Mike Patey, the guy who built the amazing bush plane "Draco" is back with a vengeance with "Scrappy". And the bikes are pretty impressive themselves.

Not only do these bikes mount underneath Scrappy’s wings, but the electric bikes are charged by solar panels on each wing.
Scrappy itself began life as a CubCrafters Carbon Cub EX3 bush airplane. The plane is powered by Lycoming opposed eight-cylinder 780ci that produces more than 600 hp. The airplane rolls on huge Alaskan Bushwheel tires.
