My wife and I were in Sonoma for a couple of nights and planned to hire bikes to cycle over to Moore's Landing restaurant at Cuttings Wharf on the Napa River. I almost rejected the Sonoma Valley Cyclery on the basis of two earlier Trip Advisor member reviews - however the cost and hours of business were better than others so I booked the bikes with them.
The guys in the store were very easy going and friendly. In the light of one of the reviews I insisted on checking and noting any damage to the bikes (only superficial/cosmetic marking). The guy seemed supprised that I bothered and said they were only concerned with real damage.
The bikes were in reasonable condition but only really suitable for casual about town biking. They were quite uncomfortable by the end of our 30 mile round trip. The guy serving us did warn us that a ride of this distance would be pushing it on those bikes!
However we were pleasantly surprised with the casual but friendly and helpful service we received and on that basis would be happy to recommend Sonoma Valley Cyclery to others - but if you plan serious cycling then discuss your needs with them first.
