I've had a TS50 for a few years. Fun little bike. The stator went out, so it's been sitting for a while. The 50 looks like someone took a shrink ray to a regular size bike and reduced it to 2/3 size. It went 45 or so, not too fast, but is street legal and here in AZ doesn't require emissions or a motorcycle endorsement). For $150 you can likely part it out if it's a lemon and get your money back.
