The Pedal bike frames use the Worksman INB rear triangle, have 110mm hub spacing, and use 1" o.d. .090" wall ERW tube in the front triangle, 5/8" and 3/4" tube in the rear. All engine mounts clamp into the frames. HF79, GC160, and China two stroke engines can be mounted. GC160 mount is still a couple weeks away as I finalize details.
The Sportsman 200 uses 1" o.d. .120" DOM tube in the front triangle, 5/8" and 3/4" rear tubes and 135mm hub spacing. All engine mounts either lugged and brazed or tig welded to the frame. The GX200 series engine is the only option.
The Bonneville is basically identical to a Sportsman 200 in the front triangle with 1" o.d. .120" wall DOM tube and weld in mounts. I cheat the head tube another degree for more rake. Rear triangle is 3/4" .120 all DOM and adds 2" of wheel base. Fatter forks, steering stops and stabilizer mount. Couple other details here and there.
