Kalk INK race
10 500 USD
A light & pure off-road electric motorbike. The Kalk INK Race is based on the same technology as the Kalk OR Race and built for riding on tracks or enduro trails. Slightly heavier with a simplified and yet sturdier suspension.

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.
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.
all the specs
battery & ride mode
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.
* The actual range depends on a number of different aspects, e.g. riding style, rider weight, weather conditions, temperature, road surface and tire pressure.

brake modes
1) Freewheel: No motor brakes. Gives the same sensation as riding a bike, perfect for mellow riding and the ultimate freedom experience.
2) 2-stroke motor brake with energy regeneration. Moderate engine brake. As you release the throttle you feel the bike slowing down at a slow pace.
3) 4-stroke motor brake with energy regeneration. When releasing the throttle, the bike will slow down significantly. This brake mode is best suited for technical tracks where full control for the bike is needed.
