US may or may not regulate e-bike batteries

Federal regulators and CSPC are considering obligatory standards for small e-mobility device battery systems. The US Consumer Product Safety Council has – unusually - published in May 2025 (“noticed”), but then unnoticed, then re-noticed in June, then again unnoticed, a proposed federal Rule on lithium-ion batteries and related electrical systems in micro-mobility devices (e-bikes, scooters, hoverboards …). The (un)proposed draft Rule would require products sold to meet the following Standards: e-bikes  UL 2849-20, e-scooters and hybrids L 2272-24, user replaceable battery packs UL 2271-23 and also battery enclosure, post-discharge charge test, and reverse polarity test requirements.

At the same time, the House of Representatives has passed Bill HR973 directing the CPSC to issue mandatory federal standards for lithium-ion batteries in micro-mobility devices, citing the same three UL standards. A sister Bill S389 has passed the Senate Committee stage and is pending full house consideration.
