  • Description




     
    As the very name implies, Fat Bear Ebike shows its strength in both driving force and battery life as strong as a live fat bear. The strength all comes down to the cooperation of a 500w electric motor exclusive for an Intelligent power assist system (I-PAS) and one integrated 48volt,11.6ah battery with Samsung cells. 





    The innovative l-PAS technology transfers the energy generated by the motor back to the generator when riding downhill, braking, or gliding. While the bike doesn't require throttle during these moments, the motor uses the kinetic energy to power the battery.
