Girls love bikes. Girls also love skirts. Unfortunately these two don't usually mix well. The good news is these girls came up with a way to fix that predicament. All you need is a penny (or any coin of your choosing) and a rubber band. As you can see in the video, just place the coin between your legs on one side of the skirt. On the other side of the skirt tie the rubber band around the coin. I hope you enjoy this cycling hack!
