Right now it's just a concept. I used a TALL Schwinn Traveler for the virtual "mockup" but I won't be cutting the Traveler up. I do have a similar Nishiki, but it's not here and I'm afraid it's not steel (I can't weld it if it's not steel) I do have a couple other frames and anything goes here except the Traveler... So here's the idea. Cut up a TALL diamond frame and reposition the tubes as a LONG BMX seems pretty straight forward to me, plus stretch the chain stays... But it's always about the details... So yeah 20" wheels and fork, I'm pretty sure I have a set of old mongoose mags. I'm hoping I can source some BMX parts to fill out the build. Carl.
