This training includes theoretical and practical contributions, led by a qualified professional mechanic. You will have access to a room equipped with all the necessary equipment to disassemble and reassemble the mechanical elements of your bike. However, it is necessary to bring your own bike, and spare parts are not included in the price. The cycle is accessible to all levels: beginners wishing to learn the basics or cyclists who already have some knowledge, everyone will be able to progress at their own pace.
