Questions Riders Often Ask
Are electric bikes required to be UL certified by law?
In some places, yes. New York City has banned the sale of uncertified ebikes and batteries since 2023, and California has required UL 2849 or EN 15194 for every ebike sold in the state since January 1, 2026. There is no federal requirement yet. Euphree certified every model before either rule took effect.
What happens if an ebike is not UL certified?
An uncertified pack has not been tested for overheating, short circuits or thermal runaway, which is what turns a small fault into a fire. It also cannot legally be sold in New York City or California. FDNY guidance is blunt about it: do not buy or sell devices or batteries unless they are certified to UL safety standards.
What is the difference between UL 2271 and UL 2849?
UL, Underwriters Laboratories, writes the safety standards. UL 2271 covers the battery pack on its own. UL 2849 covers the whole electrical system together, motor, controller, charger and wiring. An accredited lab has to test the bike against them. Euphree's testing was done by SGS under certification ID SGSNA/24/CQ/00032.
How do you charge an ebike battery safely?
Plug the charger straight into a wall outlet, not an extension cord, and charge on a hard floor away from anything that can burn. Not in a bedroom and not blocking a door or window. Use only the charger that came with the bike. If a battery smells odd, changes shape, leaks or makes noise, stop using it and call 911. See FDNY's full guidance for retailers and riders.
