I was wondering if anyone has purchased an 80cc motor, or any, for that matter, from Zoombicycles.com?" Ebay has them, seller is "powerkingshop". I hope its alright to mention the that. They have the best prices I have seen anywhere, $79.95 and $39.95 to ship. I don't see anything about a warranty though, I imagine the majority don't. They do have service though, hopefully you can get parts. Thanks!
