Tzmann — Menomic
A body-fitted 3D-printed carbon ebike concept taken from vision to fully rideable prototype.
Andre Gotzmann, founder of Tzmann, had a genuinely original idea: an ebike where the carbon frame is 3D-printed to match each rider's exact body measurements. The technology existed in theory. What didn't exist was a clear path from that vision to a physical object that could be ridden and validated. ZÆT translated the founding vision into engineering reality — from concept to a fully ride-tested prototype.
The Menomic was built into a fully ride-tested physical prototype — validating both the 3D-printing production approach and the underlying structural engineering. A concept that could have remained a render became a product with a verified manufacturing path.
