Incorrect. Its not like a Segway at all. Provided the centre of gravity is below the effective centre of rotation it's inherently stable, and the canted wheels actually raise the centre of rotation which makes it more stable than if they were vertical.

@winzurf: true, but as the centre of gravity is not much lower than the wheel axis, braking hard would make the passenger compartment to roll over forwards.
I remember both seeing this happen in a old video of a concept vehicle like this one (on some discovery program) and as a kid i had a similar toy.
I believe the segway counters this by tilting backwards, but if you search youtube, you can see examples of what happens if a segway wheel is stopped abruptly for instance by hutting a bump. It looks painful.

Transparent canopy = greenhouse. Hope it's air conditioned. And why, with all that transparency, are there two big non-transparent blind spots left and right?

Isn't that 'large chrome brake lever' actually a folding armrest, designed to allow access through the door?
4th April, 2012 @ 9:02 a.m. (California Time)
I have no idea. That is a damn good question. That calls for some design reworking before it should even be considered viable. They ought to do something about the extreme amount of sun that would come in (i.e. a radially opening window system on each door or blocking the light coming in the top out).

Sanu K R, you stole that idea from Mr. Garrett on South Park!

What's it propelled by, telekinesis? Ah...good wishes, that must be it. Otherwise I see no room for batteries, engines, fuel tanks, fuel cells.....you know...propulsion?
And what about rainy days? How does one continue to see?

This is not particularly original - there have been a heap of "inventors" or "creators" of these things over the years...
This is just this guys version of the same general theme......
These ARE really great machines - provided ALL of your emergency braking distances are substantial.....
4th April, 2012 @ 4:15 p.m. (California Time)
old concept but new in a new style...
4th April, 2012 @ 5:33 p.m. (California Time)
Hardly a new concept. There have been many ideas like this.
4th April, 2012 @ 6:21 p.m. (California Time)
The "MOOVIE" by André Costa, from Peugeot Design Contest of 2005 is another example for the same tendency.
However, SPTS ( hey, why not?) was really smart conceived.
Unfortunately, it has not two seats, but until its launch, there is still sufficient time for thinking about this...

The non-transparent spots left and right may be for an element of privacy, however one would hope they are tinted so that the driver can still see out.
There are some transparent coatings that provide visibility in multiple raindrop environments, however the propulsion question is yet to be answered.

Brilliant! Until you have to slam on the brakes then it becomes an out of control ping pong ball.

It needs a two wheel gyroscope to provide forward/backwards stability, the spinning flywheels could also store power from braking by spinning faster.
5th April, 2012 @ 2:09 a.m. (California Time)
As a concept I find it kind a cool, though I to have seen similar designs in the past.
But what most concerns me is people inability to think outside the box here. This is after all a site for new technology.
The rainy days problem could for example maybe be solver by NeverWet, http://www.neverwet.com/
And I can't see any problem with propulsion either. With energy densities probably ten times as high in a not so far of future and super fast charging through supercapacitors, http://www.gizmag.com/graphene-supercapacitor/21925/, that would be well enough for the urban application this type of vehicle would be used for.

I applaud the designer's effort but I see more problems that solutions.
-Storage.....where do you put a bag of groceries?
@ Patrik. Most window coatings last MAYBE ten years and are a nightmare to apply to anything but a flat surface. What do you do when it wears off? It will wear off. RainX the surface every two weeks?

"not much is known" - reason being: this is nothing but a picture..
5th April, 2012 @ 9:35 a.m. (California Time)
Ha ha. I love these. Although these guys have a great old school solution to the breaking problem. http://www.theriotwheel.com/

If that device is all it takes to stop them from riding on top of crowded electrified trains, then good job Sanu.
5th April, 2012 @ 10:21 a.m. (California Time)
They see me rollin'.
5th April, 2012 @ 10:35 a.m. (California Time)
Looks like a great idea for a kids fairground ride... that's what it's supposed to be right?
5th April, 2012 @ 10:55 a.m. (California Time)
Looks like something I saw in a Star Wars movie. But I agree that sudden starts and stops would be an issue with the design as shown.
5th April, 2012 @ 11:08 a.m. (California Time)
Actually, those levers are the propulsion system. The driver cranks them to go.
5th April, 2012 @ 2:13 p.m. (California Time)
I guess anybody with sketchup can get into Gizmag now.
6th April, 2012 @ 8:21 a.m. (California Time)
I've tweaked the design to overcome the issue of rollover when braking - my version just flies through the air. I'm using the exact same method of propulsion.

As a power wheelchair user it reminds me of my wheelchair combined with my sports chair and having a canopy added. Nothing really new here. The wheels could be powered by standard wheelchair motors and two 12 deep recharge batteries. That would give a range of around 70 kms which is about 2/3 of what my chair can go but I'm assuming this would be a little heavier. It would be terrible to use on footpaths as any sports wheelchair user will attest. You generally need great dexterity to use a manual chair on footpaths and it is for that reason that people with full paraplegia like me or the more elderly must use power chairs rather than manual chairs. The braking would be solved by applying the standard braking systems that power wheelchairs use now. That has been around for a long time already and assuming the motors and batteries are right at the bottom of the chair and the seating is low enough the centre of gravity would be such that there wouldn't be the Sedgway type problems with sudden braking.
Still, what's the point? There are very good power wheelchairs around that can go over quite rough terrain such as my chair, have about 100km range on a single charge and cost about $5000 if you get one of the newer ones coming out of China lately. I don't see it as new, innovative or even practical. Stick a raincoat on a wheelchair user and you get the same results.

painfully reminds me of the gyroscope-powered monowheel "It."

How many Syrian Hamsters power it ?.

Must be slow.
Bit large for the sidewalk....
