Missing is the downtube, seat tube, bottom bracket, chain wheel,
chain, freewheel, front draileur, rear derailure, shifters, cables,
and rear brakes. With two rotating headsets, you can play hook and
ladder steering. Looks interesting but no clue how easy it is to
ride. During most of the video, the rider was coasting.

I spent some time trying to envisage how that thing could be ridden
with the pedals behind what looks like a conventional light weight
bicycle saddle.

Straddle the saddle and then reach back with your feet....

A swing fixie?

A unicycle with a training wheel?

A two-wheeled snakeboard?

I'm trying to figure out what's between the cranks and the rear wheel
hub. Probably some kind of freewheel or ratchet mechanism in the hub.

A unicycle with a training wheel?

A unicycle with a trailing wheel is a Penny Farthing. This one has a
leading wheel, which makes it a Farthing Penny.

A two-wheeled snakeboard?
http://en.wikipedia.org/wiki/Snakeboard

There have been articulated bicycle frames in the past:

Hmmm... if I do it right, I can make the bicycle almost go sideways.
That should be useful for clearing the bike path (or sidewalk).

Who asked the question that prompted this answer?

That be me. However, I didn't ask a question. I just posted the
links for yet another bizarre and interesting bicycle-like thing.
(I do that when I'm bored).

Then, there's Cannondale's concept bicycle for 2012:

http://bicycledesign.net/2012/09/cannondale-cerv-concept-bike/
Internal drive shaft and steering linkage. CERV means Continuously
Ergonomic Race Vehicle. Soon, everyone will be riding these.

I think Chalo meant "Why is this thing even being proposed?" And he's a guy who has built some unusual machines.

I think the answer comes from the world of "design school," as opposed to engineering school. From what I've seen, guys in design school get far more points for doing "innovative" than for doing "practical." Kinda like a bike box: It doesn't have to do anything beneficial to get rave reviews from some folks.

Specifics about the design:

1) What on earth do they claim that rear steering is for?

2) They're not much worried about KOPS, are they?
http://sheldonbrown.com/kops.html

3) 35" standover height? Is this to be marketed to basketball professionals?

4) Does anyone ride around in a 29" gear all the time?

5) I'm certainly not a weight weenie, but I do wonder what it weighs.

6) Um... did I ask what the rear steering is supposed to accomplish?

Slaves answer their masters. There is another way. A man, created
in the image of God, creates. He needs no orders to constrain his
thoughts, he has free will.

It could be further simplified by moving the pedals to the front
wheel, which would allow them to shorten the wheelbase even more by
making the back wheel very small.

wtf's a skateboard for?

do you know what a skateboard looks like?

3) 35" standover height? *Is this to be marketed to basketball professionals?

have you never ridden a skateboard?


4) Does anyone ride around in a 29" gear all the time?

I was a 29" waist at 19, I wore those Wranglers all the time, twice as
much when skatebiarding.


5) I'm certainly not a weight weenie, but I do wonder what it weighs.

Bananas, apples, pears, cherries, goosebarries, plums, oranges,
chestnuts, carrots and other foods.


6) Um... did I ask what the rear steering is supposed to accomplish?


Same thing as a skateboard. Have you ever?

sirry, I wasn't realising it was you, Frank, you just din't and wont
get it. It don't need to have practical value, it looks good. This
flexibilty makes it appear more natural, less mechanistic, it leaves
the man as the prime focus rather than a man perched on top of a
machine. I realise you probably not ever understand this pov. I feel
i must try despite the enirmous tumour that blocks your heart
communicating with your mind, a mind hampered by decades of thought
control. A mind which continues to struggle but can not break free
from those limits imposed during childhood. Sometimes, totally
practical everyday bicycles don't make sense, times when practical
everyday bicycles are innapropriate. It might actually be useful but
prejudice denies me from thinking too hard about this (for I might
think it bad) and so I maintain my feelings of the creation which
makes me happy. I'm glad it has been done and don't seek to find
fault with it, just would like to see more.
