I put an Ez-Start lawnmower plug on it (works) and put a 2.25" Bell Streamliner cruiser tire on it.

Bell Streamliner Cruiser Bike Tire 26" x 2.25 - eBay (item 140460888818 end time Feb-28-11 17:30:29 PST)
I like the tire, but it needs a big clearance, not with fenders! And use a thorn proof tube 2" or bigger.
