IMO the Rohloff gear hub is best installed in a frame specifically designed for it. Otherwise various additional parts and work arounds are required for a satisfactory installation.

The Civia Hyland frame is available separately and has Rohloff intended bolt on dropouts available. I have the complete Civia Hyland Rohloff and like it a lot. Civia also offers either CF or steel forks for the Hyland frame, take your pick. It is a large tube diameter aluminum frame.

Thorn Cycles of England does a number of Rohloff specific frames that use eccentric bottom bracket chain adjustment. All their frames are steel if you prefer that.

Neither may meet your cheap & ugly requirement. Why do you want to put a high end hub into a cheap and ugly frame?

Any frame with non Rohloff specific design dropouts requires either the long torque arm arrangement or use of a Rohloff speedbone for hub anti rotation against torque forces. All well covered in the Rohloff hub manual. Standard vertical dropouts also require a chain tensioner.

BTW I also have the Swobo Dixon and the dropouts are fine for a bolt in gear hub such as the stock iMotion9 hub. They are rear opening dropouts as also used on most FG and other gear hub bikes, not sliding or adkustable dropouts. The only kludgy item is that the disc caliper mount does not move with the wheel when adjusting chain tension so occasional caliper position adjustment is required.
