No test rides without cash in hand. I have a bill of sale that includes a provision to allow the buyer a 30 minute right to return the bike for a refund, provided it is in exactly the same condition as at the time of sale. If they are financing through their bank, meet them there during normal business hours, and have the bank make the cashier's check out to you. I can send you a copy of the bill of sale, which also includes a liability release and disclaimer of all warranties.
