Kinetic Sculpture Racer (for the glory!) Transphibian Bicycle

How to convert a bicycle and inflatable boat into an effective kinetic sculpture racer, amphibious human powered craft, or general burn or parade vehicle.

In addition there will be bonus parts consisting of retractable flapping wings made from table lamps, a nsfw pneumatic tail, and a helmet with rotating portal to other dimensions.

The sculpture demonstrated here won the PEL(pelican= completed all challenges) and Roadrunner (first to finish) in the 2010 Klamath Kinetic, and the PoohBah prize ($100 cash) in the DaVinci Days KSR.   My first 2 events netted 3 prizes.

The point really is the fun and joy of sharing your art with everyone.
Kinetic Sculpture Racing was founded in Arcata CA years ago, to enable adults to have fun, and thus to demonstrate to children that growing up is safe.
Kinetic Sculpture Racers must ride on road, dirt tracks, through a mud and sand pit, and into, through the water and out of the water, without pushing.  Not Easy.

A little intro about the bike and kinetic sculpture racing.

Disclaimers:  Bike and Boat really float, not good for bearings or steel. Wear a life jacket.  Tie the bike to the boat when on the water.
Wings: won't really hold you up, don't jump expecting to be caught
Tail: Use at your own risk
Inter-dimensional Helmet:  Where was I?

Step 1: Ingredients and Tools

Main Ingredients: 
Racer:

Bicycle, I have used my cargo bike which is about 20" longer than a normal bike, but I think a regular mountain bike would do just fine.  Low gears are needed for sand and mud. needs a rear rack.  and front mounting bracket for flotation.
Flotation, I used a Syvelor  Tahiti two person kayak, though other similar inflatables should work
2 6'x 1"od  aluminum tubes
2 handlebars from an old bike
4 bar end handle grips
20' of 1" webbing for lashing the floats to the tubing
2 1" x 2" x 28" hardwood boards
1 BMX handle bar stem.
1 Paddle

 
Wingset:
A bunch (6 maybe) articulated bench lamps
1 Photo development projector base
1 Back pack
1 Bellows pump
3 yards of wing covering. I used mesh but that's your call

Monkey Tail:
1 Bicycle inner tube
1 1/16" brass welding wire
1 tuft of fur (optional)
1 small fanny pack
1 detergent bottle neck
1 plastic cylinder to conjoin the tube ends

Inter-dimensional Headgear:
1 Helmet (Probably the older the better as it needs solid fiberglass shell to mount to.
1 Washing machine impeller
1 1" x 3" 1/8" aluminum mounting plate
1 12" x 3/8" all thread and 4 nuts
1 scooter wheel
1 transmission oil funnel

Tools:  
(I have a full prototype shop, but I am going to try to set this up for minimal tools and skills.)
A drill motor is needed along with assorted bits
Hacksaw
Razor Knife
Pliers, wrenches and various drivers to match your bike and hardware
Tubing bender to bend the aluminum tube.

crazy cool ! more pics would be nice for us ram challanged users. Can you provide more info on your propdrive hack please

Will do l8nite, Sorry about the bandwidth, will drop some stills in the mix.

I am trying to get a comprehensive shot of all the parts (bike, boat, wings etc., finishing wings up right now. )on the page. I was rushed to get the contest entry in and as such many details are missing. Also, I can't find the photos I took already but can take more.
What I thought was really cool is that both the angle drive and prop are of the correct rotational direction to go forward relative to the pedaling direction. Also the 2 to 1 ratio of the angle drive helps get the ideal pedal to prop speed, i copied what propel does. Harbor freight doesn't seem to make a Milwaukee knock off, so you will need to hunt down the angle drive.
