I’ve added a new feature to the Unicycle Home Page, a database of unicycle
models. I took the feature comparison list from the FAQ that Ken Fuchs wrote,
and adapted it into a page where you can look up a unicycle model and see how
the unicycle is built.
Right now there are only three unicycle models listed, the ones I own. I’d
like to add more. I include the list of questions below. If you fill it out
for your unicycle and send it to me I’ll add it to the page. Don’t worry if
you can’t answer all of the questions; I can’t answer them all for my three.
Thanks, Beirne
