If David wants to buy a bike without paying interests on it, and has all the money that's necessary to buy said bike, then his best options are the following:

He could access his funds directly by using a debit card to his account, or use a credit card and then pay the full amount once the bill comes.

If he decides to use a credit card only and not pay in full once the bill comes, he would need to pay interests on it over the course of an extended time period. This would go against his personal interests.

Therefore, your best answer is Use a debit card, or use a credit card and pay the balance in full when the bill arrives.
