I rented a bike from this company in Golden Gate Park. In the process of renting the bike, I told the guy where I was looking to travel, and he gave me a map and gave me advice how to get there and what to see along the way. However, he didn't tell me that the roads he was advising me to bike down were blocked off for a music festival, which made the bike ride extremely challenging, and ended up with me needing to leave the park in order to bike back to the rental location. On returning the bike, I complained to the guy running the stand, but he claimed not to know. I also complained to their central office, but they claimed that nobody else had complained and blew me off.
This company must know that their main customer base is tourists who don't know the city or its festivals. If they're going to rent bikes to tourists, and give them advice on where to bike, I think that the company has a moral duty to know what's going in on the park and give correct advice. Their failure to do so, or even acknowledge that the made a mistake, leaves me feeling scammed. I recommend avoiding this company.
