Altis Sigma | Best Selling E-Moto by Altis Powersports

Description

Overview

The 2025 Altis Sigma Standard Edition, delivers one of the strongest high-voltage e-moto riding experiences in its class. Built around a 98V power system, a high-efficiency hairpin motor, and a premium 35Ah Samsung 50S battery, this version of the Altis Sigma set the stage before the Limited Edition release. It offers explosive torque, smooth throttle control, adjustable suspension, selectable ride modes, and a lightweight chassis that sits comfortably between a Sur-Ron class bike and a full-size MX machine.

With five levels of regen braking, a bright 3.5 inch TFT display with NFC, and two factory wheel configurations, the non-LE Sigma gives riders a well-rounded platform ready for real trail and MX riding with minimal setup required. For riders stepping into higher voltage without Varg-level prices, the 2025 Sigma remains one of the best values in the category.
