This is my new commuter. I'd been riding a 17" Trek (I'm 6'2") since my other Trek was stolen and my 15 mile avg. distance was killing my knees. Still very much a work in progress, a new seat is high on my list, also better tires.

My milk crate carries the essentials plus lots of room for whatever else I need to transport.
