I narrowed down to these two bikes myself, and ended up getting the Bad Boy Ultra based on my riding habits and style. Here are a few things to consider:
Internal hubs are maintenance free, but IF they have a problem, you will need professional help that may not be cheap;
The street is an excellent commuter, while the Bad Boy is just a good one. However, the bad boy can become a better commuter with basic upgrades. And a mountain bike with a new set of wheels. And a touring bike.
The street with internal hub will only be available in late october, while you can have your bad boy before the end of the day.
Good luck with your choice. I will have a better review of the Bad Boy as a commuter, with pictures, next weekend.
