While not as cheap, I've seen really nice bars on an Electra mixte.

They sell them at: https://www.electrabike.com/store/

You have to look to the "Ticino Parts Collection", then at the bars. You can also look at the Ticino bikes for a better idea of the look.

Just because I'm a slow learner, do I understand that the VO bars WILL fit in that stem, but just didn't fit in your frame? (Sorry, I am a bit slow...) If they do, that may be my best combo for this Nishiki.

Thanks.
