Is there a market for a push/pull handcycle?

Dear handcycle users,

Please let me know if the handcycle shown here is cool and useful, or just lame and stupid:

Drive power is applied in both push (bench press) and pull (lat pull) directions. This is my first market research to decide whether to "push forward" with development of this idea into something lighter and cooler, possibly a removable wheelchair attachment version, a 2-wheel version, and a version with a sliding seat to incorporate the leg extension component of rowing as well. Though the battering ram on the bow is cool, that'll eventually be covered in a fairing. Technically, this contraption is a rack-and-pinion driven linear handcycle, patent pending.

Thank you.

Probably a very small one.. so figure out how it can break down to be shipped internationally, one at a time to a lot of countries.

might have to be cheap for the countries with live landmines to continue amputee survivor market .

Fietsbob, thank you very much for the insight. I'm curious about 2 potential markets: 1) those with a lower body disability as you said, and 2) fitness enthusiasts who want an upper body workout during their commute. Your advice about making it compact for shipping abroad is quite useful for me to consider too.

fietsbob makes a very good point re: being cheap for the landmine survivors. Your best bet might well to be to pursue 2 different avenues with a shared drivetrain, a high-end version for the western world and a much simpler one for the third world. Both will have to be very reliable mechanically. Think about a failure for a paraplegic far from home, maybe in the woods. Could end up with loss of life. True story I heard from the wheelchair user. He drove the Oregon Coast to wheel up a trail into the Coast Range. Got a late start so people were hiking out as he was wheeling in. Got to his far point and turned around. Now downhill. He lost it on a corner, went off and slid/tumbled down a 50' embankment to the stream below. Landed on a fallen tree only 20' down. Now he was a very experience "hiker" and he had strapped his chair to his ankle for just such an occurrence. With great difficulty, he inched his way up the embankment dragging his chair. Got back to the trail. Now it was dusk. Got back to his car in total darkness.

Wheelchair users will do this and other crazy things with your device because they can. If it isn't reliable, this will come back to haunt you.

The flipside is that a simpler but just as reliable device for the third world could be life changers for a lot of people in the third world where there are millions of landmines claiming victims every day.

Ben, thank you much. I hadn't realized the limits wheelchair users might push with a handcycle, but it makes sense if it could enable mobility to such an extent. Reliability is indeed paramount in that case.
