    Bike Share Toronto is the city's official bike share program, designed to give locals and visitors a fun, affordable and convenient alternative to walking, taxis, buses and the subway. There are 200 Bike Share Toronto stations and 2,000 bikes across the city, making Bike Share the most accessible way to get around and explore.

How it works

    Become an Annual Member or buy a day Pass to access the system.

    Find an available bike nearby, and get a ride code or use your member key to unlock it.

    Take as many short rides as you want while your pass or membership is active.

    Return your bike lo any station, and wait for the green light on the dock(停靠点)to make sure it's locked.

    Choose a plan

    For visitors

    Day Pass: $7.Unlimited 30-minute rides in a 24-hour period.

    3-Day Pass: $15.Unlimited 30-minute rides in a 72-hour period.

    For locals

    Monthly Pass: $25.Unlimited 30-minute rides for a month.

    Annual Membership: $90.Unlimited 30-minute rides for a whole year. The Annual Membership is the best deal for locals of Toronto and other frequent riders.

    The first 30 minutes of each ride is included with the membership or pass price. Avoid extra fees by dropping off your bike every 30 minutes at any other station. If you keep a bike out for longer than 30 minutes at a time, you will be charged an extra $1.50 for the first 30 minutes over, $4 for the next 30 minutes, and $7 for each additional 30 minutes after that.
