High Wheeler in the High Country

Boulder is a very cycling rich community and if you spend some time here you will see all kinds of cool things. I was out south of town on part of the Morgal Bismark loop and ran into this guy going for a ride on his high wheeler. He had just finished climbing a descent size hill which to me is as impressive as the bike itself. I wonder how it climbs. How do you even get on and off the bike? Just think this guy and his bike on the same roads raced during the Coors Classic.
