Bike Rental was very easy to use without much problems. At first I stumbled a little bit not knowing any French. I would recommend to install the app you get the first ride free as a promo. Once I got over the first time user speed bump it was easy sailing and I used this more then Uber to get around Montreal while I was there. There are many docks at good locations close to main attractions and things to do. This bikes being used many times per day by many people inevitably will have some problems (rough gear shifts or dirty) but the problems are sparce.
