At Saint Jean Industries, our ambition is clear: to support the most innovative projects by drawing on the company’s unique expertise in aluminum processing. A pioneer in the development of complex aluminum parts, SJI is committed to pushing back the frontiers of innovation by collaborating with partners who share the same passion for technical excellence.
It is in this spirit that Saint Jean Industries has collaborated with Beringer to develop an innovative technology, revolutionizing the all-terrain electrically assisted bicycle (VTTAE) sector. This collaboration is nothing new: it began at the end of 2018 with the creation of the world’s lightest aluminum BMX racing crankset, a project that proved SJI’s expertise in this field. Building on this initial success, the two companies recently launched an ambitious new challenge: the design of a seamless aluminum monoblock frame for VTTAEs, once again pushing back the limits of current manufacturing technologies.
The frame, produced using HPCC (High Precision Core Casting) technology, enables the creation of aluminum parts with complex, hollow shapes. This innovation offers a fluid design, better integration of components such as the battery, motor and cables, while maximizing the frame’s rigidity and reliability. What’s more, the absence of welding gives the product a unique carbon-like aesthetic.

VTTAE frame technical specifications
Fluid design: modern aesthetics with no visible welds.
Versatility: suitable for everyday use on a variety of terrains.
Off-road comfort: VTTAE-specific suspension kinematics enhance the experience on all types of trails.
Integration: improved component layout optimizes ergonomics and performance.
Rigidity and reliability: a one-piece structure that offers excellent strength and precision without compromising comfort.
Saint Jean Industries, in partnership with Beringer, has risen to the challenge by designing the first one-piece aluminum frame. This innovative technology can, of course, be adapted to other needs or projects, and plays a major part in pushing back the limits of lightweighting in mobility solutions.
Thanks to this unique technology from Saint Jean Industries, Beringer offers three types of VTTAE models in three different sizes. If you would like to purchase one of the different VTTAE models sold by Beringer, please visit the following address: Bikes (ride-beringer.com).
The frame will be presented during the Mobility Techdays organized by Cara on November 20 and 21.
