If your a keen cyclist,then don’t think you could run a perfect shop as you would like it yourself. However, if your a good business mind and think long term you should be okay. A sound business plan and cash flow planned out are 2 of the most important items in any business, businesses only fail through lack of cash, not by poor profits.
Keep the cash correct, the creditors happy and treat all your friends as customers, we all know how tight us cyclists are.
If your still interested I wish you the best of luck.
