Extensive Field Testing: Evaluating the Levo SL 2 Pro's Durability and Handling
Over nearly a month of rigorous testing in British Columbia, the Specialized Turbo Levo SL 2 Pro was put through its paces on a variety of trails, including singletrack and lift-served downhill routes. This included both gentler, extended cross-country trails and more demanding, steeper sections. My personal frame choice, an S3, proved ideal for my height, offering a playful yet stable ride. The bike's adjustable pivot chip allowed for a steeper head tube angle, enhancing quick and agile handling, and slightly raising the bottom bracket for improved clearance on technical terrain. Accumulating nearly 70 miles and 17,200 feet of ascent/descent, this extensive testing provided valuable insights into its capabilities, especially when cross-referenced with other e-mountain bikes I’ve reviewed, such as the Pivot Lightweight Shuttle AM.
The Genesis of the Turbo Levo SL Series: Innovation in Lightweight E-MTBs
Introduced in 2020, the Turbo Levo SL marked Specialized's pioneering venture into lightweight, trail-oriented electric mountain bikes within its SL (Super Light) series, which also encompasses road and non-electric mountain bikes. The core philosophy behind the SL series is to deliver bikes that are lightweight, agile, and performance-driven, qualities that the Turbo Levo SL 2 embodies perfectly. While the Levo series is designed for versatile trail riding across all skill levels, the Kenevo collection caters to downhill-focused enduro enthusiasts. The Levo SL 2 distinguishes itself with its enhanced 1.2 motor, offering a 43% increase in torque and 33% more power compared to its predecessor, according to Specialized.
Lightweight "SL" Models Versus Full-Power E-Bikes: A Comparative Analysis
As the lighter counterpart to the formidable Turbo Levo 4, one of the leading full-power e-mountain bikes available, the Levo SL 2 boasts greater lightness, agility, and maneuverability. Its mixed-wheel configuration greatly facilitates downhill cornering, especially in tight turns, making it exceptionally nimble on winding trails. The reduced battery size and motor also contribute to a more natural ride feel, reminiscent of a non-electric mountain bike. However, riders should not expect the same power output as full-powered e-bikes on extended climbs; while it offers assistance, it relies more on human effort, meaning you might lag behind friends on more powerful models. In terms of cost, the Levo SL 2's pricing, ranging from $6,500 to $13,900, aligns with other lightweight trail e-MTBs on the market, such as the Norco Fluid VLT and Santa Cruz Heckler SL.
Maximizing Your Ride: Understanding Battery Performance and Range Extension
During longer excursions, I frequently utilized the 160Wh Range Extender, priced at $450, to mitigate "range anxiety." A notable observation was the distinct power surge experienced when the range extender depleted and the bike's internal battery took over. This was particularly evident during a 16.5-mile alpine ride with a 2,300-foot ascent through a dense Cedar forest; as the internal battery engaged, I felt a significant boost in power. This difference likely stems from the extender's lower capacity and current output compared to the main battery, making the power discrepancy more pronounced on steep grades. Despite this, the range extender is invaluable for robust rides, enabling longer distances and greater elevation gains. On one 2-hour, 12.5-mile route with 2,558 feet of ascent, the extender, alongside a portion of the main battery, proved essential. Specialized estimates the Levo SL's battery can deliver up to 5 hours of riding in Eco Mode.
Precision and Control: Evaluating the Levo SL 2 Pro's Shifting and Braking Systems
Across all my alpine adventures and bike park descents, the Levo SL 2 consistently delivered seamless, quiet, and dependable shifting. Each gear change felt immediate and precise. The Pro model is equipped with SRAM’s premium X0 Eagle Transmission derailleur and a 12-speed cassette, a wireless system managed by the AXS POD controller. This setup eliminates cables and housings, providing exact electronic actuation and efficient shifting even under moderate load, which enhances control on climbs. On descents, the Maven Silver brakes offered ample power without feeling overly aggressive, a distinct advantage given the intense braking requirements of varied terrain.
Suspension System Deep Dive: Aggressive Support from Shock and Fork
The Levo SL 2 Pro features a custom Fox Genie shock, built on a Fox Float X platform with a dual-stage air spring. Both air chambers are active during the initial 70% of travel, providing a sensitive response to small and medium bumps. For the remaining 30% of travel, only one smaller air chamber is active, significantly increasing the spring rate to prevent bottoming out. Setting up the suspension involved adjusting the sag to 25%. While the recommended air pressure for the fork was 130-150 psi for my weight, I set it at 150 psi. The higher-end Fox 36 Grip X2 fork offered strong support but felt overly stiff initially, requiring adjustments to the air pressure and compression damping to achieve a smoother, yet supportive, ride. Ultimately, I set the fork at 49 psi, far below the suggested range of 66-74 psi, to achieve optimal performance.
Thoughtful Design: Appreciated Details of the Levo SL 2 Pro
One often-overlooked yet critical design element of an e-mountain bike is the charging port latch, and the Levo SL 2 excels here. Its simple, durable plastic door with a secure clip is easy to operate and reliably stays shut, a significant improvement over flimsy designs found on other models, especially given its dual function for the range extender. Another highly appreciated feature is the integrated SWAT multitool within the headset, providing convenient, rattle-free access, an optimal placement among mountain bikes. The stock Bridge Expert Mimic seat also offered remarkable comfort, surpassing the design of standard seats from other brands like Pivot or Scott, thanks to its soft, adaptable material.
Areas for Improvement: Critiques and Considerations for Riders
The primary limitation I encountered was a noticeable disparity in climbing cadence when riding alongside individuals on full-powered e-bikes. Even on moderately distant rides, I found myself more breathless, while my companions maintained a conversational pace on challenging ascents. Furthermore, the connecting mechanism and lock for the range extender proved less intuitive. A local bike mechanic highlighted its fragility, warning of potential breakage and costly replacement. Riders are advised to familiarize themselves with its proper insertion to prevent damage. The range extender also offered a less potent assist on steep, abrupt climbs, becoming particularly evident when it ran out and the bike transitioned to its internal battery. As with any mountain bike, fine-tuning the shock and fork to individual rider weight and preferences takes time. The Fox 36 Grip X2 fork, in particular, required extensive adjustment beyond factory defaults to overcome its initial stiffness and achieve a comfortable, supportive feel.
Ideal Ridership: Who Benefits Most from the Specialized Turbo Levo SL 2 Pro
The reduced weight of the Specialized Turbo Levo SL 2 Pro was a significant highlight. Its lightness, especially when compared to full-powered e-mountain bikes typically weighing 48 to 54 pounds, is noticeable. This characteristic translates to a crisper rebound, better pop, and quicker acceleration when hitting jumps at the bike park. Its lighter build also simplifies lifting it onto hitch bike racks or chairlifts. Overall, this lightweight e-mountain bike is a strong contender for a diverse group of riders and trail types, offering a playful, maneuverable design well-suited for smooth and technical trails, steep climbs and descents, as well as flow trails and jump lines. It's an excellent choice for first-time electric mountain bike owners who don't require maximum power output but prioritize maintaining fitness with a traditional human-powered feel, complemented by assistance for faster travel. Additionally, its lighter stature makes it ideal for older or aging riders, or those with less upper body strength, making it easier to manage obstacles or load onto racks. While the Levo 4 is a top-tier full-powered model, the Levo SL 2 Pro stands out as one of the best lightweight e-mountain bikes for all-around trail and mountain biking, catering to both novices and seasoned riders. The lifetime Specialized warranty on its frame also adds significant value to its price point.
