The Turbo Levo 4 is the most capable all-round eMTB most reviewers have tested in its class, but Specialized's decision to gate full motor power behind the S-Works price point and add over a kilogram versus its predecessor undercuts an otherwise benchmark-setting package.
- Motor performance: The S-Works 3.1 unit (720W / 111Nm, co-developed with Brose) draws consistent praise for smooth, natural power delivery and no limp mode before battery depletion — MBR recorded 1,633m of climbing on a single charge, topping their leaderboard.
- Power-tier controversy: Non-S-Works models are capped at 666W / 101Nm, a deliberate hardware lock that multiple reviewers — BikeRadar, E-MOUNTAINBIKE, and a 1,000-mile long-term YouTube review — flag as a significant and frustrating policy, not an engineering constraint.
- Suspension and handling: The GENIE-equipped Fox Float X rear shock earns near-universal praise for masking the bike's 23–25kg weight on trail; Singletracks called it "by far the most intuitive eMTB I've ever ridden," while one YouTube reviewer found descending composure unimpressive against the Yeti LT E and Transition Regulator CX.
- Value spread: At $13,499 / £12,499 for S-Works, multiple outlets — EMTV and The Loam Wolf included — point to the Expert at $9,499 as the smarter buy in the lineup; the long-term YouTube reviewer recommends the Comp outright.
- Weight: Every reviewer mentions it; at 55+ lbs with a range extender, it is heavier than the Gen 3 and heavier than direct rivals.
Skip if: you want full motor output without paying S-Works money, or you prioritize a lightweight, playful feel over planted, capable all-mountain performance.
- value · price
How much does the Turbo Levo 4 cost, and which trim is the best value?
The Levo 4 ranges from ~$5,799/€5,999 (alloy base) to $13,499/€14,499 (S-Works carbon). Reviewers consistently flag the Expert (~$9,499) or Comp ($6,799–$7,999) as the value sweet spots — the S-Works premium buys you a more powerful motor but little else, and one long-term reviewer recommends the Comp over the Pro as 'more comfortable and more dynamic.'
- performance
What is the real-world range on a single charge?
With the 840Wh battery in Turbo mode, expect roughly 1,280–1,633m of climbing per charge (22–45km depending on terrain and mode). MBR's range test topped their leaderboard at 1,633m in Dynamic Micro Tune mode, and BikeRadar logged 1,600m over 45km with 20% battery remaining. Adding the 280Wh range extender bumps total capacity to 1,120Wh for all-day rides.
- performance
How heavy is the Turbo Levo 4, and does the weight matter on the trail?
The S-Works carbon weighs ~23.6–23.9kg (52–53lb) without pedals in size S4; the alloy Comp is heavier at ~26kg (58lb). Reviewers largely agree the weight is noticeable on paper but well-disguised on trail thanks to the low center of gravity and GENIE suspension — though one reviewer noted hand fatigue on extended rides and another found it struggled to track straight in rough, high-speed chunk.
- components
Is the S-Works motor worth paying for, or is the standard 3.1 motor good enough?
The hardware is identical — only software separates them. The S-Works 3.1 produces 111Nm/720W while all other models are capped at 101Nm/666W (or 105Nm/810W after a software update on newer builds). BikeRadar and E-MOUNTAINBIKE both say the extra torque only makes a meaningful difference on the steepest, most technical climbs; for most riders the standard motor is 'elite tier' and the Comp or Expert represents better value.
- vs. competitors
How does the Levo 4 motor compare to Bosch CX Gen 5 and DJI Avinox?
Reviewers broadly agree the S-Works 3.1 is level-pegging with the Bosch CX Gen 5 — with the extra torque giving a slight edge on steep technical climbs — but the DJI Avinox edges it out on smoothness and power delivery. The Levo 4's motor is notably hesitant to re-engage after you stop pedaling, which some riders found frustrating on switchbacks.
- components
What are the battery options, and can I run the bike on the range extender alone?
Yes — the Levo 4 supports three batteries: 840Wh (4.4kg), 600Wh (3.2kg), and a 280Wh range extender (1.65kg) that mounts where the bottle cage sits. The 280Wh extender can power the bike entirely on its own (removing the main battery saves ~2.5kg), though max power drops to ~380W. Combining the 840Wh + extender gives 1,120Wh total; the 600Wh + extender gives 880Wh with better weight distribution.
- known issues
Are there any known reliability or quality issues to watch out for?
Reviewers disagree on severity: one YouTube long-term tester reported significant battery clunking developing within a season, and noted Roval rims so shallow that third-party Maxxis/Schwalbe tires couldn't be mounted without breaking tire levers. On the positive side, Specialized's warranty is praised for covering bearings and wheels beyond the norm. No widespread frame or motor failure reports appear in the corpus.
- use case
Is the Levo 4 a good fit if I want to do big enduro/gravity days rather than all-mountain riding?
For gravity-focused riding, the Levo 4 EVO is the better pick: it adds 180/170mm travel via a €95 conversion kit compatible with the standard carbon frame, and reviewers call it 'massive composure and confidence' on steep, rough terrain. The standard Levo 4 (160/150mm) is praised as an exceptional all-mountain bike but can feel outclassed in chunky, high-speed descents compared to longer-travel rivals like the Yeti LT E or Transition Regulator CX.
What reviewers actually said
With 111Nm and 720w of peak power, the new S-Works 3.1 motor establishes itself as one of the most powerful on the market.
Travel grows to 180 mm at the front and 170 mm at the rear, giving you 20 mm more reserves at both ends.
Its M5 Premium Alloy frame, while not carbon, demonstrates excellent torsional rigidity, translating into precise cornering and surprising responsiveness for an electric mountain bike.
At €14,499, the top-spec S-Works version of the Levo 4 isn't exactly a bargain – in fact, it costs around €500 more than the already sinfully-expensive Levo 3 counterpart. And at 23.7 kg in size S4, it's also over a kilogram heavier than its predecessor.
The power delivered by the S-Works drive unit we tested placed it solidly up at the front of the pack, coming close to rivalling the DJI Avinox system.
The Specialized 3.1 drive unit is a 3.2 kg (7 lbs) drive unit producing 810W peak power and 105Nm maximum torque.
The Specialized Turbo Levo 4 can run off three different battery sizes: 840Wh, 600Wh, and 280Wh.
I managed 1,633m of climbing in the 100/100 Dynamic Micro Tune mode, which gives it the best range of any bike I've tested.
