If you're looking to ride/rent up north, I have also heard good things about Tenafly. To add another shop to the list, Pedal Montclair 973-746-3200 rented/demoed my friend visiting from Cali a Santa Cruz Bronson. Lou, the owner, had it all set up and dialed in when we arrived and for a great rate. He only rents out a few select models of Santa Cruz line though so the selection may be a bit slim and it's a small shop, but it was a great experience overall if he has a bike that meets your needs.
