Does anybody know what's really going on with motorized bicycle kits and the EPA this year? I've noticed that there seems to be a lot less choices of kits now. Zoom Bicycle's has stopped shipping to the USA. They told me it costs too much to get the kits EPA certified and they're not sure if they'll ever be back. That's a shame because they sold the good Flying Horse motors. I seems like Grubee is almost the only game in town for China Girls. I did buy a kit on eBay recently, but now they're gone. Are all the MB retail sellers buying Grubee and that's it now? Does anyone have any idea how much it costs to get EPA certification, and how long that takes? Do you think China Girl kits will soon disappear all together?
