The German bicycle manufacturer has developed lightweight, carbon fiber bicycles aimed at the European trend in cargo bikes for sustainable urban transportation. The cargo bike’s frame structure includes a lamp housing and Airtag mount as integral components, which are 3D printed from ’s Infinam PA12 nylon. Airtag is an anti-theft device from Apple.

"The challenge was to find the right technology and material for Maniac & Sane's cargo bike components. Considering the requirements: lightweight, functional components that were break-resistant and weather-resistant – and all that in a filigree design, the obvious choice was powder-based 3D printing and the Infinam PA12 material from Evonik," says Markus Albrecht, division manager of additive manufacturing for GmbH, which worked with Maniac & Sane to develop the bikes. The components were printed using selective laser sintering (SLS) technology.
