Safety certification: UL 2849: most models, confirm this one. Heybike states: “"UL 2849 Safety Standards" on some models and "In accordance with UL 2849" on others, which is not the same claim” (source). That is the manufacturer’s own claim, not something we verified, you can check a specific model in UL’s Product iQ database. Why this matters.
