"Located just across from the Fairmont Château Laurier hotel, RentABike offers bikes for rent by the hour, the day or even by the week. Each bike comes with a bike lock, which makes it easy for you to stop at interesting spots along your way. Escape Bicycle Tours and Rentals, located at 65 Sparks Street, also offers daily bicycle rentals with similar inclusions. Both companies, which are open until the end of October, offer guided tours as well."
