eGen Flex™

eGen Flex™ electric hybrid provides revolutionary capabilities and fully electric propulsion when you need it for up to 10 miles each charge depending upon duty-cycle, without the added infrastructure requirements of full EV. Our advanced technology provides geo fencing capabilities to switch to full electric mode when entering zero emission zones or depots, eliminating emissions and reducing noise levels, specifically in highly populated areas.
