The Altis Sigma: The High-Voltage E-Moto That Redefines the Category

Welcome to the new king of electric dirt bikes. The Altis Sigma isn’t just an upgrade—it’s a revolution. In 2026, the “60V era” officially came to an end. The Altis Sigma arrived with a groundbreaking 98V system, shattering the performance ceiling of lightweight e-motos and setting a new standard for what riders can expect from a production electric dirt bike. If you’re looking to buy a high-performance electric dirt bike that delivers 250cc-rivaling power, premium components, and serious value, your search ends here. This is the bike that has the entire e-moto community talking, and for good reason.

The Motor: Hairpin Power That Dominates

At the heart of the Sigma lies a state-of-the-art hairpin motor—an automotive-grade technology that delivers superior power density and efficiency compared to traditional brushless motors . The 2025 model pumps out an impressive 22kW (approx. 27-30 HP) peak power . But the 2026 version takes it even further, featuring an upgraded 25kW (34 HP) peak hairpin motor for even more explosive acceleration .

• Torque: Both versions deliver jaw-dropping torque. With the MX 44T sprocket, the Sigma achieves up to 601 Nm (443 ft-lbs) of torque at the rear wheel . The Limited Edition even pushes this to an incredible 626 Nm . This is the kind of instant, neck-snapping acceleration that leaves gas bikes in the dust.
• Top Speed: The 2025 model achieves a proven 70+ MPH top speed unlocked . The 2026 version, with its upgraded motor and 39T sprocket, pushes the limit to an exhilarating 80+ MPH (128+ km/h) .
• What This Means For You: This isn’t just a trail bike; it’s a full-blown performance machine capable of dominating open terrain, motocross tracks, and technical singletrack with equal authority.

The Heart: Cutting-Edge 98V Samsung Battery Technology

The Altis Sigma is built on a true 97.2V nominal (98V class) high-voltage powertrain . This isn’t just a number; it’s a paradigm shift. A 98V system is significantly more efficient than traditional 60V or 72V setups. It runs cooler, delivers more consistent power, and provides better range, especially when you’re pushing the bike hard .

Powering this system is a premium Lithium-Ion ALTIS PowerPack featuring high-quality Samsung 50S cells . The 2025 model packs a 35Ah (approx. 3.4 kWh) battery , while the 2026 version features an upgraded 97.2V 35Ah (3402Wh) Performance Pack with an enhanced BMS for improved efficiency and longevity .

• Range: Riders can expect around 50 miles of range under optimal conditions . This is more than enough for a full day of aggressive trail riding or track sessions.
• Charging: Minimize downtime with rapid charging. The Sigma can go from 20% to 80% in just 2 hours (120 minutes) , and a full charge from 20% to 100% takes about 3 hours (180 minutes) .

Built to Thrash: Premium Chassis and Race-Ready Suspension

The Sigma’s power is perfectly matched by its robust and capable chassis.

• Frame: The core is a forged aluminium alloy frame , offering a perfect balance of lightweight agility and immense structural rigidity for aggressive riding.
• Suspension (2025): The 2025 model features an adjustable air-spring fork with 200mm of front travel and a linkage shock with 85mm of rear travel .
• Suspension (2026): The 2026 version gets a significant upgrade with 220mm of front suspension travel and revised rear suspension with a linkage system . This provides even better absorption of big hits and improves control on rough terrain.
• Brakes: Stopping power is handled by a heavy-duty hydraulic disc brake system with a massive 260mm front rotor and a 220mm rear rotor . This setup provides fade-free, confident stopping power in all conditions. The 2026 version further reinforces this with a 20mm rear axle for increased strength and durability .
• Wheels and Tires: The bike comes with spoked aluminum rims wrapped in aggressive CST off-road tires . You can choose between the 19″/16″ MX configuration for track-focused agility or the 19″/19″ Trail setup for stability and rollover capability at high speed .
