Likely by taking a lot of bikes from distributors, factories etc. on promises to pay upon sale, then maybe not following through... I wonder how much of his inventory was on such consignment?
His offer to sell the biz to me for $300k was by phone, not in writing, so I'm reliant upon my somewhat addled memory. I do recall asking how much inventory he had on hand, and his response was along the lines of "a lot more than $300k!"
