MBBO Offshore Account

I'm in with this unknown frame. No serial # that I could find. Maybe a Bratz bike or similar offshore frame.

I found the bars and seat at a swap meet several years ago, just been sitting around waiting for a frame.
The chainring/guard is kinda neat, I'll probably try to get it straightened out and reuse it.

I plan to use these Schwinn exerciser rims.

I'll be using this Shimano coaster. Haven't looked for a front hub yet.

And some more exerciser parts.

A little more teardown. Exerciser wheels, had to get rid of the solid tires:

Voila!

Seat post was a little stuck, and the pedals were a little grumpy but were no match for the Kroil.

I don't have a suitable 20" fork. I do have this NOS 24" fork.

might as well see how the exerciser covers look

Cool project! If you have a way to bend tubing you might be able to sweep those fork legs forward a bit for a custom chopper look.

In that neighborhood. Bend to suit!

Got the old seat post clamp off that had been spot welded to the seat post. I have a nice shiny one to replace it.

I think I will try this fork. After checking, I didn't have a suitable stem to fit the other fork. I have a nice shiny stem that came from a Raleigh exercise bike. I'll replace the bolt with something less dorky.

I was going to use a Shimano coaster but remembered I had one of these.

This has a 36 hole shell but I have a 28 hole shell coming.
Will need to spread the frame a bit. And come up with a shifter.

Dreigang means 3 speed hub.

Dreigangschaltung...??? 3 speed hub switch?

Fit up my Sachs hub. Was expecting to need to spread the frame, but happily it dropped in. Torpedo Model 515 Dreigang

Started a bit of sanding. Frame will be neither green nor gold. It's all coming off pretty easy. Had to smooth out some warts on the rh chain stay with a file. Looks pretty good now.

hub = Nabe
Dreigang means just 3-speed
Dreigangschaltung = 3-speed gearshift (could mean derailleur also)
hub switch (or gear hub) = Nabenschaltung
So, pretty correct!

My German is a bit rusty, haven't spoken it for about 35 years. But it's amazing how some things can pop back in your head.
Glad I was close, I would have felt like a dufus.
