The entire bike rental process was seamless for us at Blazing Saddles. My husband walked in, were greeted by enthusiastic employees, and we were shown the map, got fitted for our bikes and helmets, and we were on our way. The provided bike locks were useful when we stopped for brunch at Sausalito. We were also each given a return ferry ticket that we could use if we wanted to. If we did, they would just add the charge later on. If we didn't, no worries, we just had to give them back the tickets when we returned the bikes. It was a convenient option so that we did not have to stand in line to buy our ferry tickets when we returned to SF.
