The Specialized Turbo Levo 4 Expert is a full-power electric mountain bike built to elevate your trail riding beyond ordinary limits. From its meticulously engineered frame to its next-generation electronics, this bike is designed for riders who demand power, precision, and adaptability in every ride. At the heart of this revolutionary platform is the all-new Specialized 3.1 motor, delivering a formidable 101Nm of torque and 666 watts of peak power. The result is a ride experience that feels like an extension of your own strength—fluid, responsive, and fast. With the Levo 4 Expert, you are no longer just riding; you are amplifying what’s possible.

The 3.1 motor isn’t just powerful; it’s intelligent. Engineered for maximum ride efficiency, this motor uses a 27:1 gear ratio to operate at higher, more effective RPMs. This keeps performance smooth and battery use optimized. Paired with a high-capacity 840Wh battery, the system delivers sustained assistance for extended rides, even on aggressive terrain. The upgraded electrical system increases voltage to reduce current draw, cutting down on energy loss through resistance in the wiring. This all adds up to the best range-to-weight ratio in the e-MTB market. You’ll ride farther, climb higher, and explore more—all without compromise.

But raw power is only part of the story. The Levo 4 Expert is engineered with Direct Current Injection technology and advanced torque sensors that make power delivery feel incredibly natural. Whether you’re navigating rocky ascents, railing corners, or hammering down descents, the motor reads your input with pinpoint accuracy and adjusts in real time to provide just the right boost. It’s a symbiotic interaction that enhances your performance while letting you stay connected to the trail. It feels less like you’re riding a machine and more like the bike is an extension of your body.

Durability and quiet operation were also top priorities in the 3.1 motor’s design. CoreCoat winding encapsulation boosts heat dissipation, keeping the system cool during long, high-output efforts. The full-metal internal gears are twice the size of previous generations, reducing vulnerability to heat-related deformation while improving mechanical consistency. These gears also feature HardDrive surface treatment for a smoother, more durable finish that extends the life of the system and reduces noise. Additionally, the motor is decoupled from the driveside housing to minimize structural vibrations, resulting in an exceptionally quiet and refined ride feel.

Controlling all this performance is the MasterMind T3 Display System—a sleek, 2.2-inch high-resolution color screen that serves as your digital dashboard. Fully customizable via the Specialized app, this display puts motor settings, ride metrics, assist levels, range estimates, and system diagnostics right at your fingertips. Whether you're fine-tuning your power delivery or just checking your battery status, MasterMind gives you intuitive control and clear insights. The system is paired with a 4-amp charger, allowing for fast, safe battery replenishment between rides.

Supporting the powerful drivetrain is the newly designed Levo 4 frame, built from FACT 11m carbon with a refined rear-end and carbon shock extension. The geometry is adaptable, the rear suspension provides 150mm of travel, and the frame is SRAM UDH compatible with 12x148mm dropouts for futureproof drivetrain flexibility. The side-entry battery compartment ensures sleek integration without compromising ease of access, while internal SWAT storage in the downtube adds practical utility for tools and small essentials. Every bearing pivot uses sealed cartridges for smooth performance and long-lasting reliability.

The suspension platform is trail-optimized with a FOX 38 Performance Elite fork in the front delivering 160mm of travel through a GRIP X2 damper. It offers highly tunable performance with adjustments for high- and low-speed rebound and compression. In the rear, the FOX FLOAT X Performance Elite shock features Specialized's GENIE technology and Ride Dynamics Trail Tune, providing a wide range of settings via a 2-position lever and adjustable low-speed rebound. This combination offers confident handling and traction across all trail types, allowing you to push harder with more control.

The drivetrain is SRAM’s GX Eagle Transmission, providing 12-speed wireless shifting with seamless gear transitions even under load. The system includes the AXS POD Controller, GX derailleur, and GX cassette with a 10-52t gear range, giving you broad coverage for any elevation or terrain. A GX Flattop chain connects the drivetrain with a GX crankset featuring a 34-tooth T-Type steel chainring, 155mm crank arms, and an integrated guard. It’s built tough for aggressive riding and harmonized with the torque output of the motor.

The wheel configuration follows a mullet layout with a 29-inch front and 27.5-inch rear. This design provides the stability and rollover performance of a large front wheel with the agility and playfulness of a smaller rear. The wheels themselves are Roval Traverse Alloy rims laced to DT Swiss 370 hubs, tubeless-ready and built to withstand repeated abuse on rugged terrain. Both wheels use a 30mm internal rim width for optimal tire support and traction. Tires are Butcher GRID GRAVITY casing with GRIPTON T9 rubber, in sizes 29x2.3 in front and 27.5x2.3 in the rear. These tires deliver grip, damping, and durability for confident control in all conditions.

Practicality is further enhanced with the inclusion of Specialized’s SWAT system, offering integrated internal storage inside the downtube. This space is perfect for tools, tubes, or snacks, helping keep your pack light and your gear organized. The total bike weight comes in at 24.41 kilograms or 53 pounds, 13 ounces in size S4—a figure that reflects the bike’s full-power motor, high-capacity battery, and rugged componentry without sacrificing agility or playfulness on the trail.
