I keep my best bike in the bedroom, its the first thing I see in the morning and the last on a night, I could keep it downstairs inside in my shed built onto side of the house but too frightened the other half scratches it going into the deep freezes etc like she has done already. I may move it down one day to see how it goes again, but I am planning on covering the frame with pipe lagging if it will fit or just bubble wrap.
Out on the road if I am alone, I never get off it.
