I don't think it implies anything, its just xtracycle showing the various bikes the freeradical is compatible with. That bike in particular is a Dahon Cadenza 8, which is a pretty nice bike.
There has been the odd day where I wanted to hang out with people who use cars, but the xtracycle won't fit inside the average small car without extreme measures. Taking some length off the front end would be a nice option, as long as the Cadenza had the moxie to still serve as a cargo bike - one thing I would be concerned about, as Dahon's bikes have pretty low maximum weight limits.
