Fun fact about this pic, the company that rented these bikes had no idea what they were going to be used for. When they found out about this photo shoot, they refused to take the bikes back and/or return the deposit. A happy compromise was worked out where all the seats were removed and paid for, only then did the rental company take the bikes back and return the deposit.
