If you plan on riding 50-60 miles a week, you'll be better served by a bike with better components. Buy the best bike you can afford. Stretch your money by looking for 2012 models on sale. If you can wait until 2014 models arrive, you might find 2013 on sale. But that might not be until late August/September.

I think the Escape 2 will serve you well. Head out to the LBS and compare the Escape 1 2 3.
