Just a suggestion:
Go to Goodwill or somewhere similar and buy a used childs bicycle. Be sure to give them a little extra to support their cause. I bought a childs bike at a local Goodwill for $10...and gave them an extra 10, so I had 20 bucks in the bike. Strip the front fork off the bike, that's really all you're gonna need. Put the rest of the bike into the metal recycle program somewhere. Get a small piece of aluminum or steel, about 4" by 3" and drill holes in it for 2 U bolts to fit through on each side of the hole you'll drill for the fork tube to fit through. Use wing nuts for easy on-off. Drill a hole through the top of the fork tube about 1 1/2" to 2" down and insert a boilt/nut so the metal block wont fall down any further. Then just clamp the wheel onto the rear bar of the frame or rear deck, grab the toon by the front footpegs and roll it around just like a wheelbarrow. It worked for me like a charm, and I had a total of about $25 invested in it.

Good luck!
