The U.S. Consumer Product Safety Commission told owners of three Rad Power Bikes battery models to stop using them immediately after receiving 31 fire reports tied to the products. The federal warning, issued under Product Safety Warning 26-118, names battery models RP-1304, RAD-S1304Y, and HL-RP-S1304, stating the packs can “unexpectedly ignite and explode,” especially when the battery or its wiring harness is exposed to water or debris. Twelve of those 31 incidents caused property damage, and the agency warned of the risk of serious injury or death.
Why the CPSC warning on Rad Power batteries demands attention now
The CPSC did not issue a voluntary recall here. It issued a standalone safety warning, a less common step the agency takes when it believes the hazard is severe enough to act before a formal recall agreement is reached with the manufacturer. That distinction matters for owners: there is no structured replacement program, no prepaid return label, and no refund process in place. Riders who own one of the three affected battery models are simply told, in the official federal warning, to stop using and charging them right away.
The agency’s language is direct about the trigger: water and debris reaching the battery or harness can set off ignition. That raises a practical problem for e-bike commuters. Bikes are routinely ridden in rain, splashed by puddles, and stored in garages or sheds where condensation, dust, and grit are common. A hypothesis that these fires cluster among batteries charged or stored outdoors or in non-climate-controlled spaces is plausible on its face, but the publicly available incident data does not yet confirm that pattern. Individual consumer reports filed on SaferProducts.gov describe fires during indoor charging as well, including at least one case of thermal runaway while a battery was plugged in inside a home.
Incident records and Rad Power’s response on file
The 31 fire count comes directly from the CPSC’s own incident tracking. Among the individual reports accessible through the agency’s public database, one filing describes a charging battery that burned a bedroom in a two-story home. The consumer’s account uses the phrase “thermal runaway,” the term for the cascading cell failure that causes lithium-ion batteries to vent hot gas and flame in rapid succession. Photos attached to that report show fire damage well beyond the battery itself.
Rad Power Bikes has posted at least one manufacturer response through the SaferProducts.gov platform. In a filing tied to a separate incident report, the company directed riders to follow manual instructions and to discontinue use if damage to the battery is visible. That guidance, visible in the company’s public incident response, tracks with standard lithium-ion battery safety advice but does not address the specific failure mode the CPSC identified, namely ignition triggered by water or debris exposure during normal use conditions.
The gap between the company’s public statements and the agency’s warning is notable. The CPSC warning does not describe a defect that appears only after visible damage or misuse. It describes batteries that can catch fire when exposed to environmental conditions that any outdoor vehicle will encounter. That framing puts the burden on riders to treat a product designed for outdoor transportation as too dangerous to expose to the outdoors.
What Rad Power battery owners still do not know
Several questions remain open. The CPSC has not published laboratory test results or an engineering analysis showing exactly how water or debris triggers ignition in these three battery models. Without that data, owners cannot assess whether a protective case, a sealed harness connector, or a simple wiring inspection would reduce the risk. The agency’s internal watchdog, the Office of Inspector General, oversees the commission’s operations, but no public audit of the battery investigation process has been announced.
Rad Power Bikes has not disclosed internal quality records, warranty claim data, or any timeline for a formal recall that would include a remedy. The company’s SaferProducts.gov responses reference manual compliance and visible-damage checks, but 31 fires suggest a failure mode that goes beyond user error or obvious physical damage. Whether the company will offer battery replacements, refunds, or a retrofit fix is unknown, and the lack of a recall means there is no binding schedule for those decisions.
The outdoor-storage hypothesis, the idea that most fires trace to batteries kept in humid or temperature-extreme environments, cannot be tested with the information currently available. The CPSC’s public incident summaries do not consistently include storage conditions, charging location, or weather data. Mapping those variables across all 31 reports would require access to the full, unredacted case files, which the agency has not released. Until that happens, both regulators and riders are working from a partial picture of how and when these failures occur.
Immediate safety steps for affected riders
For owners of the RP-1304, RAD-S1304Y, or HL-RP-S1304 batteries, the immediate step is straightforward but costly: stop using and charging the battery, remove it from the bike, and store it in a location away from living spaces and flammable materials. A detached, well-ventilated structure is preferable if one is available. The goal is to minimize the chance that a spontaneous failure will ignite surrounding contents or cut off escape routes.
Owners should avoid attempting home repairs, opening the battery casing, or modifying the wiring harness. Lithium-ion packs are tightly engineered systems; puncturing cells or disturbing internal connections can increase the risk of thermal runaway. If the battery shows any signs of swelling, unusual odor, hissing, smoke, or excessive heat, it should be moved-only if it is safe to do so-to a noncombustible surface and away from people, and emergency services should be contacted.
Because no recall remedy exists yet, disposing of the battery is not as simple as putting it out with household trash. Local hazardous waste programs or e-waste collection sites are often equipped to handle lithium-ion batteries, and some municipalities require drop-off at designated facilities. Riders may face fees or long wait times, which adds to the practical burden of complying with the CPSC’s warning in the absence of a manufacturer-funded solution.
What to watch for next
Two parallel tracks will determine how this story develops. On the regulatory side, the CPSC could move from a warning to a negotiated recall if it secures agreement from Rad Power Bikes on a remedy. That would likely spell out whether affected owners receive replacement batteries, partial refunds, or some other compensation. It would also clarify logistics such as return shipping, disposal, and timelines.
On the corporate side, Rad Power’s choices will signal how the company balances liability, customer trust, and cost. A proactive recall or voluntary replacement program would address the safety risk more directly but at significant expense. A narrower response focused on updated manuals or rider education would leave more of the risk management burden on consumers and local fire departments.
In the meantime, riders who depend on their e-bikes for daily transportation are left in a bind. Using the flagged batteries means accepting a documented fire hazard; parking the bikes until a remedy appears may be economically or practically untenable. That tension underscores why the CPSC’s unusual decision to issue a warning without a recall has drawn such close attention: it acknowledges a serious risk but does not yet offer a clear way out for the people most affected.
