please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Boygoesfast on ebay sells the round pucks, I have two engines that use them also, if I were at home on computer I'd post a li k for you but my phone and ebay dont jive on links... only dang sight I cant copy the link on for some reason....
But yeah just do a search for motorized bicycle parts on ebay and when you find boygoesfast search his parts link and you will find them.
I can make the round ones out of super heavy duty material but because the material is so hard on tooling I would have to charge about $23 for a set of 15 pucks, but I could make you a set if you were willing to pay that much or for about half that you can get some stock type from boygoesfast.
Hope this helps ya out
