My wife and I are active bicycle touring addicts and typically take 3-4 major journeys of 2-4 weeks duration every year. In the past we have rented bicycles at several international locations and very often are disappointed with the appropriateness, quality and/or condition of the "touring" bicycles we have been provided with. My last experience resulted in renting a bicycle that suffered 7 broken spokes over the course of 12 days touring. This French bike shop was actually listed through a large Amsterdam based bicycle rental website that offers rental booking at numerous bicycle shops worldwide, but they apparently do nothing to provide any level of quality assurance for the touring bicycles they are representing. And when I posted a negative review about my experience on the rental agency website, the review was deleted due to the objections of the French bicycle shop owner. Obviously this approach results in a list of only positive reviews and provides the prospective rental client with a very biased representation of the rental shop.
One possible solution to this issue would be to create an independent website where reviews of rental experiences could be posted without fear of deletion. Shop owners would be allowed to respond in defense of negative reviews, but the reviews would stand unless it could be proven they were falsely based. I would be interested in hearing from other bicycle touring folks on this subject.
