Mike's Bikes has a great selection of bicycles for the family. Whether you want a road bike, dirt bike, or hybrid, they will have something for you. If they don't have a bike for you, they will special order one at no extra charge.
I bought my Specialized Expedition Sport (a hybrid) at Mike's Bikes on their recommendation. It is the best bike I've ever ridden. They also included a free tune up and fitted my bike with accessories that I purchased at the time I bought it.
They let you test ride the bike outside the store as well, to make sure that you like the bike you've selected. They also make sure that the bike fits you properly, and they make adjustments to the bike if needed.
I highly recommend Mike's Bikes for your cycling needs. They have brands like Specialized, Gary Fisher, Trek, and Bianchi.
