11 useless posts and all that needed to be said that, 5'4 person does not fit on a bike with a 57cm top tube, end of story.

A guy who is 5'10 would be riding a top tube of around 53cm for a direct comparison. Everyone is different but 57 for someone 5'4 is really ****ing out there.

Get a smaller bike, or go to a real bike shop and get fitted properly.
