WE MAKE YOUR IDEAL MOUNTAIN TANDEM BIKE!
Our brand has vast experience in the sector and many years of development dedicated to mountain tandem bikes. This has allowed us to refine our designs and technology, ensuring that our products meet the highest standards of quality and performance.
Enduro tandem bikes are ideal for mountain tours on tracks, trails and demanding terrain. The rear suspension absorbs shocks and vibrations effectively, providing more comfort and stability during the ride, especially for the second rider. In addition, by keeping the wheels in constant contact with the ground, traction is maximized and control is improved, making it possible to overcome difficult roads with greater ease and safety.
Our commitment to innovation and constant improvement drives us to remain leaders in the mountain tandem market. With high-quality components and a robust construction, we guarantee the durability and resistance needed to enjoy mountain adventures for years.
“The latest creation is the Campmajó Bikes EnDuo tandem, a model that already has a long evolution behind it and which, custom-made in Spain, is presented as the best MTB tandem you can find”
