One of the few advantages of only owning two bikes is that neither one gets neglected too much. Each of my bikes have specific purposes:

1. Fixed gear: Clips and straps. Good for getting my ass around town and to school and back. Also nice for shorter (~20 mile) road rides.

2. Road bike: Clipless pedals. Good for long fast rides. Not good for around town because of the look cleats that are required. Also wouldn't want to leave it chained up somewhere. It's pretty low end as far as road bikes go, but I couldn't replace it right now if it got swiped.
