ALTIS SIGMA

The Altis Sigma is a full-size electric dirt bike built for riders who want serious performance and stability. Designed for experienced teens and adults, it delivers strong acceleration, long-travel suspension, and a planted chassis that stays composed at speed and on rough terrain. With larger wheels and a powerful electric drivetrain, the Sigma feels closer to a true full-size dirt bike than a compact electric platform. This is not an entry-level machine — it’s built for riders ready to push harder and ride farther.
