CPSC Sets October 21 Hearing on Proposed E-Bike Battery Safety Rules

Last Updated on October 9, 2026 by Kristina

October 9, 2026 | United States

The U.S. Consumer Product Safety Commission (CPSC) will hold a public hearing on October 21, 2026, to consider comments on proposed federal safety requirements for lithium-ion batteries and electrical systems used in e-bikes, e-scooters, and other micromobility products. For shoppers considering battery safety, my guide to UL-certified e-bikes explains what electrical safety certification means.

The proposal addresses battery failures that can cause fires, explosions, serious injuries, and deaths. It could eventually establish more consistent federal safety requirements for manufacturers and importers.

The important thing for e-bike owners to understand is that these requirements are still proposed. No new mandatory federal battery safety standard has taken effect as a result of this hearing announcement.

Current Status: Hearing Scheduled, Rule Not Final

As of October 9, 2026, the CPSC proposal remains in the federal rulemaking process.

The agency published its original proposed rule on June 24, 2026. A separate Federal Register notice published October 5 announced the opportunity for oral comments.

Here are the key dates:

Event	Date
Original proposed rule published	June 24, 2026
Original written-comment deadline	August 24, 2026
Public hearing announcement published	October 5, 2026
Deadline to request an oral presentation	October 15, 2026, at 5 p.m. Eastern
Virtual public hearing	October 21, 2026, from 10 a.m. to 1 p.m. Eastern
Final rule and effective date	Not yet established

The October 15 deadline is specifically for people requesting to speak at the hearing. It is not an extension of the original written-comment deadline.

The October 21 hearing is an opportunity to present comments, not an announcement that a new standard has been finalized.

What Is the CPSC Proposing?

The CPSC wants to establish mandatory federal safety requirements for lithium-ion batteries and electrical systems used in covered micromobility products.

The proposal would incorporate three existing voluntary safety standards, with additional requirements and modifications.

The Three UL Standards

• UL 2849:2020: Covers electrical systems for e-bikes, including the interaction of batteries, chargers, and other electrical components.
• UL 2272:2024: Covers electrical systems for personal e-mobility devices, including certain e-scooters and other covered devices.
• UL 2271:2023: Addresses batteries used in light electric vehicle applications, including user-replaceable battery packs covered by the proposal.

These standards serve different purposes. A battery’s compliance with UL 2271 does not automatically mean the complete e-bike electrical system complies with UL 2849.

The proposed rule would make applicable requirements mandatory for covered products, with additional changes intended to address known battery hazards.

Additional Battery Safety Protections

The CPSC is also proposing specific protections, including:

• Tamper-resistant battery enclosures: Intended to reduce unsafe access to or modification of battery components.
• Charging-temperature safeguards: Battery management systems would be required to prevent charging under certain unsafe high-temperature conditions.
• Reverse-polarity testing: Intended to address electrical hazards involving incompatible or improperly connected chargers.
• Additional warnings and instructions: Including safer charging practices and information about battery modification and other hazards.

These proposals address more than whether a battery has a certification label. They also consider how the battery, charger, electronics, and complete electrical system interact.

Replacement Batteries, Chargers, and Conversion Kits

The proposed rule also addresses certain separately sold replacement battery packs, aftermarket chargers, and components associated with e-bike conversion kits.

This matters because some riders purchase replacement batteries from third-party sellers or install electrical conversion systems on traditional bicycles.

If a final rule is adopted, its exact requirements will depend on the product categories, definitions, and compliance provisions included in the final regulation.

Why Is the CPSC Considering New Battery Requirements?

One of the major concerns is thermal runaway, a dangerous process in which a battery cell overheats and produces heat that can spread to surrounding cells.

Thermal runaway can lead to rapidly developing fires, explosions, or the release of hazardous gases.

According to the CPSC’s original proposal, the agency identified 227 incidents between 2019 and 2023 involving covered micromobility products that potentially could have been prevented by the proposed requirements.

Those incidents included reports involving fires, explosions, gas releases, burns, overheating, and smoke inhalation.

The identified incidents were associated with 39 fatalities and 181 injuries.

These figures cover multiple micromobility product categories, not just e-bikes. They are also not a complete national count of all lithium-ion battery incidents.

The CPSC is considering mandatory requirements because the agency believes existing voluntary standards and current industry compliance have not sufficiently reduced the risks.

What Could This Mean for E-Bike Owners?

If the CPSC eventually adopts a final mandatory standard, manufacturers and importers of covered products may face additional requirements for battery and electrical-system safety.

For shoppers, consistent mandatory requirements could help make electrical safety information more meaningful across different brands.

However, several important questions will depend on the final rule, including its exact product coverage, compliance requirements, and effective date.

Existing e-bike owners should not assume they must replace their batteries because of this hearing announcement.

The hearing does not itself create a nationwide recall, prohibit existing e-bikes, or require every owner to purchase a replacement battery.

Anyone shopping for a new e-bike should still pay attention to manufacturer safety information, compatible replacement parts, verified certification claims, and reliable customer support.

How to Attend the October 21 CPSC Hearing

The CPSC has scheduled a virtual hearing that is open to the public.

Hearing details:

• Date: Wednesday, October 21, 2026
• Time: 10 a.m. to 1 p.m. Eastern
• Format: Virtual webinar
• Attendance fee: None

If You Want to Speak

Individuals wishing to make an oral presentation must email the CPSC Office of the Secretary at cpsc-os@cpsc.gov.

The request must include the written text of the presentation and use the caption:

“Lithium-Ion Battery NPRM; Oral Presentation”

Requests must be received by 5 p.m. Eastern on October 15, 2026.

Nonpresenting attendees are not subject to the October 15 speaker-request deadline.

Registration instructions are available in the official CPSC October 21 hearing notice.

What Should E-Bike Owners Do Right Now?

You do not have to wait for a new federal standard to take battery safety seriously.

Here are some practical precautions:

• Use the battery and charger specified or approved by your e-bike manufacturer.
• Avoid charging a battery that is swollen, leaking, damaged, unusually hot, or giving off a strange odor.
• Do not open battery packs, replace individual cells yourself, or bypass protective electronics.
• Check manufacturer notices and the CPSC recall database for safety alerts affecting your equipment.
• When purchasing a new e-bike, look for verifiable third-party electrical-system certification rather than relying only on unsupported marketing claims.
• Follow manufacturer instructions for charging, storage, and battery replacement.

Safety First: If you notice smoke, sparks, swelling, unusual heat, damaged wiring, or a strong chemical odor, stop using and charging the e-bike. Do not attempt to open or repair a damaged lithium-ion battery. Move away from the hazard and contact emergency services if there is a fire or immediate danger.

My Take

I think the most important part of this proposal is the effort to make battery safety requirements clearer and more consistent.

E-bike owners should be able to understand whether an electrical system has been properly evaluated, whether a replacement battery is compatible, and what a manufacturer’s safety claims actually mean.

I am especially interested in how the CPSC handles replacement battery packs, aftermarket chargers, and conversion kits. Those products can create difficult decisions for riders who want to keep an older e-bike operating safely.

I also want to see how a final standard would affect product affordability, replacement-part availability, and support for existing owners.

For now, this is a proposed federal rule, not a finished requirement. The October 21 hearing is another step in the process, and I will be watching for the agency’s next decision.
