It really is an unfair comparison. Your friend's fixed gear is going to have lower weight, lower rolling resistance, more efficient transmission and greater frame stiffness than yours.
These are the things you trade off (generally speaking, at equivalent price points) for being able to fold a bike up into a nice small package.
