Specialized Turbo Levo R Expert vs. Levo 4 Expert: Which E-MTB Is Right for You?

With the Turbo Levo R, Specialized expands its full-power E-MTB range with a lightweight, agile trail bike. But does it actually feel more lively and direct than the Turbo Levo 4? How does it perform when the terrain gets more demanding? How big are the differences between the two bikes in practice? And which model is right for whom?

To find out, our colleague Berno put the Levo R Expert through an extensive long-term test. At bike-components, he is our in-house specialist for Specialized E-MTBs: he already spent plenty of time in the saddle for our Turbo Levo 4 comparison test, and privately he rides a Specialized Turbo Levo 3 Alloy LTD. Berno therefore knows the differences between these bikes very well and shares the results of his real-world test here.

Berno, you got to test another bike! For anyone who doesn't know your background yet: How long have you been riding MTB? Which bikes do you ride privately? And what do you do at bc when you're not testing Specialized E-MTBs?

Yes, I was absolutely delighted. I've been mountain biking for many years and privately ride a Forbidden Druid as my non-electric bike and a Specialized Turbo Levo 3 Alloy LTD. My home trails are short and steep low-mountain trails – sometimes rooty, sometimes rocky, sometimes flowy. If I'm short on time or want to extend my riding radius, I take the E-MTB; otherwise, I'm just as happy riding my non-electric bike.

I've been working at bike-components in online marketing since January 2024 and lead the Customer Engagement team. Together, we continuously develop the customer experience in the bc shop and make sure our customers enjoy a simple, well-designed and pleasant shopping experience.

The Turbo Levo R in the real-world test

How does the Levo R ride on the trail? Where are the differences compared with the Levo 4, uphill and downhill?

The Turbo Levo R really impressed me – it's an incredibly fun bike. It rides exactly as Specialized promises: lighter, more direct and more agile than the Levo 4. That suits my active riding style perfectly. Instead of simply ploughing over small roots, the bike encourages me to unweight the wheels briefly or actively use small trail features. That makes it feel very playful. It also gives me more feedback from the ground. That's exactly what makes it so appealing to me. At times, the Levo R feels more like a non-electric bike than a full-power E-MTB.

My home trails don't require a long-travel trail bike, and a 29er with less travel is almost made for them. They start out steeper and more technical, then become flatter and rootier. That's exactly where the Levo R plays to its strengths. With an active riding style and clean line choice, you can get through the demanding sections very well. On flatter, rooty sections, the 29er carries an enormous amount of speed, feels playful on the trail and gets hung up less between roots. There was no noticeable pedal kickback and I even managed to set a few new personal best times.

What surprised me was how late the Levo R reaches its limits. Of course, at high speeds and on rough trails, you notice the lower weight, shorter travel and slightly smaller reserves compared with the Levo 4. In return, the bike rewards an active riding style with huge amounts of fun. Anyone who mainly rides in low mountain ranges, likes to actively work the bike and deliberately play with the trail will probably find the Levo R more suitable than the Levo 4.

Uphill, the Levo R rides with the same confidence you'd expect, and I always had plenty of traction. Thanks to the lower weight, it feels even more lively, while the slightly steeper head angle and more aggressive riding position make it easier to handle in tight switchbacks.

You're 1.92 metres tall: Do you prefer the mullet setup of the Turbo Levo 4 or the 29-inch setup of the Levo R? Which size Levo R did you ride?

For my height and my home trails, the Levo R's full-29 concept really works in my favour. Especially on flatter, rooty sections, the larger rear wheel noticeably rolls better and carries more speed. Important to know: the smallest size (S1) of the Turbo Levo R comes with a mullet setup featuring 29 inches at the front and 27.5 inches at the rear.

I'm between sizes S4 and S5 and rode the Levo R in S4 and the Levo 4 in S5. That means the comparison isn't completely like-for-like: the size difference emphasises the more agile, poppy feel of the Levo R and the composure and stability of the Levo 4. I rode both bikes with a neutral head angle. On the Levo R, I chose the lower bottom bracket position and long chainstays, while on the Levo 4 I used the higher bottom bracket position and short chainstays. This reduced the difference in wheelbase between the two bikes slightly, although it remains noticeable.

If I were to buy the Levo R – which I'm definitely considering – I'd choose size S5 with the short chainstay setting. That would give me a little more composure without losing the playful character of the bike. The front end would also be slightly higher, which would suit both my height and my preferred riding position.

For anyone unfamiliar with Specialized S-Sizing: unlike traditional frame sizing, Specialized trail bike sizing isn't based solely on rider height, but also on the desired handling characteristics. Smaller sizes provide more agility, while larger sizes offer more stability. S-Sizing ranges from S1 to S6 and covers rider heights from around 150 to 203 centimetres.

The in-house motor: Specialized 3.1

What's new with the Specialized 3.1 motor? How do you like the update with even more power?

Since our Levo 4 test, Specialized has not only given the 3.1 motor more peak power and torque via an over-the-air update, but has also improved the software in several other areas.

I was particularly impressed by the new Dynamic Micro-Tune (1xYou). The motor reacts noticeably more sensitively to my input and dynamically adjusts the assistance accordingly. This makes the motor even easier to control precisely. At the same time, motor overrun – how long the motor continues providing assistance after a pedal input – has been optimised. This allows me to give short, deliberate pedal inputs without the motor continuing to assist longer than I want. Both points make a real difference for me on technical trails, because I can use the assistance more deliberately and tackle edges or steps with more control.

In addition, the motor now reduces assistance more gradually as I approach the legally permitted support limit. This makes the transition feel less abrupt. Also new are three different walk modes, allowing me to fine-tune the walk assistance to the terrain and my own preferences.

Overall, I'd say the additional power isn't the highlight of the update for me – it's the more precise ride feel as a whole. So anyone who already owns a Turbo Levo 4 or R should definitely install the update. The improvements are noticeable on the trail and make riding a full-power E-MTB feel even more natural.

Do you customise your motor setup via the Specialized app? What do you adjust and why?

During my test, I stuck with the factory settings. If I decided to buy the bike, I would tune the Trail mode to be slightly more powerful and use Turbo mode exclusively for longer, steeper climbs.

Especially on descents, I ride almost entirely in Trail mode because the overrun in Turbo mode feels a little too imprecise when I use short pedal inputs on technical trails. With a customised setup, I could use Trail mode for most of my rides and only activate Turbo when I really need maximum assistance uphill.

I would also set Eco mode a little stronger. I barely used it during the test, except on one big ride of around 50 kilometres and 1,700 metres of climbing in the Harz. At the end, I still had more than 25 percent battery left, so there would have been room for a little more assistance.

How do you like the remote and display?

Specialized continues with its concept of a display integrated into the top tube. As on the Levo 4, it's large enough, sharp and high-contrast. The same handlebar remote is also used. In particular, the walk-assist button on the new remote is noticeably easier to reach with your thumb than on the old system. When things get steep and rough uphill, that gives you more control. I do have one small criticism, though: several times I accidentally pressed the upper button when changing assistance levels or even with my knee. That changes the information shown on the display. It's not a major issue, but it can occasionally be a little annoying.

Specialized Turbo Levo R – Conclusion

How do you like the Levo R and what's your conclusion?

The Levo R doesn't replace the Turbo Levo 4. Instead, it expands the range with a sportier and more direct alternative for riders who prefer less suspension travel and weight in favour of more agile handling.

Personally, the Levo R really impressed me. The lower weight and more playful geometry suit my riding style and terrain perfectly. Its handling comes closer to that of a non-electric trail bike, it carries plenty of speed, yet it still feels more planted and composed on the trail in typical E-MTB fashion.
More than anything, the Levo R showed me how far full-power E-MTBs have evolved. Full-power no longer automatically means huge suspension travel and a weight somewhere in the mid-20-kilo range. Instead, we're seeing increasingly specialised concepts within this category: from downhill bikes with an “integrated shuttle” to aggressive trail/enduro bikes and lightweight, agile downcountry bikes. I find that development really exciting.

Who is the Turbo Levo R for? Who should buy the Turbo Levo 4?

If you're looking for a playful, direct trail bike, mainly ride flowier trails or want an E-MTB that feels closer to a non-electric bike, you'll probably be happier with the Levo R. It rolls more easily, carries a lot of speed on flatter trails and responds more sensitively to rider input. It also performs extremely well on technically demanding trails – provided you have good riding skills, choose clean lines and perhaps upgrade the tyres and brakes. Of course, you need to be aware that it offers fewer reserves and gives you more feedback from the ground.

The Turbo Levo 4, on the other hand, is aimed at riders looking for a classic full-power E-MTB with more suspension travel and greater reserves. Anyone who frequently rides demanding trails, alpine terrain or bike parks will benefit from the more downhill-oriented geometry and spec of the Levo 4. It feels more composed and forgiving, although it also requires a little more body input to move the bike around or build speed when the trail becomes flatter and flowier.

By the way: if your focus is clearly on demanding enduro trails, bike park sessions without lifts or shuttles and maximum downhill performance, it's also worth taking a look at the Turbo Levo Evo. With 180 millimetres of travel at the front, 170 millimetres at the rear and correspondingly robust components, it's designed for hard-hitting trails.
