The electric bike trend continues, and electric assisted bikes are being touted as a way to help make climbs easier for those on two wheels. Now a similar electrical concept is catching on for snowboards.
This is where the Propul~surf comes in. It basically takes the Archimedes design of a screw to create forward momentum. This concept was used for centuries to raise water and apparently it could help snowboarders get up a hill as well. We of course though that was what the ski lift was for!
