OFF:
The main problem in Hungary is this: these bikes are unique -- hence the "Nay, I don't wanna do this and that part, haven't did or tried to do it before, what if something goes wrong, I'll be the one to blame, nooo way I do anything I haven't used to..." mentallity of experts.
It's not like collecting stamps: this is not an everyday hobby. I guess people regarding us as alchemists were at medieval times -- obscure people doin' sinister things in garages... This summer I was at a bike shop looking for rear hubs. When I told the owner what I'm planning to do out of it he questioned me: "Why on earth do you do this? Buy a scooter that runs better and have a bike for leisure!". I guess, enugh said.
We don't have that bike culture you have in the States. Up to the nineties, we used to buy the bike available at the shop, ride it, if something fails: go to the service shop. After the nineties: buy the bike at the Honda-Yamaha-Suzuki, etc. dealer, ride it, if something fails: call the dealer who manages the servicing. We got used to tinker on the bikes, buy accessories for them, but we don't have that bike modding and custom culture you have out there -- think about it: when you customized Hot Rods in the fifties, we couldn't afford a motorcycle even and feared from a communist dictature.

Thank you guys for the sources, checked them, but the Nirve, Johnny Loco and Electra bikes are too expensive to chop 'em up to make a frame.
