Altis Sigma Review: Is This 98V Electric Dirt Bike the Best Off-Road Machine?

High Torque, Fast Charging, and Off-Road Dominance

There comes a moment on the trail when you realize you’re not riding a mere machine—you’re taming a beast. The Altis Sigma is that rare creature: an electric off-road marvel designed for those who crave unbridled power and uncompromising performance. If you’re built for the rugged unknown, this is the ride that will push you to new limits.


Unleashing Raw Power and Performance

At its heart, the Altis Sigma packs a serious punch. With a 22.5-kilowatt peak hairpin motor that delivers a robust 72 newton-meters of torque, every twist of the throttle unleashes a torrent of energy. For riders who demand even more muscle, options include setups that boost torque to 533 newton-meters with a 39-tooth sprocket—or a headier 601 newton-meters with a 44-tooth variant. Whether you’re tearing up steep inclines or launching off rugged trails, the acceleration is relentless, pushing you to speeds that flirt with 113 kilometers per hour.


High-Voltage Innovation: The Battery and Charging Advantage

Powering this trail warrior is a meticulously engineered battery pack featuring 97.2 volts and a 35-ampere-hour capacity built from Samsung 50S cells. With an energy reservoir of 3,402 watt-hours, the Altis Sigma is the first of its kind to embrace a 98-volt setup. This high-voltage system doesn’t just mean numbers—it translates into real-world performance. Enjoy rapid charging from 20% to 80% in just 2 hours and a full charge in 3 hours, ensuring that your adventures are never put on hold for long.


Superior Suspension, Braking, and Tire Technology

Navigating treacherous terrain demands a bike that’s as responsive as it is resilient. The Altis Sigma rises to the challenge with an adjustable off-road air-spring suspension system that offers 200 millimeters of front travel and 85 millimeters of rear travel (with linkage). This, combined with heavy-duty disc brakes featuring five regenerative braking modes, means you have both the agility to absorb shocks and the control to decelerate on a dime. Top-tier off-road tires and spoked wheels with aluminum rims complete the package, ensuring that every twist, turn, and jump is met with confidence and precision.


Engineered for Endurance: Chassis and Design

Built from forged aluminum alloy, the Altis Sigma’s chassis is as tough as it is lightweight—hovering around 85 kilograms (battery included). Its geometry, defined by a 1,285-millimeter wheelbase, a seat height of 840 millimeters, and a 26° steering head angle, has been honed for optimal stability and nimbleness on the roughest landscapes. With a generous 300-millimeter ground clearance, this machine is ready to conquer obstacles without slowing you down. Every detail of its design speaks to a commitment to durability and performance, ensuring the ride remains smooth even when the going gets truly rough.


Cutting-Edge Technology at Your Fingertips

In the digital age, riding isn’t just about raw mechanics—it’s also about having the right information at a glance. The Altis Sigma comes equipped with a 3.5-inch TFT display featuring NFC connectivity. This intuitive interface delivers real-time data on speed, battery status, and braking levels, allowing you to stay focused on the ride. It’s a blend of rugged reliability with modern technology, ensuring that whether you’re navigating twisty trails or powering through a steep descent, you’re always in command.


The Verdict: A Ride for the Relentless Adventurer

For those who live for the thrill of uncharted trails and the rush of untamed power, the Altis Sigma isn’t just another electric dirt bike—it’s a revolution on two wheels. Priced at $5,499, it offers a superior price-to-performance ratio that challenges competitors and delivers an experience that’s both exhilarating and efficient. With delivery dates slated for early February 2025 for orders placed after November, now is the time to consider joining the ranks of riders who refuse to settle for ordinary.

In my many years on the road, I’ve rarely come across a machine that captures the spirit of adventure quite like the Altis Sigma. It’s raw, it’s relentless, and it’s designed for those who don’t just ride—they conquer. If you’re ready to leave a trail of dust in your wake and redefine what it means to be free on the open terrain, then this beast is calling your name.


Embrace the ride, and let the Altis Sigma take you where few dare to go.

Cons

  1. Not for Beginners – With an immense power output and aggressive torque, this is not a bike for casual riders or those new to off-roading. It requires experience and skill to handle properly.
  2. Limited Range – Despite its high-capacity battery, the 80-kilometer range may not be enough for long-distance adventures without recharging. Riders planning extended off-road trips may need to strategize charging stops.
  3. Longer Full Charging Time – While the 2-hour charge time to 80% is impressive, reaching 100% still takes three hours, which might not be ideal for those who need a quick top-up for longer rides.
  4. Seat Height May Not Suit All Riders – With a seat height of 840mm, shorter riders may find it difficult to plant their feet firmly, which could affect confidence and control, especially in technical sections.
  5. No Street-Legal Features – Unlike some competitors, the Altis Sigma is not designed for street riding—no turn signals, license plate mount, or other street-legal essentials. It’s strictly an off-road beast.
  6. Limited Aftermarket Support – Since the bike is relatively new to the market, aftermarket parts and customization options may be limited, at least initially. Riders looking for extensive modifications might need to wait for third-party upgrades.
  7. Heavier Than Some Rivals – Weighing 85 kilograms, the Altis Sigma is heavier than some electric dirt bikes in its class, which may affect handling for riders looking for a feather-light experience.
  8. High Performance Comes at a Cost – While $5,499 is competitive for its features, some riders may find it expensive compared to lower-cost alternatives like the Surron Light Bee or Talaria Sting, which cater to a broader audience.

Verdict

The Altis Sigma is an off-road powerhouse built for riders who demand maximum torque, high voltage efficiency, and premium suspension in a dirt bike. With cutting-edge technology, a top-tier braking system, and a lightweight yet rugged frame, it’s a machine that stands out among electric dirt bikes. The high-voltage 98V system and 22.5kW motor put it in a class of its own, delivering an adrenaline-fueled experience for serious off-roaders.

However, it’s not for beginners. The aggressive power delivery and steep torque curve require a skilled rider, and the range may be limiting for those planning extended rides. Additionally, it’s strictly an off-road bike—street riders will need to look elsewhere.

For those who live for speed, raw power, and pushing the limits on the toughest trails, the Altis Sigma is an absolute game-changer. It delivers premium performance at a competitive price, making it an excellent choice for thrill-seekers who want a trail-ready electric dirt bike straight out of the box.

$5,499

If the Altis Sigma feels like a full-throttle off-road dominator, the Luna Cycle Talaria XXX Black Edition is its leaner, more agile counterpart—offering a compelling alternative at a lower price point. Weighing just 125 pounds, this e-bike is built for riders who crave effortless maneuverability without sacrificing power. Packing a 6,500-watt IPM motor with 95% efficiency, the Talaria XXX delivers an electrifying ride, while its 40Ah battery (21700 LG cells) provides 2,400 watt-hours of energy for sustained performance. Unlike the brute-force torque of the Altis Sigma, the XXX excels in precision handling, making it ideal for tight trails, technical riding, and urban adventures. With four levels of regenerative braking, hydraulic 4-piston brakes, and Super Moto wheels, it’s a high-performance machine that balances power, weight, and affordability. Priced at $3,000, it undercuts the Sigma significantly, making it an excellent choice for riders looking for a lighter, more nimble e-bike with serious power—without stretching their budget to the extreme.
