The Altis Powersports Sigma is an electric dirt bike designed for off-road trail and motocross riding, offered in two wheel configurations — a Trail variant (19"/19") suited for higher-speed open terrain, and an MX variant (19"/16") oriented toward motocross-style riding. Built around a high-voltage lithium-ion battery pack with Samsung cells and an automotive-grade hairpin motor, the Sigma targets riders seeking a capable, battery-powered alternative to traditional gas-powered off-road bikes. Altis Powersports positions the Sigma as a performance-focused option in the growing electric off-road segment, with features such as adjustable air-spring suspension, regenerative braking, and a TFT display with NFC.
