    A motor on this Hydrofoil Waterbike would be a no brainer.

    Just like one of the comments.... "Sure wish we could see the drivetrain!!"

    WOW!! If only that could be combined with the pedaled aircraft...

    Imagine that thing with a 10hp Morinini engine strapped to the pedal mechanism :grin5:

    My brother's got a pair of those things, but with dual pontoons. His has a standard bicycle peddle/chain driving a sprocket on a small right angle gearbox, with a small prop on the end of what appears to be a half-inch stainless shaft that comes out of the gearbox. The gearbox/shaft are tilted at about a 30 degree angle, so that the prop is below the waterline.

    So, with his, you could either use something like a jackshaft setup on Happy Times, feeding power in before the gearbox, or you cut the output shaft, add a freewheel arrangement w sprocket there, and feed the power after the gearbox.

    There's another, similar looking bike called hydrobike. It has a chain drive from pedels to the drive unit, a sprocket/chain in a sealed housing to below the water line, and a right-angle set of gears below water. (Ring/pinion gear arrangement)

    [HR][/HR]But with a 10 Hp Morini engine powering the prop via the jackshaft, it would be pure evil on water, not to mention a cadence of 1300 :devilish:
