Where is the downtube on a bike

Something that sounds simple on paper, but when you have to make a cut-out in the downtube — which has a massive influence on the stiffness of the bike — to integrate a motor and battery pack, it becomes a bit more of a challenge.

Never, people to back down from a challenge, our carbon engineers went to work. As we expected, the necessary cut-out for integration of the Fazua motor and battery module compromised the structural stiffness of the downtube with conventional wall thicknesses under torsional loads. To compensate that, increasing wall thickness was the first step in fine-tuning the downtube design. The demand on having a cut-out in the frame's downtube let us rethink carbon frame development. The additional integration of the Fazua motor led to a much more complex lay-up.

FEM and CT Scanning of the frame showed us where we had to strengthen the construction and where was room for weight reductions. Only CT Scans allows us to really dive into the heart of a constructed bike and guarantees us the best quality you can get.

It describes our process to design our carbon frame structures in such a way that the structures are optimized to the riding that we want to bring to a specific model.

However cooking spray also makes the tubes slippery to grab in the event of an urgent off-bike moment. The Swiss Cycling Federation may be the only ones who know just how effective this hack is. News , Racing , Tech , Tech news.
