We work with professional bike rental companies who offer quality equipment, regularly renewed and revised between each customer. Problems are therefore rare, but can happen. You must at least know how to replace a bicycle chain and repair a puncture. A puncture kit is given at the same time as your bike. However, in the event of a problem, we ask that you call us so that we can find a solution as quickly as possible and you can continue on your way peacefully. Note that the professional may be required to come to help you provided that the problem does not occur on your personal bike. Likewise, the customer undertakes to cover the troubleshooting and repair costs linked to inappropriate use or handling of the equipment.
