Bike Pocket

Where is the best place to buy a pocket bike?

Wanted a 49cc pocket bike 47, all i can find are shopping online but I really do not trust online shopping for these things. Someone knows about a shop or an online store really safe to buy one?

one used craigslist. most who buy them are selling mini off after a few months.
