Product detailed description
ALTIS SIGMA MX – lightweight and powerful electric MX/enduro motorcycle
ALTIS SIGMA MX is a lightweight, agile and exceptionally powerful electric MX/enduro machine designed for off-road riding. Thanks to its peak wheel torque of 601 Nm, high-voltage battery 98 V / 35 Ah (≈3.4 kWh) and weight of around 84 kg, it tackles tracks and technical terrain with complete confidence. Equipment includes a colour TFT display, riding mode tuning via mobile app and modern NFC technology.
The first 98 V electric bike of its kind
Altis Sigma brings a new standard to the world of compact electric enduro bikes – as one of the first it offers a 98 V architecture that delivers brutal pull, instant throttle response and stable power even under extreme load. High voltage means higher efficiency, less heat build-up and aggressive acceleration that typical 72 V bikes simply cannot match. It is built for riders who want to push the limits – both their own and the bike’s.
22.5 kW of raw power
Altis Sigma MX ranks among the very top of the electric enduro world. With a peak output of 22.5 kW, it will fire you up a hill before you have time to roll off the throttle, and its brutal acceleration easily handles steep climbs, fast straights and controlled wheelies on demand.
The massive 98 V Samsung battery with a professional NEMA L16-30P connector ensures safe power delivery even under maximum load. Whether you are conquering rocky ascents or flying along dusty tracks, the Sigma takes it all in stride with impressive ease and stability.
3.5" TFT display – all key information in one place
The clear and bright 3.5" TFT display shows your speed, battery status and live voltage in real time. You always have full insight into what the bike is doing – whether you are carving through forest singletrack or navigating demanding technical sections.
Total control – 5 levels of regeneration
Altis Sigma offers five levels of regenerative braking, allowing you to fine-tune the bike’s behaviour precisely to your preferences. From gentle slowing to aggressive engine-braking feel – you always retain maximum control, even in the toughest conditions.

Performance and riding character
The direct drive without intermediate reduction and the lightweight chassis combined with 22.5 kW peak power give the SIGMA an instant throttle response. The bike feels stable yet extremely agile – ideal for MX tracks, enduro trails and fast off-road transfers. In real-world off-road mode the top speed is around 110–112 km/h, and thanks to the high torque the acceleration is genuinely fierce.
Battery and range
The integrated lithium-ion battery 97.2 V / 35 Ah (≈3.40 kWh) is among the largest in its class. In eco mode the range reaches up to around 120 km (depending on riding style, terrain and temperature). Adjustable regenerative braking extends the range and reduces brake wear on long downhill sections.
Chassis and components
Suspension is handled by an upside-down HTW front fork with approx. 200 mm of travel and a rear multi-link HTW shock with approx. 210 mm of travel. Braking performance comes from hydraulic brakes with four-piston calipers and 260 mm front and 220 mm rear discs. Wheel sizes of 19″ front and 18″ rear give an ideal balance between high-speed stability and agility in technical terrain.
Smart modes and configuration
Using the clear TFT display and companion mobile app, you can fine-tune the bike’s behaviour in detail – adjust power maps, throttle response and the intensity of regenerative braking. SIGMA can thus be tailored both to beginners and to experienced riders who demand maximum control over how the machine behaves.
Homologation and use
This model is not homologated for use on public roads – it is a pure off-road version intended exclusively for riding away from public traffic. Enjoy it only on designated off-road areas and always follow local laws and regulations. For selected model variants, versions with L1e or L3e homologation are available.
