I recently took over one bike from someone who had a two-bike pledge, the seller wanted to sell one and keep the other. In the end the easiest solution was for me to swap a one-bike pledge from me with the seller's two-bike pledge (and obviously me paying the additional cost for the extra bike to the seller).

Good luck with the sale!
