What Makes the ALTIS Sigma Electric Dirt Bike Great

When it comes to high-performance off-road machines, few names generate as much buzz right now as ALTIS. The ALTIS Sigma has earned a reputation as one of the most capable electric dirt bikes on the market, and for good reason. It combines a genuinely powerful drivetrain, a race-ready chassis, and premium components into a package built for riders who want more than a casual trail toy. Available through Wyrd Ryds, the Sigma isn't just another entry in a crowded field of electric bikes, it's a purpose-built machine engineered to compete with gas-powered dirt bikes while offering the instant torque and low maintenance that only an electric powertrain can deliver.

A Motor and Battery Built for Serious Riders

The heart of the Sigma is its 25kW peak Hairpin motor, producing 27 to 34 horsepower and a massive 601 Nm (443 ft-lbs) of torque through a 39-tooth sprocket. That torque figure alone puts it in a different category than most electric dirt bikes on the market, delivering explosive acceleration whether you're launching out of a corner or climbing a steep grade. Top speed is rated at 80+ mph, making the Sigma one of the fastest electric off-road bikes available for adult riders who want genuine performance, not just a marketing claim.

Powering all that output is a 98V 35Ah (3402Wh) Samsung 50S lithium-ion battery pack, branded as the ALTIS PowerPack. It's an air-cooled system designed for consistent output under demanding conditions, and it charges fast  80% in about 2 hours and a full charge in roughly 3 hours using a standard 110V/112V outlet. For riders who log serious trail time, that kind of turnaround matters, and it's part of why the Sigma stands out among comparable Electric Bikes in this power class.

Chassis and Suspension Engineered for the Trail

Beyond the powertrain, the Sigma's chassis tells the rest of the story. It's built on a forged aluminum alloy frame with a 51-inch wheelbase, 35-inch seat height, and 13 inches of ground clearance  numbers that put it firmly in true dirt bike territory rather than a scooter-style crossover. Front suspension delivers 220mm of travel through an adjustable air spring setup, while the rear offers 85mm of travel through a linkage system, giving the Sigma the compliance needed to absorb rough terrain at speed.

Stopping power comes from heavy-duty 4-piston hydraulic brakes on 260mm front and 220mm rear discs, more than capable of matching the bike's acceleration. Spoked wheels with aluminum rims and CST tires round out a build that's clearly meant for real off-road use, not light recreational riding. A 3.5-inch TFT display keeps key data in view, and full lighting  headlight, tail light, brake light, and turn signals  makes the Sigma legal-ready for mixed-use riding where local laws allow.

Why the ALTIS Sigma Stands Out

What separates the ALTIS Sigma from other electric dirt bikes is how deliberately every component was chosen to support serious performance. The 450A controller matches the motor's output without bottlenecking power delivery, the 20mm rear axle and 520H chain are built to handle high torque loads without premature wear, and a max load rating of 300 lbs means the bike can handle bigger riders or added gear without sacrificing performance. Even at 198 lbs (90kg) with the battery installed, the Sigma manages to feel purposeful rather than bulky thanks to its aluminum frame construction.

For riders comparing options among E Moto Power Bikes or looking at Electric Moto Style Bikes as a category, the Sigma consistently comes out ahead on raw numbers: torque, top speed, suspension travel, and battery capacity are all near the top of their class. Wyrd Ryds offers the Sigma in Black and Red finishes, and because inventory is limited, interested buyers are encouraged to act quickly.

Who the Sigma Is Really For

The ALTIS Sigma isn't designed for casual, first-time riders. It's built for experienced off-roaders who want a machine that can go toe-to-toe with gas-powered competition while offering instant torque, quieter operation, and less maintenance overhead. The bike is sold strictly for off-road or track use, is speed and power limited to comply with applicable regulations, and requires buyers to be 18 or older with ID verification completed before shipping or in-store pickup. Given its price point and performance ceiling, it's best suited to riders who already understand suspension setup, throttle control, and the demands of aggressive trail riding.

Final Thoughts

Between its 601 Nm of torque, 80+ mph top speed, adjustable air suspension, and premium braking system, the ALTIS Sigma earns its reputation as a genuinely capable performance machine rather than just another electric dirt bike with big numbers on a spec sheet. At Wyrd Ryds, we see it as a serious investment, but for riders who want an off-road electric bike that can actually deliver on aggressive trail and track demands, the Sigma is difficult to beat.
