In seattle there is Gregg's Cycle which has a location in greenlake and in Bellevue. There is Bicycles West in Tukwilla. Up north theres are two locations of Bicycle Centres, one in Silver Lake (Mill creek area) and the other in Everett. All these are good shops. I bought my bike from Bicycle Centers most recently and my first bike from Greggs. Greggs is the most professiional shop, so I would recomend going there first.
