We did the 9:30 am bike tour of Montreal with CA Roule and had agreat time! Michelin was a great tour guide. And as others have mentioned, after the tour, you can keep the bikes until they close, and they'll give you a bike lock, so you can ride all around Montreal, and stop at places, etc. After tour we kept the bikes and rode to the Atwater Market and had lunch, then rode the Lachine canal out and then came back by the rapids. It was great!
