144V Electric Motocross Platform Built for Racing, Desert, Enduro, and Full-Size E-Moto Performance
The all-new Altis Omega, formerly known as the Sigma Mega, is Altis’ most advanced electric dirt bike platform to date. Designed and engineered in California, the Omega was built from the ground up as a true full-size electric motocross machine for riders who want serious race-level performance without compromise.
The Omega is one of the most advanced all-electric dirt bikes ever developed for the modern 250cc class. It combines championship-level performance with fully adjustable ergonomics that evolve with the rider’s skill, confidence, and riding style. From first rides to full race pace, the Omega was designed to grow with the rider instead of limiting progression.
Built around a high-voltage 144V-360V powertrain system, the Omega delivers explosive acceleration, incredible throttle response, and massive wheel torque while maintaining the lighter, more agile feel riders expect from a modern motocross platform. Altis developed the Omega to bridge the gap between lightweight e-motos and full factory-level race bikes, creating a platform that feels at home on motocross tracks, open desert terrain, hard enduro trails, and competitive race environments.
Delivering instant electric torque, zero emissions, and virtually no routine engine maintenance, the Altis Omega offers a cleaner, quieter, and smarter alternative to traditional gas-powered 250's while producing power comparable to many modern 450cc motocross machines. Even with that level of performance, the Omega sacrifices nothing in speed, control, suspension capability, or overall ride experience.
With full-size 21/18 wheel sizing, motocross-standard cockpit dimensions, race-focused suspension options, and compatibility with KTM and Stark wheel platforms, the Omega was designed to give riders real setup flexibility without locking them into proprietary sizing.
Not a toy. Not a compromise. Just pure, unfiltered electric motocross performance ready to race straight out of the crate.
The Omega Pro Version builds on the standard platform with upgraded race-oriented suspension and drivetrain components for riders pushing harder on motocross tracks, race courses, and rough terrain.
KYB Front Fork: 250mm travel KYB suspension

Torque: 885 lb-ft, 1200 N.m
Power System: 360V architecture
Battery: 6480Wh Altis Power-Pack Battery
Launch Time: December of 2026

Chassis, Suspension, and Race-Focused Design
The Omega was designed to ride like a real motocross bike, not a compact e-moto stretched beyond its intended purpose. Altis focused heavily on rider ergonomics, suspension capability, and compatibility with proven motocross standards to make the bike easier to race, tune, and customize.
Wheel Compatibility: KTM and Stark VARG compatible wheel fitment
KTM Wheel Compatibility: KTM 125cc-500cc models from 2004-2024 including KTM 450 SX-F
One of the biggest advantages of the Omega platform is the use of common motocross sizing and fitment standards. Riders can more easily swap wheels, bars, controls, tires, and setup components without being limited by highly proprietary dimensions.
Display and control Integration
The Altis Omega uses the same tuning interface and display system found on the 2026 Altis Sigma platform. Riders can quickly access onboard adjustments and ride settings directly through the bike display.
Power mapping adjustment
Throttle sensitivity tuning
Regen braking adjustment
Custom ride mode configuration
(Altis is also developing a dedicated smartphone app With Eta that will be after the bike release that will allow riders to fine-tune bike behavior directly from their phone.)
Why the Altis Omega Stands Out
The Omega represents one of the biggest performance jumps the e-moto market has seen so far. The combination of a 144V-360V high-voltage system, automotive-standard hairpin motor design, full-size motocross geometry, and compatibility with real moto components gives riders a platform that feels significantly more serious than traditional lightweight electric dirt bikes.
The high-voltage architecture helps improve efficiency and reduce heat buildup during aggressive riding, especially during longer motos, race conditions, and high-speed desert riding. Combined with the lightweight chassis and full-size suspension package, the Omega delivers the kind of acceleration and control serious riders have been asking for from the next generation of electric motocross bikes.
For riders looking to move beyond smaller e-motos without stepping into the extreme weight and cost of some larger electric race bikes, the Omega lands in a very unique and exciting category.
