hi there, im currently researching into product i will possibly be manufacturing for my product design A level. I have been told that damage can occur to bicycles if they are stored in a garage because of the cold weather. what truth is there in this????

I have stored bikes in the garage since I was a boy many decades ago.
It gets very cold in Saskatchewan. It can be -30 to -40 for weeks and its winter for 6 months sometimes.
I have never seen a bike damaged from the cold.
