I had such a wonderful experience with Théodore at Dolce Via! this was the only bike shop in Paris that offers the service of renting a bike in Paris and then dropping it off in London, and they will pick it up for you! He was so responsive in his communication and helping us plan our trip biking from Paris to London, letting me text him on WhatsApp with all of my questions leading up to the trip! We rented really high-quality gravel bikes, and we had an awesome tour. I highly recommend this bike shop.
