Here's another thought. - regarding location. If your focus is repairs and accessories, location should be really low on your list. You're a service provider not a salesman, how many auto repair shops do you see in town? Keep your costs down while you build a reputation as a 'bike-fixer'. You want people to bring their problems to you so you can dazzle them with your magic wrenches. They can buy their steeds somewhere else, but you'll being the independent mechanic who knows how to fix a bike. You'll still be poor, but what the hell they'll make a movie after you.
