BIXI is Montreal's public bike share system consisting of over 5,000 bikes available at 405 stations across downtown Montreal from April to November. Users can take bikes from any station and return them to any other station. There are membership and casual use fee options, with fees charged based on trip duration. Members receive 45 minutes of riding per trip for free while casual users get 30 minutes free with each 24-hour or 72-hour access pass. Users must agree to terms of use, provide a credit card for security deposit, and are responsible for following bike rules and properly docking bikes after use.
