I’ve been wanting to get a Schwinn and do the whole monty conversion with
the miyata seat. I was carrying around my miyata at school for a vaudville
show we were putting on and a friend of mine was talking about how he
tried to unicycle, but got easily frustrated and now he has this uni
laying around in his garage. I went to check it out and it was an old 24"
schwinn. I now have it, but I want to put the 20" monty tire on a schwinn.
So my obvious question is can I put the 20" tire on the frame that
currently has a 24" tire.
It is possible, although it’s also expansive. You will have to buy the new
monty rim, and tire, spokes, probably want new crank arms, pedals, and
maybe a new hub. I am not sure how to get the fork blades off, but there
is a tool out there that can do it. Unicycle source has an option to get
the monty wheel into the schwinn frame. This is the page they have for it: <http://www.unicyclesource.com/Monty_Trials_Wheelsets123427.html>. If you
want a miyata seat on this schwinn you might want to do some custom
cutting and welding, or have somebody do it. or you can just get a carbon
fiber seat and have it drilled for the schwinn seat bracket.
