2026 Altis Sigma Electric Dirt Bike | 25kW 98V E-Moto
Experience the pinnacle of electric motocross with the all-new 2026 Altis Sigma Electric Dirt Bike. Engineered to dominate both trails and open terrain, the 2026 edition undergoes a massive evolution, delivering more raw power, refined control, and upgraded durability. Powered by a groundbreaking 98V system and a newly upgraded 25kW peak Hairpin motor, this hyper e-moto leaves traditional gas bikes and standard electric pits in the dust.
Whether you choose the high-speed stability of the standard Sigma (19"/19") or the aggressive, torque-focused agility of the Sigma MX (19"/16"), the 2026 Altis Sigma is built to redefine your off-road adventures.
The 2026 Altis Sigma features significant factory upgrades from previous generations, focusing on higher top speeds, structural reinforcement, and superior suspension:
-
Next-Level Power Output: Upgraded from 22kW to a blistering 25kW (34 HP) peak power with a higher-RPM hairpin motor.
-
Blistering Top Speed: Reach up to 81+ MPH (on the 19/19 setup) with explosive acceleration delivering 601 Nm of torque.
-
Upgraded Front Suspension: Moving to a heavy-duty 220mm Dual Spring Fork for vastly improved front-end stability over rough terrain.
-
Heavy-Duty 520H Chain: Upgraded from the older 428H chain to handle the massive increase in instant torque.
-
Refined Cockpit & Ergonomics: Upgraded to 1 1/8” (28.6mm) handlebars and a higher 35”/36” seat height paired with 13” of ground clearance for a true moto-style stance.
-
Enhanced Visuals: Features a brand-new, ultra-bright Baja-style LED headlight for night riding.

⚡ Automotive-Grade 98V Powertrain
At the heart of the Sigma is the industry-first 98V architecture paired with a high-capacity 97.2V 35Ah (3402Wh) Samsung 21700/50S performance battery pack. Managed by an advanced BMS and a refined 450A/500A Phase-Amp controller, power delivery is smooth down low yet hyper-aggressive at the top end.
🏁 Choose Your Style: Standard vs. MX
