Cake Kalk - Make Dirtbikes Clean Again
The Cake Kalk electric dirt bike is the machine that introduced Scandinavian minimalism to a category that had spent decades being defined by noise, exhaust fumes and visual complexity. Founded by Stefan Ytterborn, formerly of POC protective gear, Cake set out not just to electrify the dirt bike but to redesign it from first principles. The result is a motorcycle that looks like it belongs in a design museum and performs like a competition enduro bike.
Materials and Construction
Every component on the Kalk is either aircraft-grade 6061 aluminium or carbon fibre. The frame and swingarm are machined from aluminium, keeping weight down to around 155 pounds while providing the rigidity a hard-ridden dirt bike demands. Body panels are carbon fibre, chosen for the combination of low mass and high strength that defines the material. Nothing is generic: stems, hubs, brackets and chassis details are all custom-made for the Kalk rather than sourced from a shared parts bin. The visual result of this level of specificity is a bike that reads as a single coherent object rather than an assembly of off-the-shelf components.
Performance Specifications
The powertrain is a mid-mounted electric motor delivering 15kW, fed by a 2.6kWh lithium-ion battery pack. Top speed is 50mph and range sits at approximately 50 miles, appropriate for an off-road machine where sustained high-speed running is the exception rather than the rule. Suspension is full Ohlins: an inverted fork and monoshock with close to eight inches of wheel travel. At 155 pounds, the Kalk's power-to-weight ratio gives it the agility of a competition motocrosser, while the absence of engine vibration and gearbox management simplifies the riding experience down to pure throttle and chassis control.
Why It Matters
The Kalk is not a compromised road bike fitted with knobby tyres. Cake designed it specifically for off-road use, which is precisely why they could strip away every concession to street legality and build purely for function and form. The initial production run was limited to 50 units, a deliberate constraint that kept quality control absolute and made each bike a collector's piece. Since then Cake has expanded the range with variants including the street-legal Kalk and the utility-focused Osa, but the original Kalk remains the purest expression of what the company set out to prove: that an electric dirt bike can be better, not just cleaner.
The Cake Kalk is available through TheArsenale alongside the Cake Osa+ electric utility bike. For the broader range of performance electric two-wheelers, the e-bikes collection includes everything from off-road specialists to urban commuters.
