That's right, tall, amphibious, and with a couch.
Why? That's a good question...
The whole notion of an amphibious tall couch trike is the beer-induced brain child of a Rat Patrol member, I am simply the conduit between a fantasticly absurd idea which should never have been done, and something that now exists and is actually practicle to use in the real world... But it at all started with beer.

Step 1: Beer
First we sat down and thought about the ergonomics of our world-beating Steer-by-beer concept — would it be easy enough to ride, steer AND drink beer at the same time. Some things are more important than others. A few beers later and we were satisfied it could be done.
Fortunately, I had picked up an old bunk bed frame the week before, it seemed to be about the right size and shape...

Step 2: More beer
It had to be a tallbike so that the eye level of the pilots would be well above that of all but the tallest pedestrians (good for concerts and the like)...
Also, the couch had to be easy to remove for parties (4 bolts) and the like... good idea! Steer-by-beer was totally going to work!
Now we set about setting the pedal distance before making final decisions about the dimensions of the chassis.

Step 4: Floatation & beer
Floatation was quite an issue. It had to float yes, and while it would be OK if things dropped off here and there, it HAD to be UNSINKABLE. You know what they say about the dangers of mixing beer and water...
I figured (hoped) about 300 litres would be fine... I cut the bottom out of the plastic barrels, scuffed the joining surface, then after they had been sitting in hot sun for a while, a few of us smashed them together using epoxy resin and a huge piece of wood... of course, beer played it's part too :)
All of a sudden, the whole structure was totally rigid — wow, it worked really well!! Next we drilled a 10cm dia hole in the side of the barrels, close to the end. So now we had bulkheads, which were filled with expanding polyurethane foam. Bomber.
Next, I used angle iron to make the float base, which had nylon strapping going through lugs to attach the floats. So far so very good.

Step 5: Floatation, beer and propulsion
Seing as we were already building a tall trike with a serious inherent danger of off-camber cornering disastery, I thought it would also be great to have a reliable 360degree-turning system, allowing it to (theoretically) spin on it's own footprint in traffic.
The floatation frame attaches with only 4 bolts, the floats weigh about 80kg, so it needed to be able to just drop off when required.
So once the drive train was attached and working, we needed an aqua propulsion system — my idea was to use propellers, but that would have become caught in weeds and stuff, quite the hassle when all you want to do is drink a beer.
Fortunately I had outsourced the design, build and installation to some other Rat Patrollians... their idea was to use paddle wheels — it worked (slowly).

Step 6: Testing (with beer)
Finally it was time to ride this thing into the water (dry photo showing floatation barrels prior to strapping)... I was only guessing the placement of the barrels and wondered about it's stability in the water.
Funny thing is... IT WORKED PERFECTLY THE FIRST TIME!!!!!!!!! Didn't expect that. Mmmmm, beer, the sweet taste of success :)

Step 7: Living the dream
OK, it probably has a top speed in the water of about 1 knot, but it's a STYLISH ride! The cops aren't sure how to take this one, it's a bike but it's much bigger than a car... or is it a boat? We are quietly confident that she is legal in this country.

The first picture in step 7 is just glorious, definitely living the dream. If Randy hadn't beaten me to it, I would definitely have featured this.
Just one small thing... where's the video? Why haven't we seen the Tall Amphibious Couchbike pedalling gently off towards the sunset?
Here are a couple I found, one without the floats attached, one kinda dark launching into water at speed...
i have try to make it sir , but i have problem with a float ?
how to find them
The other problem with adding a motor is that you get into boat registration territory in many states. Here in Texas, even a tiny electric trolling motor means registering your kayak the same as if it were a speedboat with a big motor. And beer-drinking plus motorized craft equals a DUI most places as well. Best to stick with people-power.

Fantastic i wish i had one
thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks thanks
Really though, i thought the Rat Patrol only thrived under the shadow of Chicago scrappers...you learn something every day...
