Consider your environment when designing your store window
It is essential to understand the context in which passerby will become aware of your store. Will people be on foot or will they be in their cars? Think about how much time people have when they stroll, stride, or drive by your store, then design your window displays accordingly.
If passerby rush or drive by your store, use bold and large fonts and use easy to consume copy ('your #1 bike store') as opposed to 'handpicked bicycles that will last long due to their robust materials')
If passerby stroll or stride, you may want to consider using a few neat details that attract attention and make passerby want to get closer to your display in order to take a proper look.
