Just have the Stuzman wheel shop (Amishmen in Baltic, Ohio) build you a pair of high quality and useable wheels if you can't find a pair of wooden wheels- you will need an odd size- bigger than a wheelbarrow, smaller than a sulky. The decorative wheels are just that- decorative, no steel tire holding them together and will self destruct as soon as you hit the road. If you just want to give this type of machine a try, start out with a bicycle/motorcycle wheel prototype, and get the real wood wheels if you like riding it. There is a group of Draisienne enthusiasts in Britain called the Dandy Chargers- they have a facebook group, show up at various functions in Britain and Europe and would probably be glad to share how they built their machines:
