The Kalk OR, the flagship product of the Swedish e-motorcycle manufacturer Cake, has been included in the Petersen Automotive Museum’s permanent collection. In April 2019, the museum first featured the Kalk OR in an exhibition titled “Electric Revolution.” Cake was founded in 2016 as a “high-performance zero-emission off-road motorcycle brand” by the founder of POC Sport, Stefan Ytterborn, and has since received many awards, including an Outdoor Retailer Innovation Award, an Ispo Award, a German Design Award, an IF and Red Dot Design Award and, most recently, an M3 “Best of Show at @CES 2020.”
