Without being able to look (at work), can I ask what era and region is your performance based on? I think I get what you're going for.

If it was '60s mod, I'd go Raleigh or another of the British bikes.

But if you're talking rockabilly, I would go for something 40s or 50s from a US maker like Schwinn. There are some other classic inspired models from current manufacturers who might be of interest too, but if authenticity is what you want this is the place.
