Keep a new bike new!
1. Store it. Parking your bike inside is the easiest way to keep it looking like
new. Nothing's worse for it than constant exposure to the elements. In coastal
areas the air is so caustic it will actually eat the metal rubber. If you're
strapped for room, purchase a plastic-coated bike hook at any shop and screw it into a
stud in a corner big enough for the bike to hang vertically.
Or you can suspend it upside down by the wheels from two hooks in the ceiling. Be
creative (or even decorative). Maybe there's enough space in a closet, over a
stairwell, or over your bed. If you can't put hooks in your ceiling or walls,
consider a free-standing rack that'll hold your bike up and out of the way.
