The Consumer Product Safety Commission has proposed a sweeping safety rule that would fundamentally alter how e-bikes are designed, manufactured, and sold across the United States. The regulation targets lithium-ion batteries and electrical systems, the two areas where most e-bike failures and safety incidents originate.

The proposed rule establishes stricter testing and certification requirements for battery packs, charging systems, and motor controllers. Manufacturers must demonstrate that their products meet enhanced thermal safety standards, preventing the battery failures that have caused fires in homes and warehouses. The CPSC also mandates labeling requirements that clearly communicate voltage, wattage, and safe operating procedures to consumers who may lack technical knowledge.

For the e-bike industry, compliance carries real costs. Smaller manufacturers and startups face the heaviest burden, as they lack the resources of larger players like Trek, Specialized, and Giant to absorb new certification expenses. Some direct-to-consumer brands operating on thin margins may exit the market entirely or raise prices substantially.

The rule also establishes age restrictions and operational safeguards. E-bikes classified as Class 2 and Class 3 models, which offer throttle assistance and higher speeds, face additional requirements around speed limiting and motor cutoffs. The CPSC recognizes that these more powerful machines pose greater injury risk, particularly for younger riders.

Consumer advocates and safety organizations have championed the proposal, pointing to a spike in e-bike battery fires over the past three years. The National Fire Protection Association documented hundreds of incidents linked to substandard batteries and improper charging practices, many involving cheaper imports lacking basic safety certifications.

Manufacturers have pushed back on the timeline, requesting a 24-month transition period rather than the 18 months initially proposed. Industry groups argue they need adequate time to retool production and source compliant components from suppliers.

The rule enters public comment period soon, with implementation expected
