Jeff Crawford 5 Our family has 6 bikes, all of which we keep outside. All of them have covers. When storing bikes outside, it gets windy between tall buildings, and bike covers get threaded easily.This bike cover is by far the best one we have had so far. The material is nice and thick, and it is well fitted to my bike. It's good quality.I would get the one with the black stripe on top. It makes it easier to determine the top versus the bottom when putting it on your bike.I am about to order another one.
