This bit of common sense is quite refreshing.
It is a good idea to ride with brakes, at least until you become experienced, and even then it is highly recomended. If you have a local bike co-op or a good local bike shop, go there and buy the parts at least, though you will probably be buying your bike there as well as you're interested in a bianchi, and have them help you mount the brake. Also, ride the bike some and make sure you get your cog well fixed, as it probably wont be tight enough when you get it. This will prevent slipping and keep your hubs intact, un-mangled. Finally if you get a pista, gear down. They come stock with a 48/16 which is QUITE the stiff gear, maybe a 42/16 or 48/19 would be a nice gear to learn on, it will lend itself to speed control and spin abilities as well as be a bit easier on the knees.

Oh, and enjoy the bike. It's a sin to not
