Quick Answer: As of October 2026, the CPSC has an active fire-hazard recall or warning out on Rad Power Bikes (9 models, batteries HL-RP-S1304/RP-1304, 31 fire reports, no replacement offered — Rad Power says a recall “would immediately put Rad out of business”), VIVI (~24,000 batteries, free replacement available), FENGQS, Santa Cruz Heckler 9, Ridstar Q20/Q20 Pro, and Unit Pack Power (UPP) batteries. Check your exact model against the full list below, and if it’s affected, stop charging and riding it immediately rather than waiting for a convenient time.

Lithium-ion e-bike batteries are the single most common cause of a bike-related product recall right now, and the list changes often enough that a guide written even a few months ago can miss a new entry. Here’s every active CPSC electric bike recall or warning we could confirm, what triggered it, and what to actually do if your bike is on it.

This list changes as new incidents surface — always cross-check the current CPSC recall database directly before assuming a model is safe just because it’s not above.

The Rad Power situation is unusual — and worth understanding

Most recalls on this list follow a familiar pattern: CPSC flags a fire risk, the brand agrees to a remedy, and the brand pays for replacement batteries or refunds. Rad Power broke that pattern. According to CPSC’s November 24, 2025 warning, Rad Power told the agency that a full battery replacement program for the nine affected models “would immediately put Rad out of business” — the company had already disclosed potential layoffs of 64 employees in January 2025 and the possibility of shutting down without additional funding. Instead of a negotiated recall, CPSC published a public fire warning and told owners to remove the battery themselves and dispose of it as hazardous waste, with no replacement offered.

That matters beyond the nine specific models listed: Rad Power is one of the best-known direct-to- consumer e-bike brands in the US, and its financial condition means future safety issues on other models could play out the same way — a warning instead of a funded fix. None of the six current models in our best Rad Power bike guide use the flagged battery models, but if you own an older Rad with one of the exact model numbers above, that’s still worth confirming before your next ride. If you own a Rad Power bike that isn’t on the current list, it’s still worth registering your purchase directly with the brand so you’d be notified if that changes.

E-Bike Fire-Safe Charging Station / Storage Bag

Best for reducing charging risk on any brand · ~$40-80
  • A fire-resistant charging bag or storage box contains a thermal runaway event rather than letting it spread to the surrounding room or garage.
  • Useful on any e-bike battery, recalled or not — most lithium-ion fires trace back to charging habits, not just manufacturing defects.
  • Pair with charging only while awake and present, and unplugging once full instead of leaving it on the charger overnight.

How to check if your e-bike is affected

  1. Find your exact model name and battery model number — recalls are often tied to a specific battery part number (like Rad Power’s HL-RP-S1304), not just the bike’s marketing name, so two bikes with the same model name but different production years can have different battery hardware.
  2. Search cpsc.gov/Recalls directly for your brand name, not just “electric bike” — the search tool indexes by brand and product type.
  3. Check SaferProducts.gov if you want to see raw incident reports, not just finalized recalls — this is where a pattern has to show up before CPSC acts, so it sometimes has early signals a recall notice doesn’t yet.
  4. Register your bike with the manufacturer when you buy it. Recall notices go out based on registered contact info or retailer purchase records — an unregistered bike bought secondhand or with cash is the easiest one to miss a notice on. Our used electric bike guide covers what else to check when buying one that isn’t new.

What to do if your bike is on the list

Stop charging and riding it immediately. Don’t wait for a “better time” — CPSC’s incident reports across these recalls include fires that started during storage and overnight charging, not just while riding. Then follow the specific remedy for your brand: VIVI and Santa Cruz both offer a funded replacement or inspection process, while Rad Power and the warning-only brands (FENGQS, Ridstar, UPP) currently require the owner to remove and dispose of the battery with no brand-funded replacement. If you’re not sure which category your brand falls into, CPSC’s recall or warning notice for that specific model spells out the remedy — check it before assuming a free replacement is coming.

The bottom line

Six brands have an active CPSC fire-hazard recall or warning on e-bike batteries as of October 2026, and the list has grown steadily since the first UPP warning in 2024. Most are straightforward: stop using the battery, get a free replacement. Rad Power is the exception that’s worth remembering — a major DTC brand that told CPSC it can’t afford to fund its own recall, leaving owners to dispose of the battery with nothing offered in return. Check your exact model and battery number against the list above, and if you’re shopping for a new e-bike rather than troubleshooting an existing one, our best electric bike roundup and electric bike brands guide only recommend models with no open fire-hazard warnings as of this writing. If your bike is older or secondhand, our electric bike maintenance guide also covers the charging habits — using the OEM charger, never charging unattended overnight — that cut fire risk on any battery, recalled or not.
