I bought my pocketbike off ebay and had no trouble, but it was actually the second pocketbike I bought, the first one never showed up! :x I ended up getting refunded though, but be careful because there are a lot of even dodgier operators out there who won't refund you. I can recommend this ebay seller as good because he shipped my bike from Melbourne to northern NSW in 3 days. They're called siftech168 and you can see the bikes they've got for auction

But if you're in Melbourne or Sydney you'd probably be better off going to see Carterraceengines or Ozscoot. Out here in the sticks it's probably easier to ebay :roll:
