“However, the range isn't set in stone. It can vary based on the rider, terrain, battery condition, and many other variables. Also, it's best to reduce this value by 15% so you can get a more realistic estimate. For instance, the Addmotor GRANDTAN, our most versatile mid-ranger, averages a range of 85 miles of PAS1 at 8mph. With PAS7 at 20mph, this is reduced to 40 miles on a single charge.”

    Applies in: United States, and Canada under the matching listing QGNS7.E540364

    UL's register lists ADDMOTOR TECH under file E540364, UL Certified for Electrical Systems for E-Bikes. It names the family GRANDTAN rather than individual variants, so whether this variant is covered is not stated. The Grandtan Turbo is a mid-drive where the rest of the family are hub-drives, which a family-level listing does not separate. UL certified it; we did not test it.

Each standard listed is an independent claim about this specific product — one standard does not imply compliance with another.
