Specialized’s Turbo Levo SL II Comp Alloy reviewed: Chasing a new sweet spot in lightweight eMTB design

Specialized’s Turbo Levo SL II Comp Alloy is the brand’s latest bid for an affordable lightweight eMTB, boasting adjustable geometry and lively FSR suspension.

Priced at £5,250, it shares the same motor and 320Wh battery as its higher-end siblings but trades a carbon frame for M5 aluminium to bring costs down. On paper, it’s a compelling choice; however, a relatively underpowered motor, limited battery life and some cost-cutting in the spec leave room for improvement.

The Levo SL II’s claim to fame is its sophisticated, easily customisable geometry. This design, echoing the Stumpjumper EVO, allows riders to tweak head angles, bottom bracket heights and chainstay lengths to fine-tune cornering and handling. The 150mm rear travel and 160mm Fox fork serve up a plush, confident ride. In practice, it’s stable without feeling unwieldy, with ample sensitivity to small bumps and robust support on bigger hits.

Yet the 50Nm SL 1.2 motor and 320Wh battery feel underpowered compared to those offered by Bosch or Fazua in a similar category. Ascending steeper inclines or pushing to keep pace with conventional eMTBs exposes the limitations in torque. Battery life, while respectable enough for moderate rides, also falls short of leaders in the lightweight electric market.

At a glance, the SRAM NX Eagle drivetrain might appear serviceable, but its restricted gear range and less refined shifting dull the bike’s climbing prowess. Similarly, the stock SRAM Code R brakes lack the feel and power of their higher-spec counterparts, particularly on challenging trails. Meanwhile, the mid-weight GRID Trail tyre casing is prone to folding under aggressive cornering, and many riders would benefit from a longer-travel dropper post for added manoeuvrability.

Canyon’s Neuron:ONfly CF9 is a key rival, featuring Bosch’s well-received Performance Line SX motor and a more modern spec in terms of drivetrain, brakes and suspension. That power advantage makes a direct comparison less flattering for the Levo SL II, even if the Specialized’s geometry and suspension are arguably more polished for hard-charging descents.

In essence, the Turbo Levo SL II Comp Alloy offers a superbly engineered chassis, refined geometry and comfortable suspension. But the motor’s limited torque, restricted battery capacity and weaker components undermine its potential. For those seeking a spirited, lightweight eMTB and prepared to accept less power on the ups, there is plenty to love in its design. However, most riders will want to consider investing in a burlier rear tyre, a higher-spec drivetrain and possibly a range extender—or simply look elsewhere for more muscle and battery life in the same price bracket.
