A BIXI account holder with a valid credit card on file may pay for the expenses of several members. This person is responsible for the account and financial transactions of all their co-members, i.e., the amount of their respective memberships and their usage fees (if applicable). Only the account holder may renew the memberships of their co-members. If a co-member’s bike is lost, the charges will be billed to the account holder’s credit card. On the 20th day of each month, the account holder will receive an account statement detailing the charges of each member for whom the account holder is responsible.
