I would prefer the LBS to a chain store as the supplier as they can offer good advice to the newcomer. Type- style and price of bike will not matter on your first bike as it will not be your last. All the first bike is there for is to get you riding and to tell you what your second bike will be.

But it will not stop at the bike- Helmet- pump- repair kit are the minimum I would suggest but just get riding initially

Good luck.
