If you want to get out and see Montreal in a different way, this is a great way to do it. The bike rental rates are super affordable. We originally rented a tandem, then couldn't ride it, took it back and they gave us two single bikes for the same price. In an hour and a half, we rode along the Lachine, over the bridge to Jean-Drapeau and Ile-Ste-Helene and back. A really gorgeous trip because the colours of the leaves were changing. Super relaxing and a good way to get out and see things in the city without falling into the tourist traps in the old town. A must if you're in Montreal visiting from spring to fall (the J-D bike trail isn't open after early November).
