I have rented bikes all over the world and so far Dandyhorse is the best! They have great rates and amazing service. My girlfriend and I were looking for quality bikes that were well maintained and we found them! Dandyhorse offers custom tailored bikes made for riding San Francisco’s hilly terrain. Dandyhorse doesn’t stop there, they also provided instructions and a map that they go over step by step of the best stops and things to see. They even routed out a trail through the city for us so that we would not bike any hills! Very informative and very accommodating! We will certainly be back and would certainly recommend this place first to friends and family.
