Altis Sigma

The Altis Sigma is where raw power meets refined engineering. Designed for riders who demand more from every trail, this next-generation electric dirt bike delivers explosive performance, precision handling, and cutting-edge technology in a lightweight, race-ready platform.

At the heart of the Sigma MX is a 97.2V 35Ah Samsung 50S battery, delivering 3.4 kWh of energy through an advanced 23kW (31HP) automotive-grade hairpin motor. The result? Instant torque, relentless acceleration, and a riding experience that feels as aggressive as it is controlled.

Built on a forged aluminum alloy frame, the Sigma MX balances strength and agility with just 88 kg of total weight. Its fully adjustable off-road air-spring suspension and long-travel setup are engineered to dominate rough terrain, while CST off-road tires and heavy-duty disc brakes keep you planted and in control when it matters most.

Tech-forward features like a 3.5” TFT display with NFC capability, five levels of regenerative braking, and fast charging (20–80% in just 2 hours) ensure the Sigma MX isn’t just powerful, it’s smart, efficient, and ready for modern riders.

With 601 Nm of torque on tap and a design built for serious off-road performance, the Altis Sigma MX isn’t just another electric bike, it’s a statement.

Ride harder. Ride smarter. Ride Sigma.
