So the one main difference about a funnybike and the reason its "funny" is because of the front wheel being a smaller 650c instead of 700.
The cool thing is 650c wheels arent so popular anymore and can be found cheaper than 700 wheels. Thats good for me.
I'm looking at a few on Ebay right now, this Mavic 3G pictured above.
It would look so cool.
