When the spring weather gets here I plan to try and ride my street fox with 26inch MTB rear tire to give it a test ride. Don't have any fat tires in my possession.

Here's a thread by a guy who built a hunting trike and did just what was suggested here - a Timberwolf delta with double freewheel for 2WD: http://forum.atomiczombie.com/showth...ght=timberwolf. He has a thread on a separate non AZ forum with pics, HERE.
