We were disappointed with the condition of the bikes. All three had some issues. One squeeked the entire time, all three were difficult or not able to change gears at all. The person behind the counter was not very friendly at first. He loosened up slightly after awhile. The only positive thing to mention was his last minute bit of info. regarding the option to drop off the bikes in Sausalito for a one way trip, after our surprise that they close at 6:45pm. This incurs and $12 per bike fee, but well worth avoiding the headache of hauling the bikes back on the ferry. Riding the backs back to our initial starting point was not an option for us. They say it's mostly downhill on certain parts, but this is not a trip for the occasional biker. Dress warm, it's very windy and cold on the bridge. There was also construction on the biker side, so that left very little room for two way traffic with some crazy speed racer bikers coming through. The signs say 15 miles per hour, but that did not hold for some. We reserved and paid online so we were unable to see the bikes till we picked them up. I would recommend paying the extra on site so you are able to see what you are paying for. I'm sure not all rental companys are the same. This is only in reference to Bike & View on Lombard St.
