honestly the only way to know what the best bike will be for you and your commute is you. Your price range is more than adequate, I would use the remaining cash for add on's, such as racks, panniers, baskets, locks, etc.. You need to go to your local brick and mortar and ride some bikes, lift them up, and see whats be best for you. Hal Grades Your Bike Locking 2014 (Part IV) on Vimeo ...great advice.
