My "office" is no doubt a lot different than most other peoples, but most of my bikes hang in my studio. It is nice to have your favorites where you can look up and see them while working.
This is an old photo, need to update it as most of those bikes have changed a lot in the last two years. The studio is still a hazardous mess.
