If you're new to riding, there's much value in choosing a bike that fits well from a shop that offers great service. You'll want to be able to rely on them to adjust your bike as the parts settle in during the first few months. It would also be great if the shop you choose offers regular rides. Not only will that give you some help in learning to ride on the road, but you'll already be going there when something on your bike needs an occasional tweaking.
