Recently purchased this bike from a guy off of Facebook Marketplace. He knew nothing about the bike and I haven’t had any luck identifying it. I have researched and looked through tons of pictures on the internet and social media’s with no luck. I have only seen one other bike like this on Instagram, no details on that bike either. There are two sets of numbers on the left side of the steering neck on a tag: “1258047” and “599MX” below the first set of numbers. Can anyone help me out and identify it? Thanks in advance.
