My question has nothing to do with passing emissions, that is not required in Arizona for a motorized bicycle. What I am referring to is that it is my understanding that unless the motors are EPA complaint (phase 2, tier 2) they are banned from import into the USA. The ban started in January, 2006. Aren't your motors under that ban? I am NOT accusing you of doing anything illegal or the such, I just want to know EXACTLY what is out there, what it is and how it got here. I may want to purchase one or more kits from you. Thanks for your help, Steve.
