battery & riding modes

easy charging, 3 ride modes, no gears

Thanks to the high rpm and progressive span of the electric motor, throttling, and braking are all there is to it. Fast standard outlet charging. Best-in-class power density and state-of-the-art motor control algorithms.

ride modes
  1. explore: The ultimate mode during exploration. It has a limited top speed to 45 km/h (28mph) with a 3-4 hrs battery range.
  2. excite: Enduro or active trail riding. 1-2 h riding time. With a top speed of 70km/h and good acceleration, this mode is perfect for enduro riding out in the woods.
  3. excel: Maximal torque and speed, with no restrictions when it comes to performance. This mode is perfect when you need all power available. Riding time up to 1 h.

drivetrain & brakes

a unique power to weight formula

Powerful drivetrain with 280Nm on the rear wheel combined with being super light creates a unique power to weight formula. Superior nimbleness and speed in technical, compact formats.

suspension, wheels & tires

robust suspension & MX tires and rims for maximum performance

Equipped with 200mm travel the upside-down MX spring forks with rebound adjustment offers everything you need. The MX tires and aluminum MX rims are designed to meet the demand of riding on track or enduro trails with maximum performance.

riding reviews

”Like flying down an endless DH course with no need for a hill."
Robin Wallner
Ibis cycles Enduro race team
”the reason the Kalk works so well is the use of a frame, a motor, suspension, wheels, tires, and cockpit all designed specifically for this weight class and riding style. Nothing is over or under-built, and that means lightweight, high performance"
-BikeRumor
”The Kalk OR is a super light bike with face-melting amounts of all-electric torque and the most premium parts."
- Digital trends
”Super light, super torque, insane. Must be worlds fastest bike on narrow trails."
Robert Kvarnström
2x Swedish enduro champion, world championship contender

both proffessionals and beginners love this bike

Classified as Off-road, no special licence is required. This bike got wheels adapted for the race course but the sense of control makes it easy to ride even for beginners. Few moving parts, no filters, no oils – life gets easier with your CAKE.

about Kalk INK race

Kalk OR race and Kalk INK race are a power to weight ratio optimization pursuit, building a chassis, as light and lively as possible, around the electric drivetrain, in contrast to the normal procedure, merely swapping from combustion to electric, in a gasoline chassis (extremely heavy).

The inspiration comes from the first enduro competition a Kalk attended. A brilliant result combined with the demand for knobby tires. It’s important to understand that despite the good results vs traditional dirtbikes, the Kalk, with or without the race kit, is not engineered to imitate or to compete against combustion engine dirt bikes.

More about the Kalk INK race

The Kalk is the first step in establishing a new category of motorbikes, designed for a new user matrix. It’s about building light, quiet and clean, easy to ride, low maintenance, super nimble, never buying gas or filters, high performance, ride without disturbing or polluting. 

Explore new areas with respect.

Design and engineering of the Kalk:
The Kalk is engineered around the electric drivetrain to maximize the riding performance. The electric drive train is completely different from an internal combustion engine, with many unique benefits.

An electric drivetrain features instant torque from zero, direct drive, no need for a clutch, few moving parts, low tinkering, no fumes, no sounds, no filters, no oils, tuneable riding modes and regen braking, responsiveness, great throttle control, and swappable batteries.

All parts and components are developed from scratch to keep the weight down at with highest possible performance. Everything from the rims, hubs, stems to the custom Öhlins suspension is engineered and dimensioned, specific for the Kalk and the new category; lightweight electric motorbikes. The components are in a new category and derive from the most sophisticated DH components in terms of technology, materials, and manufacturing, but heavily reinforced, rather than downscaled MX components.
Standard DH parts are engineered for DH bicycles and are too weak. On the other end, MX components simply are too heavy.

Building light electric motorbikes for the ultimate, uncompromising off-road experience requires components engineered for it.
Simply combining off-the-shelf parts of the MTB and motorbike world would result in more parts, bolts, tinkering, welds, impaired geometry, and a compromised riding experience. As mentioned, the MTB components are too weak for a 69+kg (Kalk OR) motorbike, and the MX parts, too heavy, not serving for the specifics of the electric drivetrain.
Same thing goes for traditionally designed electric dirtbikes that are engineered and optimized for a combustion engine, where the ICE is simply swapped for an electric drivetrain and therefore not particularly efficient.
