a simple tec from 100 years ago that is mostly forgotten is the fact that they used paper over a wood body to make boat, carts. They varnished with 4 or 5 coats which made it water proof and stable. Simple to repair if damaged. Got the info out of popular mechanic mags when someone build a small boat using the method. It would make a interesting light way to cover a slip streamed body. Anyway just an old strange way of building things. They used a heavy brown butcher type paper.

Seems like that would be heavy. The other issue that Craig Vetter addressed is cross wind. A full length fairing is a lot of area that is susceptible to cross wind which is why he and others leave a space between front and back sections.

In the mid-seventies I built a chopper based on a Honda XL-350. The frame was cut down to a drop-centre form which, combined with a lengthened swingarm suspended with shorter shocks, made for a radically lower riding position. Of course the rear mudguard (fender) had to be moved up higher in the frame.

A small tombstone windscreen was attached to the handlebars and performed good duty in protecting the rider from the airstream.

Road rubber went on the wheels and the gearing was changed by a factor of increasing the number of teeth on the drive sprocket. Engine speed was far lower than a stock XL, and the fuel consumption was in the region of 80-85 m.p.g. Imperial (66-71 m.p.g. US).

This machine is shown in the middle of this line-up:


Its difficult to pick-out the rider's seat (the rider's back-rest is visible) but its not much higher than the kickstart pedal & carburetor. When footing the machine stationary; the rider's legs were bent sharply. You could almost place a fullface helmet on the seat and still straddle that! The front forks remained standard Honda and the steering worked well at speed, but tended to flop at slower paces.

If that had been fitted with a full dustbin fairing it would have needed higher gearing and 90+mpg Imp may have resulted. The 350cc single is one of the most fuel efficient displacements when balancing speed and usability. 125-200 cc sizes may achieve better but speed during hill-climbing would be sacrificed.

Aren't you a dead man pretty much the first time a semi blows by you at speed or at the first good unexpected gust at the wrong time if you use two wheels? On race tracks or salt flats it's one thing, but when just a few feet the wrong direction could put you into something solid, or worse something going the other direction...

I jumped in actually because I had thought of this before but then decided a safer route, more usable machine all around would be to take a gy6 150cc scooter I have and hacking the motor and rear wheel out of and make what would look like a typical velocycle recument trike, two wheels in the front, one in rear like this:

Except at speed front steering a trike, I don't know, could be really scary if not well laid out.

You'd have to add a wheel, basic frame, and a little more work, but you could still use that scooter to start.



A 3 wheel trike is road legal as a motorcycle, same laws, you would need to maintain the VIN part of the frame somehow in it though, just fyi, but it's no different than a person making a chopper bike into a trike you still register and insure it as the original bike, it's just faired.
http://www.velomobiling.com/gallery2...c89b46bb78aa5e









I would want a long low bullet shape myself for high speed/long distance but there are all kinds of cool designs out there, just look on google images or whatever for velomobiles.






Many of those are human powered only, that's why there's gatorade in this next pic, but you get the idea.

I'd think a trike would be worse, no ability to dynamicly lean against the side wind or gust, much heavier construction. Trikes ( barring the MP3 design which can lean..) are notoriously unstable no matter what the configuration. You might as well admit you can't ride two wheels.

As one who has ridden semi faired in recumbent (zipper bubble fairing on a LWB recumbent) in traffic, they're no worse than riding an upright commuter bike.

Good looking trikes. Consider this 'though; is it wise to spend $15,000 to build a road machine with severe limitations (including being able to carry just one small-ish rider) just to save some gas?


Of all 250cc stock motor scooters sold in the US, the Morphous should have delivered the highest mileage figures. If the Suzuki Gemma had been imported, that may have been the only 250cc to challenge that.

THAT remains the rub! You spend a lot of money to get a vehicle with low-running costs, but blow your budget in the process.

"Carver tilting technology (the same technology licensed by Persu Mobility) makes three-wheel vehicles commercially viable for the first time ever by solving the stability issue inherent in non-tilting three wheel vehicles. The advantage of three-wheel vehicles is that they are lighter weight, use less materials and smaller batteries, and are more aerodynamic."

If this Persu Hybrid parallel hybrid costs as much as four 250cc maxis, who's going be the buying market for it?

Yes I would miss being able to lean also, two wheels is just too much fun and certainly lighter and better in the corners, only for sidewind like a semi blasting you off the road did I think I'd want 3 wheels.

I guess they already exist in s couple forms so it must be safe, here's some I just found:

I had no idea, then I found one vid and it led me to the rest.
Very interesting, I really want to try one of those out now that I've watched those in action. It looks like a blast.

I don't know about the op but I was thinking more garage built under 1k total using used/scrap parts most of which I already have.

I don't see a need for an electronic stabilizer system or a/c or anything fancy to start with, down the road maybe. If I were able to afford a project like this the most I would want to do is invest a little extra money in the shell and make it out of rivited aluminum panels to look like a vintage streamliner salt flat racer. I don't think I'd paint it though, just polish it.

I think the op was looking for more like this though right?

Check this out: 150mph with 50cc's.

Just for a better look at the outside of that one:

And inside:

Anyone have a spare aluminum canoe laying around?

You can see a couple of those and hear results of them and everything else in this video below. Nice for comparison to see what they're capable of. Speaking of comparison Shinyo Kamura's harley powered needle bike only reaches 100 in this.

Throw a bigger GY6 engine in it and you would have a pretty cool aerodynamic cruiser.
They make full GY6 swaps that extend the wheel base too.

Not cheap, but they're there.

I'd like to see that one...


Here's an amphibious trike with a 110 yamaha mio scooter motor, someone else thinks like me. ~300lbs total for the whole car (which is less than my 150cc scooter stock) and it says it does 70mph easily on the freeway.

See how light and strong an all alumunum chassis can be? Shape and then rivet that ladder into the bottom of the canoe and sheet over the top of that for a smooth floor, then fill the whole floor with expanded foam and it would be plenty strong and light, and the thing could never sink even if it weren't water tight.

I've sorta gone off track op, sorry. Maybe I should start another thread about my land speed looking floating canoe cruiser water battling scooter idea, I'm sure it's not at all what you had in mind.

Excuse me while I try to imagine how the motor would retract up inside to friction drive a prop. http://www.youtube.com/watch?v=lbDT0...eature=related

Or a jet ski propulsion system take off?
