Build a recumbent bike that is enclosed and make the shell waterproof and shaped properly to allow it to work as a hull, like a canoe. You'd start with a three-wheel bike, to get the steering wheels outside the waterproof area-something like this, but probably no windshield (I want out if it's sinking)

You'll need to power the drive wheel either with the chain going down from above the water level or with a shaft, (which can be sealed watertight) like this:

I think the back wheel has one-way vanes connected on a ring that can deploy them together using a float to serve as a paddle-wheel. The float is so they only drag while you are in the water.

Tandem or even three-seat would be even better. I bet people would pay to rent these at a beach or lake and you wouldn't even need a dock.

I see patents for bike/boat, but nothing like this. Has this been done?
