They do exist...

I'd have to say that your bike as shown would have some obvious chain problems because the walking beam axle will change the chain tension as it articulates, if it doesn't have a sprunk chain tensioner to control it. (based on the obverse image on the source page)

otherwise a cool idea.. thank you

Juiced-up roller blades!

How do they keep the rear wheels from cross-skidding? (Unless there is sideways articulation.)

great stuff.

and has the chain on the same axis points (of suspension articulation)

I just can't see the advantage of this design over say..a tricycle design if what you want is more traction and stability. (As I get older, the three wheelers get more interesting to me! )

The advantage lies in being able to date women with vast amounts of inner beauty and still being able to split the lanes when cruising through traffic.

Not intended to be a fat joke as I, myself, aint skinny.

ha ha ha heee hee hee

As I get older, the three wheelers get more interesting to me!

Me too. I see a big potential market for a single person trike transportation. My one gripe about some of the current trikes is the high CG. If you lower the CG and design correctly you have a low powered F1.

Ron

The Can Am Spyder might be of interest to you.

Again a high CG. I envision something on the order of a sports car height where you sit inside. Let me come up with a sketch. Now the front wheel drive engine/trans appears to be a natural for this (only moved to the rear). Thats like they did it on the Fiero.

Ron

Another way to lower the CG is to add weight. Perhaps this would have sufficient amounts to do so. It does look a bit plain. Maybe the designer can hook up with the kid in the caption this photo with the massive stereo on a bicycle. Between the two it should really look cool.

For those that prefer to stay on 2 wheels then maybe Roadog is the answer. It could split lanes and skulls. Yes it is a real bike. There were 2 made if I remember correctly.

I am talking something on this order.

Ron

Here an idea I think your looking for.

coool!

did you draw that? what software?

chris

If you are asking me, its just plain ole Google Sketchup. I use it for presentations and such as its easy. For finalized i use 3D turbocad as it dosent cost many thousands of $ like Autocd and does basically the same thing.

Ron

Seems like a fair idea. Two tires on the rear would provide more friction to prevent rear-end slide-out. Of course, unless you are racing, why bother with the complexity?

But you would have one heck of under steer with one front wheel. That is one of the downfalls of stander trikes. The Can Am Spider is a good way to deal with under steer.

Though trikes make is difficult to lane split.

What would be wild would be replace the rear wheel with a trike axle kit. Talk about a quad that would make.

But you would have one heck of under steer with one front wheel.

Ok ,so you articulate all 3 wheels, Using a normal FWD engine/tranny you are almost there.

Ron

I guess you could use some hydraulic components using the power steering pump to drive a cylinder to steer the auto wheels. Feed from the handle bar using articulation gear or something similar.

Though thinking about it some. If the front wheel looses traction the trike would most likely continue straight or at some odd angle the the driving wheels are pointing in.

Now some sort of independent wheel brake or cut brake on the rear like on a dune buggie or farm tractor could steer. BUT I don't know how safe at speed it would work especially in an under steer situation.

It seems pointless to me.

I have built an In-line three wheel motorcycle with two wheel steer and two wheel drive. The bike was built just to prove the concept, and it works well. You can see it being test on you tube http://youtu.be/W7DC4aJEBiA

Not got time to view it now, but that looks waaaaaay fun !
