I'd go for the Linus Gaston 3 in Philly. Your knees will thank you with a Sturmey-Archer 3 speed hub. Its a classic all round city bike.

The Felt York is a one speed singlespeed/fixie and it doesn't justify the extra $100 premium.

I absolutely love an IGH bike and I have 8 speed Shimano Alfine for my mountainous area. 3 speed is more than enough for Philly.

You will be well served with it.
