About CAKE

CAKE is a Swedish company, with a clear mission, to contribute to speeding up the transition towards a zero-emission society, while enhancing excitement and fun, by developing a light, silent and clean hi performance electric off-road motorbikes.

The category of light electric off-road motorbikes has been evolving from small dedicated builders, assembling and customizing standard parts from the cycling and motorcycling space.

These hybrids, equipped with motors, batteries, and controllers, off the shelf and soaped, pointed out the direction towards something that will change the future of riding.

The properties of an electric drivetrain, different to a combustion engine, means a number of things.

The weight aspect is one. Being able to reduce the weight dramatically, compared to what a similar combustion bike would be, supports snappy and lively rides, as well as inviting anybody despite physical condition to comfortably handle the bike.

The fact that it’s nearly silent, boosts the experience, serving in absolute presence, out exploring.

It is also enhancing the level of respect towards the surroundings, sharing the space, whether it’d be fellow hikers, wild animals or maybe even your neighbors, riding your backyard track.

Another side, meaning that there are no fluids, grease, gasoline or oil, like magnets sucking dirt, it’s more like a bicycle.

The simplicity of riding is evident

Thanks to the progressive span of an electric motor, no gears are needed. -The hassle of clutching and changing gears doesn´t exist. Throttling and braking are all there is to it. That together with the lightness, the absence of noise and the fact that one can preset the level of bike performance, invites everyone, no matter what previous experience, to enjoy and to explore.

Spending hours in the garage is history as maintenance is very limited.

Compared to a combustion engine, there are very few moving parts and to take the level of simplicity further the drive train has a direct drive. The level of maintenance is marginal. Clean the bike, you might need to change a tire if you get a flat, make sure to service the brakes like on an MTB, check your suspension from time to time and just charge it, for more riding.

KALK CAKEs first bike

The KALK model is a first among a number of models to come.

The focus here has been off-road performance and innovation.

The ride is strongly influenced by DH and Enduro MTBs, in terms of geometry, suspension, stance, components, and handling.

As there weren’t anything off-the-shelf to support the category, every single component had to be developed from an empty sheet to support the intended level of quality and durability:

The sizing, the geometry, and engineering of axles, hubs, rims, the cockpit, and suspension, as well as building and customizing the different parts of the drivetrain, together with developing a whole new chassis; having led to numerous patent pending’s, constituting the new category.

Reason behind the name:

KALK

The name KALK for CAKEs first model and platform has its reason because of KALKsten or Limestone, being the bedrock of the island of Gotland.

The Gotland bedrock was largely made up of coral reefs, created in the tropical sea four hundred million years ago. The continental drift took Gotland on a ride from the tropical waters, made a few turns and placed it in the Baltic Sea, where the rest of the surroundings are mostly granite.

That white limestone gives Gotland a special light and flight, which is unique.

And that same white limestone is what we use and will be using for CAKE tracks.

It´s perfect for building jumps, curves, banks, and rollers. Add a little water and it becomes beautifully solid.

KALK it is.

Specifications

The CAKE KALK bike, built for light off-road performance, uses an industrial standard IPM motor, customized for CAKE and made in Europe.

It´s a 15 kW mid motor, powered by a 51.8 Volt, 50Ah battery for torque and range.

With the intention of simplicity, promoting easiness in terms of riding as well as maintenance, it´s a light bike weighing in at sub 70 kilos, using a single pivot direct drive, reducing the number of heavy and moving parts.

The suspension is specifically developed, by Öhlins supporting the category of hi-performance at minimum weight.

Nothing has been left aside and every part including axles, hubs, cockpit, sprockets and even the tires (to minimize wear and footprint of trails being used), have been explicitly designed and engineered for the ultimate experience.

The light and snappy ride, with its focus on off and on trail riding, in the outback, means that its main character is about torque and acceleration while providing a quiet gliding and surfy experience.

Thanks to its digital presetting it´ll let anyone fly at their own level.
