I'm sure Pat will answer soon, but I think the 200 frames are the same tubing, but the frame has a longer wheelbase. I could be wrong.

Thanks for the comments, guys!
The frames all share the same shape from the seat post tube forward. Built in the same frame jig and all use the same shape gas tank.

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.

Here is a direct comparisome of the frames.

Always liked this picture. Major component groups for a Bonneville Flyer.

These are something I have been working on for the pedal only bikes and the electric crowd who want battery storage. Panel tanks.

Thanks Pat. It sure helps anyone to match up the build they want to the frame.

Steve.

Every time I get to spend some time working on my bike and do even the most minor fab and it comes out just as i wanted i just think aloud about how great it would be to do that as a living and then i also remind myself that if i were i would get frustrated and need a vacation every month. How did you make this happen? Can we all work for you? i can live in the shop and only require one meal every day and a half and beer.

I like new frame better! The straight seat stays have a more authentic “antique/retro” look to them.

Hi Velo,
A couple guys have made electric bikes already and I did get good feedback, like the tank needs to be wider. Their batteries fit but they wanted to use a larger batter pack. As for the controller, not sure if it fit the toolbox, but the plan is that is where it would go.

! TASTY ! I've been vacelating on a electric build! What would be really cool is instead of a door port for battery access; using duz fasteners for full access to the entire compartment.
