Altis Sigma (Standard Edition) | Best Selling E-Moto by Altis Powersports
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.

Why Riders Choose the Non-LE Sigma
The 2025 non-Limited Edition Sigma gives riders the full 98V experience at a more accessible price. The torque delivery, the rigid chassis, and the long wheelbase translate to strong straight-line stability and a planted feel in high-speed sections. The Samsung pack provides excellent voltage support under load, and the regen tuning makes steep descents more controlled while improving range.
Altis designed this platform to be simple to maintain and easy to upgrade. Out of the box, the suspension, geometry, and power system give riders enough performance to handle single-track, MX practice, and everyday trail riding without immediate modifications.

- Riders stepping up from 60V and 72V platforms
- Off-road and single-track riders who want high torque and smooth power
- MX riders who want a lightweight EMoto with real voltage overhead
- Anyone who wants a ready-to-ride 98V system without paying Limited Edition pricing
- Riders comparing Sur-Ron, Talaria, and similar mid-weight e-motos
Fitment
- Applies to the 2025 Altis Sigma Standard Edition
- Covers both 19/19 and 19/16 factory wheel configurations
- Compatible with all OEM Altis Sigma 98V components, chargers, and accessories

Off-road Top Speed:
NOTICE: Some vehicles include a “City Mode” that limits top speed to 20 mph, making them compliant with many city and state regulations for use on public roads, bike paths, sidewalks, and parks. Other vehicles may feature an “Off-Road” or “Race” mode, which increases performance and top speed (more than 20mph) but may render the vehicle illegal for use in the city or on public roadways. Vehicles without a “City Mode” and exceed a top speed of 20mph are not for use on public roads, bike paths, sidewalks or in parks, and are intended for off-road, privately owned land or track use only.
