We decided to cycle across the Golden Gate Bridge and came upon this company by chance. We had been recommended to use one of their competitors but this was the shop we arrived at first and thought we would use them - what difference would it make? Well I can tell you, we now know the competitors are so friendly and helpful, which is the complete opposite of these guys.
The men who served us were so rude and they made you feel like you were an inconvenience. The bikes were perfectly fine and we had a great day, but don't use this company if you plan to hire a bike in SF.
