How's that thing geared? Looks like a LOT of weight to be peddling for an extended period of time.

Air suspension on a bike? sounds like fun!

Looks fun, but it doesn't look like it can carve through turns, but it's not easy to design a 4-wheeler with independant suspension that can carve like a bicycle.
Here's a couple of similar oldies from the gizmag archives: http://www.gizmag.com/go/5541/ http://www.gizmag.com/the-carvx-four-wheeled-carving-recumbent-bike/10077/

First, Skip the Off Road BS, much past age thirty muscle mass decline makes a toy like this way too tiresome, fun but way too tired fast! So, lose one of the rear wheels, shift to a Slanted Recumbent position, add TWO 250 watt hub motors to 26 inch front wheels, add some light fairings, and you get a useful, fun, Pedal Elec vehicle that can kick ass on the roads in around the town commuting and cruising!

@StWils - Way to design a 100 percent different product for yourself! That sounds even more unnecessary than this Athos, only at least this thing is fun to check out. Just get a trendy e-bike, if that's what you want.

Let's see, can't pump the berms, suspension bob, probably heavier than a downhill bike, two more shocks to blow seals off, can't distribute brake force between left and right wheels, more than 2x more rolling resistance, 2x more wheels to true, a ton more moving parts, can't throw on the roof rack, can wheelie easier but won't earn any respect for it, and bump-induced steering...
On the plus, throw some ATV tires on it and call it a sand quad for towing surf boards, kayaks, and life guard equipment on the beach could be a useful role.

OK so this is not for serious off road bike trails and may get tiresome but think a bit wider. I am sure there are some people with disabilities that would just love one of these to tool around something a but rougher than the local park or footpath. Thier stamina is often remarkable when they can get to do something close to fully abled people.

You can't ride this in most states on the road as legally it's a car.
The other detail is why? downhill fast maybe but up hill just isn't going to fly because is excess weight.
