Howdy. A family friend who's a single Mom is looking to get small dirt bikes for her two boys, 9 and 10 years old. She doesn't have a lot of money, and asked me about some of the Chinese clone bikes such as the ones sold by Powersportsmax for 400-500 bucks. I don't know anything about them. Are they worth the money? Or are they just going to be more trouble then they're worth? Any recommendations? I appreciate the help.
