Specialized Turbo Levo 4 Pro

The Specialized Turbo Levo 4 Pro is aimed at experienced trail riders who want full-power help on steep, technical climbs and enough travel to enjoy fast mixed-wheel descents, without stepping up to an S-Works. It sits just above the Turbo Levo 4 Expert, with a FACT 11m carbon chassis, the Specialized 3.1 motor and an 840Wh battery, plus a Fox 38 Performance Elite fork, Fox Float X Factory GENIE shock, wireless SRAM X0 Eagle Transmission and Roval carbon wheels.

It's the current UK model, sold as the 2026 Turbo Levo 4 Pro at an original UK RRP of £9,699.

The revised G4 Pro

The specification that defines this Pro now is the revised G4 kit: a Fox 38 Performance Elite with GRIP X2 damping, 160mm of travel and 2.4-inch Butcher GRID Gravity T9 tyres. A 2027 year sticker on a listing can still be this official 2026 bike, not a later generation.

Assistance comes from the Specialized 3.1 motor, rated at 810W peak power and 105Nm of torque. On a slow, rooted climb you can still pick a line instead of simply surviving the gradient.

The integrated 840Wh battery is sized for long trail-centre loops, and Specialized claims up to five hours' range. An optional 280 Wh range extender is there when you want extra time out, and a 600Wh internal battery is an option on the G4 platform when you would rather carry less mass on shorter rides.

In the box is a Specialized 4-amp charger. The faster Super Charger is not listed as standard equipment, so don't expect the promoted under-one-hour 0-80% charge from the unit supplied with the bike.

Frame, GENIE suspension and handling

The FACT 11m carbon frame runs 150mm of rear travel, with side-entry battery access and SWAT storage in the down tube, so a tube and multi-tool can live on the bike. A 29-inch front wheel and 160mm Fox 38 help the bike hold speed through chop; the 27.5-inch rear keeps the back end handy when you need to change line.

Specialized fits a Fox Float X Factory shock with its GENIE design to keep the rear tyre working on climbs and to control bigger hits on the way down. SRAM Maven Silver four-piston brakes are there for the same pace. Mountain Bike Rider's 1,000-mile test of the launch-build Pro still found harsher chassis and suspension feedback than expected, so this is a supportive, adjustable trail bike rather than a plush small-bump specialist.

Head angle, bottom-bracket height and chainstay length are all adjustable, so you can bias the bike towards agility, stability or clearance. The frame also accepts a fork up to 180mm, which suits a more gravity-focused set-up but changes the geometry and needs careful configuration.

S-Sizing overlaps on purpose. Around 173-180cm you can sit in S3 or S4, going shorter for a snappier ride or longer for high-speed calm. Reach runs from 435mm on the S2 to 505mm on the S5, with a 64.5-degree head angle and 77-degree seat angle across those sizes.

Living with the weight and the battery

An S4 is claimed at 23.94 kg, so roof racks, stairs and any unassisted pushing are honest parts of living with it. The 840Wh battery sits low in the frame via the side-entry design. On the bar, the 2.2-inch MasterMind TCU talks to the Specialized app for assistance tuning and system lock, and Apple Find My adds a tracking option if the bike disappears.

Watch the charge percentage rather than waiting for the motor to fade on its own. The G4 Turbo system keeps delivering full assistance close to empty, which is useful until the cutoff arrives without much warning. Replacement hangers are standard SRAM UDH parts, which is a practical plus after a rock strike on a carbon e-bike you actually ride hard.

Factory-fork bikes with the same name

The first Turbo Levo 4 Pro G4 build was listed at £10,299 and came with a Fox 38 Factory fork, 2.3-inch tyres and different handlebar rises, with the X0 AXS derailleur wired to the main battery. It's the same Levo 4 generation, so you're looking at a kit change rather than an older frame family.

Two Pro listings can disagree on kit, so the fork, tyre width and drivetrain power connection are the details that tell them apart. The £9,699 bike is the Performance Elite, 2.4-inch specification.

Buy the Pro when wireless X0 shifting, Maven brakes and carbon wheels are the details you will use every ride, and when a big battery plus established dealer support matter more than cutting the spend. For that rider, a hilly all-day loop becomes something you can finish still thinking about one more trail, instead of nursing the charge from the first climb.
