Recumbent - Converting 20"in EZ-1 to 26"in rear wheel.

Not sure if anyone has ever done it before, but it seems kind of simple to me.
Instead of waiting for funds to buy a completely new rig, I was thinking of an add-on.
My general idea was to attach a junk, full suspension, mtb rear triangle to the rear dropout of my EZ-1.
This way, I could have the added momentum of a larger wheel diameter, and be able to switch back to original spec's at another time.
How does this sound?

........Hmmmmm

Unless you build a rear drop-out jig you may have problems with the rear not tracking properly. I'd also want to add an increased diameter wheel on the front (22"?) just to even the bike out slightly (so you're not sliding down the seat etc).
I guess the last point is that the bike has been built with certain engineering rules and theroys to maximise comfort, efficentcy and safe handling. I'm not saying it will happen, but there's a chance the composure and performance of your bent could go out the window with such upgrades.

So it's a bad idea in my opinion, but hey I'd love to be proved wrong :)

Well, now that you added all of that, I question my decision.
I originally intended to use one of the swingarm connection holes to link with the rear drop-out.

Hey, they used to build castles and cathedrals that way. I'd be leery of the plan myself, but if you think you can make it work, don't be shy. Progress is never made except when someone is willing to try something that is not already known to work.
