I may have good news for you guys. In ohio there is a business that sells mopeds. They also have a motored bicycle that is gas powered. Looks like what you guys ride. I dont know if he still has any for sure, but I think he does. You guys being his customers will hopefully keep that ball rolling. I checked the ohio digest and found that his motor kit is on the approved list "Wildfire 26". Anyway go to wildfiremotors.com. His business is located in Ohio. You could sell your old kits and buy his to put on your bikes.

Hope I was of help getting you guys legal.

p.s- his complete bike is just a touch over $500 dollars-includes disc brakes and small generator for lights.
