The Specialized Turbo Levo Comp Alloy continues its reign as our top pick for the fourth consecutive year. Our lead tester, Joshua Hutchens, sums it up best: “It’s just the most fun to ride.” A standout feature is its adjustable geometry, offering six distinct configurations through headset cups and chainstay flip chips. The head tube angle can be altered from 65.5 to 63.5 degrees in full-degree increments, while the bottom bracket height adjusts by 7mm. Joshua highlights, “This unprecedented adjustability allows riders to tailor the bike to their specific riding style, terrain, and preferences, elevating the Levo’s versatility significantly.”
The move to mixed wheel sizes enhances maneuverability in the rear and provides better clearance on steep trails. The 700Wh battery delivers an impressive 33.1-mile range in our tests, surpassed only by the Canyon Spectral:ON CF 8 with its larger 900Wh battery. The motor provides substantial torque with customizable support settings. The system’s refinement and integration are top-notch. The Comp Alloy model offers a functional and capable component package, providing excellent value, especially with current discounts bringing the price down. While the Ari Wire Peak 2.0 Comp is more affordable, it compromises significantly on performance.
Despite its many positives, the Turbo Levo Comp isn’t without minor drawbacks. A handlebar display might be a welcome addition, although the top tube TCU provides essential data while maintaining a clean cockpit. The SRAM Code R brakes on our test bike were adequate but exhibited a spongy feel during extended descents due to heat build-up. While we appreciate Specialized tires, the GRID Trail casings aren’t ideal for the bike’s weight and aggressive riding potential. Nevertheless, the Specialized remains a test team favorite, praised for its adjustable geometry, well-rounded performance, and impressive range and efficiency. Many of our testers, owning various Levo models, attest to its incredible value. While motor replacements have occurred, the warranty process has been consistently positive.

The Canyon Spectral:ON CF 8 impressed us with its massive 900Wh battery, setting a new benchmark for range in our tests. Featuring mixed wheel sizes, 155/150mm of travel, and a modern trail geometry, this full carbon frame e-MTB is designed for serious adventures. Chris McNamara noted, “I could ride nearly 10,000 vertical feet in eco mode, well beyond any E-MTB I have tested.” The Shimano EP8 motor is strategically angled to accommodate the large battery and maintain a low center of gravity. The result is a surprisingly maneuverable and balanced bike, defying its heavier weight. It provides stable handling and ample travel for challenging terrain while remaining agile on mellower trails. Its trail geometry strikes a balance between climbing efficiency, agility, and overall versatility. Canyon’s direct-to-consumer model allows them to offer this bike at a highly competitive price, making it an exceptional value proposition for a carbon e-MTB with this spec and battery size.
The Spectral:ON CF 8 isn’t perfect. The large 900Wh battery, while a major selling point, results in a bulge below the bottom bracket, reducing ground clearance, especially with the already low bottom bracket height. While the Fox 36 Rhythm fork is generally capable, the bike’s weight could be better supported by a burlier Fox 38. We experienced some flex in the 36 fork under hard braking and in rough terrain. The Maxxis Minion DHR II and Assegai tire combo is excellent, but the EXO+ and EXO casings are not robust enough for the Spectral:ON’s weight and aggressive riding capabilities. Upgrading tires is a relatively inexpensive fix, but premature tire or rim damage is disappointing. Despite these minor drawbacks, the Spectral:ON CF 8 is a top contender in the electric mountain bike market, particularly for riders prioritizing range and value.

Aventon, primarily known for urban and commuter bikes, enters the e-mountain bike arena with the Ramblas, powered by their new A100 motor. The Ramblas delivers an exciting package at a groundbreaking price point. Its component spec includes a RockShox 35 Silver fork, SRAM NX Eagle drivetrain, SRAM DB8 brakes, a dropper post, and Maxxis tires—components typically found on much pricier bikes. A removable 708Wh battery powers the high-torque motor. This is the most affordable full-suspension e-MTB we’ve tested, and remarkably, also the most powerful, registering over 26Nm of torque at the rear wheel in our dynamometer tests. Lead tester Joshua states, “Most E-MTB models climb at about the same rate in turbo. The Ramblas just smoked them all.”
The aluminum frame, 29″ wheels, 130mm coil-sprung fork, and slightly conservative modern geometry contribute to the Ramblas’ versatility. Its impressive spec and performance make it more than just the sum of its parts. It’s incredibly fun and powerful, often outperforming other e-bikes in cross-country scenarios. Aventon’s direct-to-consumer model translates to significant cost savings. With four frame sizes, including a small size with 27.5″ wheels, the Ramblas caters to a broad range of riders.
However, the Ramblas ride quality is less refined. The non-adjustable fork and non-tubeless compatible rims compromise comfort, potentially deterring aggressive trail riders. Its versatility extends beyond trails, though. Equipped with integrated tail lights, a bright headlight, and kickstand mount points, it appeals to riders seeking a versatile e-bike with a mountain bike disposition for varied uses. Weighing in at 54 lbs, it’s not light, but the powerful motor compensates for the weight. In our range test, the Ramblas covered 30.1 miles with nearly 6,000 feet of climbing on a single charge. Powerful, capable, and exceptionally priced, the Ramblas is a standout value in the e-MTB market.

The redesigned Specialized Turbo Levo SL Comp redefines the lightweight e-MTB category. Built around Specialized’s SL 1.2 motor and a 320Wh battery, it offers a more natural riding experience, blending the feel of a traditional trail bike with electric assist. Its 50Nm motor delivers less torque than the standard Levo’s 90Nm, focusing instead on subtle assistance and reduced weight. At just over 40 pounds, it’s significantly lighter than competitors like the Trek Fuel EXe 8 GX AXS Transmission, making it a prime option for riders considering mid-power e-MTBs. The Levo SL stands out with its lighter weight, exceptional adjustability, and user-friendly interface.
Its downhill performance is impressive; the adjustable headtube angle enhances high-speed stability, and the short 432mm chainstays contribute to its playful, agile feel. The lighter weight makes it sprightly in technical terrain, unlike heavier e-MTBs. Power delivery is natural, enhancing the rider’s input without overpowering the experience, allowing for a more athletic climbing feel. While its power output test results are lower, this is intentional, providing assist while still demanding rider engagement.
The FACT 11M carbon frame and Fox suspension offer a comfortable and responsive ride. The SRAM drivetrain provides reliable performance. While the higher-end Transmission drivetrain offers more precision, the cost increase isn’t necessarily justified. This build represents a performance sweet spot for the price. Specialized also offers an alloy version, but the weight savings of the carbon model are significant for the minimal price difference. We also tested it with a 29″ rear wheel, which improved efficiency but reduced some of its playful character. Testers appreciated the bike’s lightweight feel, even riding it without power and still enjoying a great trail experience.

Choosing the Best Electric Mountain Bike: A Buyer’s Guide
Selecting the ideal e-mountain bike can be challenging. Adding a motor introduces more complexity. This guide highlights key considerations to simplify your buying process.
Full Power vs. Lightweight E-MTB
Full-power e-MTBs feature larger motors (700-900Wh range, 80-90Nm torque) and are ideal for long rides, steep climbs, or riders seeking maximum assistance.
Lightweight e-MTBs offer subtle pedal assist with smaller batteries (320-430Wh), prioritizing handling and agility. Their streamlined design resembles acoustic bikes, delivering a more natural ride feel.
Consider your riding style and needs. Do you prioritize maximum range and power for challenging terrain, or a more natural, agile ride? Your typical riding habits and trails will guide your choice.
Choosing between lightweight and full-power e-mountain bikes
Image: Comparing lightweight vs full-power e-mountain bikes to determine the best type for your riding style.
Frame Material: Alloy vs. Carbon
Like traditional mountain bikes, e-MTBs come in alloy and carbon frames. Carbon frames offer lighter weight and vibration damping, crucial for e-MTBs. Carbon reduces significant weight in the downtube and motor area. However, carbon frames are more expensive. For weight-conscious riders, carbon is worthwhile. For others, alloy is more affordable and durable against scratches and scrapes.
Wheel Size: 29″ vs. Mixed (Mullet)
Most e-MTBs use 29″ wheels for stability and rollover capability. Some opt for “mullet” setups (29″ front, 27.5″ rear). Wheel size choice depends on the bike model, as not all offer both options. Some bikes feature flip chips to accommodate different rear wheel sizes. Mullet setups enhance agility and playfulness due to shorter chainstays. Decide based on preference: stability and rollover (29″) vs. maneuverability (mullet).
Choosing the right wheel size for your e-mountain bike

Suspension Travel: How Much Do You Need?
Suspension travel defines a bike’s riding capabilities. Under 140mm travel is ideal for cross-country and trail riding. 140-160mm is the most popular for e-MTBs, offering a balance. Over 160mm is for downhill-focused riding. Most e-MTBs fall into the all-mountain category (140-160mm), balancing uphill and downhill performance. Well-designed e-MTBs can handle more travel without compromising uphill efficiency due to motor assist.

Understanding E-Bike Classifications
Electric bikes vary in classifications. Most e-MTBs are Class 1: pedal-assist only, with power delivered while pedaling, limited to 20 mph in the US. These resemble mountain bikes but integrate batteries and motors. The motor, usually near the bottom bracket, provides pedal support in varying degrees. Most systems offer customizable support settings.
We tested full-suspension all-mountain/trail models with similar travel, geometry, and wheel/tire sizes. E-bikes are heavier (around 50 lbs, ~20 lbs heavier than non-e-bikes) due to batteries and motors, making them harder to ride without assist. The Trek Fuel EXe, a lighter model, weighs just over 45 lbs.
E-MTBs are legal in many US areas, especially on motorized trails. Always check local regulations before riding. We tested on OHV trails near Lake Tahoe, where e-MTBs are permitted.
E-bikes have more components prone to failure (motor, battery, controls, wiring). Research warranties and buy from local dealers for support.
