Hold your breath for an onboard-camera MTB descent with Bastien, who has competed in the French MTB championships. We followed our champion for a day and took the opportunity to test our Shapeheart mount under the extreme conditions of mountain biking.
Spoiler: it holds up, proof in the video!
Faced with skeptics, we wanted to take up the challenge once again by collaborating with a professional mountain biker, to demonstrate the reliability of our mounts. MTB with a professional means high-speed descents, rocky terrain, roots, heavy vibrations, tight corners, and sometimes even backflips! Needless to say, our mount went through a real ordeal. And the result? It held strong, and we can't wait to tell you about this adventure
Meeting with Bastien
Bastien has been passionate about mountain biking since he was very young. Used to challenging terrain, he regularly takes part in competitions, including the French Championships. So when he agreed to test our Shapeheart magnetic mount, we knew the test would be merciless… And that was exactly what we needed to prove that our mount is up to the most extreme challenges.
A test on varied terrain
For this test, Bastien took us to his training ground: heading to Fontainebleau, on steep trails scattered with roots and rocks, with sharp descents. As shown in the video, our mount held firm! Our magnet, capable of supporting up to 10 kg (50 times the weight of a phone), keeps the phone firmly in place even at 70 km/h on a full descent. And for the more cautious, a safety cord ensures maximum peace of mind, even in the toughest conditions.
Solid performance
Throughout the day, we chained descents and obstacles and unsurprisingly, the Shapeheart magnetic Sleeve didn't budge. Bastien even told us he didn't expect such stability, even during the biggest jumps. In Bastien's case, in addition to protecting from rain, the Sleeve also has the advantage of protecting from mud. What more could you ask for?
Bastien's verdict
After several hours of intense downhill riding, Bastien told us he was won over by our magnetic mount. He particularly appreciated the ease with which he could remove and place his phone — handy for taking photos, accessing his GPS, and training settings. For him, it's a bike accessory he could recommend to all MTB enthusiasts or cycling fans in general.
Why choose Shapeheart
This day allowed us to once again validate the quality and reliability of our phone mounts, even in extreme conditions. Whether you're an urban cyclist, a mountain biking enthusiast, or a pro, our Shapeheart mount goes everywhere with you, never failing. Tested and approved by a champion: you can say it holds!
