Some people call it "The biggest backflip ever over a road gap."
It is much possible it is. Josh Daiek is the Evel Knievel performing this massive stunt over Highway 50 in in South Lake Tahoe, CA.
"Took two tries to ride ‘er out! I’ve been eyeing this gap for the last decade. With a banner year in the Sierra last season the landing finally filled in and was ready to send. The gap was roughly 150’ (50 meters) take off to landing and over 100’ (33 meters) vertical drop! So stoked to check this one off the list!"
