So this is a 12.5 " x 3.0 OCC toy bicycle i am stretching it out large enough that i, a six foot tall man, can ride it, then i am putting a motor on it. I found this tiny occ bicycle on Craig's list and knew it would be my next pedal assisted project... It has probably taken a year to get back to it, but I have been going into work a half hour early each day for a week or so, and hope to keep that up til I finish. we will see. The back bone is stretched 27". It has a 16" uptube stretch and I replaced the bottom tube with a 2 x 1" rectangle tube ~25.25" long (btw, thanks to Crazy Horse for the great thread on stretching the 20" bikes, i found it most useful.) i have included a tape measure in many shots, and tried to capture some close ups of the fabrication I did my planning with a graphics program, referencing the tape measure in my imported picture. I feel my planning cut down my fab time.
