As far as currently functional i have a touring bike, a road bike, and a mountain bike.
I have a cruiser and another road bike in the process of being refinished, and another mountain bike in the queue.
The touring serves as my commuter, the road bike is for exercise, and the cruiser is/was for funsies (not currently in use because it's in pieces and its components are in dozens of zip lock bags). Not sure what to do with the mountain bike, as i prefer to hike the trails...
So perhaps i do own too many bicycles.... but i doubt anyone can pry them out of my fingers. :.)
