According to Zero, these are most likely the first electric vehicles to ever complete the rugged Rubicon!

Video description:

"Five riders from the Zero Motorcycles R&D crew tackled the famous Rubicon Trail in October. All five completed the rugged off-road trip, becoming (as far as we know) the first to do so on electric vehicles. Bonus points for accomplishing the feat on essentially stock Zero motorcycles. All in the name of "product testing."

"Congrats to Jamie, Josh, Micah, Luke and Kyle! And, a tip of the helmet to the Zero FX for its trail worthiness (the motorcycles each finished with about 50% battery remaining)."
