Is storing bikes in an enclosed trailer a good idea? I too am running out of space in my house to store my bikes.  I have three bikes inside my house and my 5 kids bikes are outside in a shed (which is also over crowded).  My idea is to buy a 6X12 enclosed trailer to store our bikes and modify it to also be like a bike shop.  We take our bikes everywhere.  My concern though is keeping the bikes in an environment that is not controlled.  Although they will be completely sealed off from rain, etc., they will still be exposed to varying temperatures and humidity.  Does anyone think storing these bikes in a trailer is a good idea?
So long as the trailer is reasonably weather-tight it shouldn't be a problem.  Since there's nothing in the trailer generating humidity, no significant condensation will occur, and, within reason, temperatures won't hurt bikes.  (The only caveat would be that you maybe should have some vents that can be opened if temps rise above 90F or so, so that temps don't get over about 150F inside.)
