Specialized Turbo Levo 4: The 2026 Spec Sheet, Straight

The Turbo Levo 4 is Specialized’s current full-power e-MTB, sold through the 2026 model year. It is a Class 1 pedal-assist trail bike (20 mph in the U.S.). Independent tests from GearJunkie, Blister, Flow Mountain Bike, and E-MOUNTAINBIKE agree on the hardware even when they argue about feel.

Motor: Specialized 3.1, developed with Brose. Standard 3.1: 101 Nm and 666 W peak. S-Works 3.1: 111 Nm and 720 W peak; Specialized’s February 2026 firmware update raised S-Works peak power to 850 W. Battery: 840Wh integrated pack, removable through a side door in the downtube. Optional 600Wh pack for weight, plus a 280Wh bottle-cage range extender (840 + 280 = 1,120Wh). Specialized quotes up to about 4.75 hours of Eco ride time with the extender for an 80 kg rider.

Chassis numbers that actually matter

Travel is 160 mm front / 150 mm rear. Wheels are mixed (mullet): 29-inch front, 27.5-inch rear. Head angle is 64.5° and is adjustable ±1°. Chainstay length and bottom-bracket height are also adjustable. Complete bikes in published weigh-ins sit around 52–53 lb (about 23.5–23.7 kg in size S4). SWAT storage is in the frame. Display is the MasterMind T3 / TCU with a bar remote.

U.S. complete-bike pricing published for 2026 spans roughly $5,800 on aluminum builds through about $13,499 for S-Works. That is not a casual purchase. It is also not a 40-pound miracle: testers repeatedly note that Specialized hid the mass in motion rather than deleting it.

Consensus from published tests: more battery and a smoother 3.1 motor, not a lighter bike.

If you want a lightweight SL motor, that is a different Specialized platform (Levo SL / Stumpjumper EVO, not Levo 4). If you want Bosch or Shimano service at a Trek or Cube dealer, look at those ecosystems. The Levo 4 is the full-power Specialized answer: 840Wh, mixed wheels, 160/150, and a motor you tune in the Mission Control app.
