I have the same questions you do. So far I learned that if you can, hang the bike up on hooks. That this will keep the tires in the best condition if you are not going to ride for a while. Also, the cold in your basement won't harm the bike, except if you bring it into a warm house-- it can result in condensation on the bike, which is not good. I wouldn't imagine you'd be bringing it up until the warm weather kicks in again. My bike is down my basement and covered by a sheet to keep the dust from gathering on it. I remember reading somewhere to keep it away from refrigerators and furnaces. I am not sure why, but I do have mine off in another area. I wasn't sure what else to do either. I'll watch your post to see how others answer.
