Build Your Ultimate Levo 4
The Specialized S-Works Turbo Levo 4 Frameset 2026 gives you the top-level carbon chassis, most powerful Levo motor and a huge 900Wh battery, ready to build with your choice of fork, drivetrain, brakes, wheels and cockpit.
The S-Works 3.1 motor delivers up to 850W of peak power and 111Nm of torque, while the FACT 11m carbon frame provides 150mm of rear-wheel travel through a RockShox Super Deluxe Ultimate shock with GENIE. Adjustable geometry and mixed-wheel compatibility give you plenty of scope to build the bike around your trails and riding style.
Please note: This is a frameset, not a complete bike. It includes the frame, rear shock, motor, battery, display, charger, crankset and chainring. The fork, wheels, drivetrain, brakes, cockpit, saddle and seatpost must be purchased separately.
Where Super Meets Natural
The S-Works Turbo Levo 4 combines serious motor output with the controlled delivery needed on technical trails. Rather than simply hitting the rear wheel with full power, the system responds smoothly to your input, helping the tyre maintain traction on steep, loose and awkward climbs.
Motor support can be adjusted through the Specialized app, while Micro Tune lets you make smaller changes during a ride. This makes it easier to balance assistance, grip and battery use as the trail changes.
S-Works Power and Torque
The S-Works 3.1 motor produces up to 850W of peak power and 111Nm of torque. It is Specialized’s highest-output Levo motor, giving the bike the muscle needed for sustained climbing and demanding technical terrain.
Just as importantly, its power delivery remains predictable at low speed. That control makes a real difference when you are picking a line through roots, rocks or tight climbing turns where too much wheelspin can stop you in your tracks.
900Wh Battery and Extendable Range
The integrated 900Wh battery provides plenty of capacity for long trail rides. Specialized claims up to 4.63 hours of riding time when the bike is used with the optional 280Wh Range Extender, based on Eco mode, an 80kg rider and significant elevation gain.
Adding the Range Extender increases the total available capacity to 1,180Wh. View the Specialized Levo 4 Full Power Range Extender.
Actual riding time will depend on the assistance mode, terrain, elevation, rider weight, weather, tyre choice and overall bike setup.
FACT 11m Carbon Chassis
The FACT 11m carbon frame and carbon suspension link deliver the stiffness and control expected from an S-Works chassis. The frame provides 150mm of rear-wheel travel and can accommodate forks with up to 180mm of travel.
Head angle, bottom-bracket height and chainstay length can all be adjusted. This lets you fine-tune the handling for anything from balanced everyday trail riding to steeper and more aggressive terrain.
RockShox Ultimate Suspension with GENIE
The included RockShox Super Deluxe Ultimate GENIE shock uses a tunable dual-air-spring system to combine small-bump grip with strong mid-stroke support and better resistance to harsh bottom-outs.
Its RC2T damper provides separate high-speed and low-speed compression adjustment along with rebound control. That gives experienced riders plenty of scope to dial in the suspension around their weight, riding pace and local terrain.
MasterMind Control
The integrated MasterMind TCU uses a 2.2-inch high-resolution display to keep ride and system information easy to read. It works with the Specialized app for motor tuning, ride recording and system management, and also supports Apple Find My.
The included Specialized 12A smart charger provides Standard, Fast, Eco and charge-to-80% modes. Under suitable conditions, Fast mode can charge the battery from zero to 80% in under an hour.
SWAT E-MTB Storage
Weather-resistant SWAT storage inside the downtube gives you somewhere to carry a tube, tools and other trail essentials without loading up your pockets. It keeps the finished build tidy and makes it easier to leave the house with the basics already on the bike.
Adjustable Trail Geometry
The Levo 4 gives you meaningful geometry adjustment rather than one fixed setup. Head angle, bottom-bracket height and chainstay length can be altered to suit the terrain and the way you want the bike to handle.
The standard position is the sensible starting point for most riders. From there, the bike can be set up for more high-speed stability, extra pedal clearance or a more agile feel through tighter trails.
S-Sizing and Mixed Wheels
Specialized S-Sizing lets you choose a frame according to both your height and preferred handling. A smaller size will generally feel easier to move around, while sizing up provides more reach and high-speed stability.
The frame is designed around a 29-inch front wheel and 27.5-inch rear wheel. This mixed-wheel layout combines good front-wheel rollover with a rear end that is easier to place through tight corners and steeper sections.

Who Is It For?
The S-Works Turbo Levo 4 Frameset is for experienced riders who want to choose every part of their build. It makes sense if you already own suitable components, have a particular suspension or drivetrain setup in mind or want a Levo built specifically around your terrain.
If you would rather have a bike that is ready to ride without sourcing the remaining parts, one of the complete Turbo Levo 4 models will be the more straightforward choice.
Our Thoughts
This frameset gives you the important parts of Specialized’s top Levo platform without locking you into a factory component package. The S-Works motor offers noticeably more power and torque than the standard 3.1 unit, while the 900Wh battery is well suited to riders planning long days with plenty of climbing.
The real appeal is being able to build the bike properly for your terrain. Whether you want a balanced 160mm trail bike or a heavier-duty setup with up to 180mm of fork travel, the adjustable chassis and Super Deluxe Ultimate GENIE shock provide an excellent base to work from.
