Hi, so this is my first post. So I found a pocket bike on Craigslist for 200 bucks and he claims it goes 30 miles per hour and that it's an X1. Can anyone tell me what bike this is and possibly if it has problems? Or how can i test it for problems, when meeting with the guy? Need to know asap i don't know diddly squat about pocket bikes to tell the truth. First bike so... help please?
