UL Certification 

UL 2849 (E-Bike Certification)

As of February 2018, the Consumer Product Safety Commission (CPSC) noted UL 2849 as the expected electric system safety standard to ensure the safety of e-bikes and electrically power-assisted cycles (EPACs).

UL 2849 covers:

• E-bikes (typically sit-to-operate and over-the-road use) and pedelec (pedal assisted electric) bicycles.
• The risk of electric shock during charging over the life of the product and other potential electrocution hazards.

UL 2849 is the gold standard of electric bikes.  Underwriters Laboratories is familiar with the technical requirements for testing and certification.  By tapping into their technical expertise and testing capabilities, UL 2849 offers the highest levels of regulatory acceptance and market recognition in the industry.  It helps get safer products to market- an important responsibility for all e-bike manufacturers.
