The electric dirt bike world moves fast, but every once in a while, a new manufacturer drops a machine that completely alters the hierarchy of performance. While most brands have been safely playing in the 72V space, Altis Powersports stepped up and shattered expectations by delivering high-voltage platforms built to dominate straight out of the box. With the release of the heavy-hitting Altis Sigma and the compact Altis Delta, the eMoto community is asking: Does Altis offer enough value and engineering to dethrone the reigning champions?
Let’s tear down the mechanical specifications, high-voltage battery architecture, and real-world ride handling of the Altis lineup to see if these machines deserve a spot in your garage.
The High-Voltage Breakdown: Altis Sigma vs. Altis Delta
Altis does not build slow bikes. They have structured their lineup to offer massive power-to-weight ratios across two distinct frame sizes, making them immediate threats to heavily modified aftermarket competitors.
The Altis Sigma (The 98V Beast): Features a massive 98V high-voltage system paired with a 25kW (33.5 HP) peak output motor. It relies on a Tesla-style hairpin-wrapped motor for top-end efficiency and can reach blistering speeds of 80 MPH.
The Altis Delta (The High-Output Pit Bike): Built on a slightly smaller frame layout with a 72V 35Ah Samsung cell battery. Pushing 13kW of peak power, it achieves a top speed of over 60 MPH while retaining a nimble 17/14 wheel configuration.
Instead of forcing you to spend thousands of dollars on aftermarket controllers and battery swaps, Altis gives you hyper-bike performance directly from the factory floor.
Real-World Performance: What Makes Altis Different?
1. The 98V Power Band and Linear Throttle Control
On a traditional 72V bike, full-throttle bursts can cause early battery sag and heat buildup. The Altis Sigma’s 98V architecture requires far less amperage to generate its 25kW peak power. The result? Relentless pulling power that stays completely linear from 0 to 80 MPH. Thanks to its advanced field-oriented controller (FOC), the initial throttle response is buttery smooth, meaning you can comfortably track low-speed technical single-tracks without experiencing jerky power surges.
2. Premium Motocross-Grade Chassis Integration
Altis didn’t just drop a massive motor into a bicycle frame. The Altis Sigma behaves like a legitimate motorcycle on the trail, weighing in at roughly 198 lbs to provide a heavily planted, confident feel at high speeds. The suspension setup is incredibly robust, featuring a 220mm dual-spring front fork and upgraded linkage dust seals to survive brutal off-road conditions. Stopping power is handled by massive 260mm front and 220mm rear hydraulic rotors, giving you absolute control when braking into sharp corners.
3. Rapid Supercharging Capabilities
One of the biggest pain points for eMoto riders is waiting around for batteries to replenish. Altis directly addresses this by including a high-output supercharger with the Sigma platform. Utilizing its dense cell architecture and upgraded internal Battery Management System (BMS), the bike can charge from 20% to 80% in just two hours. You can plug in during a lunch break and be completely ready for a heavy afternoon trail session without missing a beat.
The Verdict: Which Altis Model Is Right for You?
Choose the Altis Sigma if:
•You are an experienced off-road rider looking for true 250cc gas dirt bike acceleration and an 80 MPH top speed.
•You want factory-installed 98V high-voltage power without the risk or cost of custom garage builds.
•You ride in open deserts, steep hill climbs, or fast tracks where thermal management is vital.
Choose the Altis Delta if:
•You prefer a lighter, more nimble “pit bike” footprint that is exceptionally easy to throw around on tighter single-tracks.
•You want high-end component quality—like full motorbike hydraulic brakes and aggressive moto tires—on a highly agile frame.
