Cake OSA Flex AP from MARS

The Ösa Flex AP is your Fun & Functional, Modern Transporter!

CAKE’s powerful workbench and towing truck on two wheels, the Ösa is built to carry heavy and bulky loads. Thanks to its agility, huge towing performance, cargo possibilities, and long product life, the Ösa AP is optimized to increase efficiency, lower the running cost, and bring all
equipment needed. The state-of-the-art battery comes with integrated outlets to power electric devices and tools.

Influenced by the workbench, the Ösa AP design builds on a top bar that stretches from the front to the rear underneath the seat. This facilitates
a modular, highly flexible, clamp-on configuration system that serves as the backbone of the Ösa. Users may attach baskets, bags, tools, and more to create over thousand different possible configurations. The bike also features a powerful battery with multiple outlets, meaning
the Ösa doubles as a power station on wheels, enabling the rider to be completely independent, off-the-grid.
