outside the boundaries of this specific regulation. Instead, the CPSC designed the rules to govern exactly how micromobility batteries are built, tested, labeled, and sold.

    The primary danger driving this federal effort is a phenomenon known as thermal runaway. This is a violent chain reaction that occurs inside a damaged or severely overheated lithium-ion battery cell. When thermal runaway happens, the battery can quickly generate extreme heat, toxic smoke, intense flames, and even explosions. This hazard is particularly severe because riders frequently store and charge their e-bikes and electric scooters in attached garages or inside their homes. In these storage areas, a failing battery is often surrounded by flammable materials like cardboard boxes, paint, propane tanks, or gasoline. A sudden battery failure in these conditions puts people, pets, and property at immediate risk of a catastrophic fire.

    The human cost of these fires has been significant. Between 2019 and 2023, the CPSC recorded 227 distinct incidents involving lithium-ion batteries in micromobility products.

    These sudden fires resulted in 181 injuries and 39 deaths. Investigators found that the charging process played a major role in many of the events, particularly in cases that resulted in multiple casualties.

    To combat these dangers, the proposed federal standard introduces several preventative measures. One major change requires battery cases to be highly resistant to tampering with standard household tools. This rule is designed to stop consumers from attempting dangerous do-it-yourself repairs. If a battery is swelling, leaking, smoking, or overheating, it is extremely dangerous to open it with a screwdriver. The CPSC wants to make it much harder for people to modify these highly sensitive power packs.

    The rules also demand rigorous new testing for charging systems. The CPSC wants to ensure that batteries have safeguards against issues caused by using the wrong charger.

    Additionally, the proposal includes protections to stop batteries from charging when temperatures reach unsafe levels. If the rule passes, aftermarket chargers will also be required to clearly list the exact product models they are built to support.

    Consumers will also see a major change in product labeling. The new rules mandate prominent warnings about fire and electric shock hazards. Labels will strictly advise against altering batteries and will provide clear instructions for safe charging. For example, riders will be warned to let their e-bikes cool down before plugging them in. The labels will also explicitly tell users not to open or repair parts that the manufacturer did not design for consumer servicing.

    For current e-bike and electric scooter owners, these proposed rules will not make their rides illegal overnight. The transition will be a gradual shift in the marketplace. If the regulation is approved, future shoppers will benefit from safer internal battery designs, highly visible warning labels, and chargers that clearly communicate their compatibility. By addressing the root causes of battery fires, the CPSC hopes to make the next generation of electric transportation much safer for everyone.

    In the EU the pressure is arriving through civil law rather than a new safety standard: from 9 December 2026, the EU's new product liability rules make it easier for an injured rider to claim against a manufacturer when a battery, brake or firmware defect causes harm, including defects introduced by a later update.
