Last spring, I rode on a BIXI bike in Montreal, QC. I could not get off that bike fast enough – it was so heavy, clumsy, slow, ugly. I immediately paid to ride a real bike. Fast forward several months and I am in Barcelona. Their bike share bikes are for residents only – no tourists allowed, because it will harm the bike rental business. The choice of bikes for a bike sharing program probably matters; and, after riding the Montreal bikes and seeing the Barcelona bikes in action, I highly prefer the Barcelona bikes.
