This is a floor to ceiling bike storage device that locks into place so there is no worry of bicycles falling. Two bike holding capacity. Bikes hang from the top tubes, although the lower one can rest on the ground and the hanger can help support it up. I did this with my mountain bike, and then had road bike hanging.
No drilling of any kind to install, no damage to your rental!
These retail in stores from 150-250
No damage, all parts included.
