Here's my contribution to the utility bike thread. This is the second Xtracycle I've built. The first one didn't work out due to some seating position issues, so this is build 2.0. It is actually based on the Xtracycle Radish, but is completely customized. I bought the front half of a Radish frame to use with the FreeRadical which I already owned.
