Specialized has lowered the price of its latest Turbo Levo SL by introducing a new alloy model, the brand\u2019s first lightweight electric mountain bike with an aluminium frame.<\/p>

The frame shares the silhouette, motor and battery of its carbon sibling<\/a>, but Specialized has significantly dropped the price \u2013 in exchange for a weight penalty.<\/p>

Just one model is available, weighing a claimed 20.2kg \/ 44.85lb in an S4 size and costing \u00a35,250. International pricing and availability outside the UK are yet to be confirmed.<\/p>

Like the carbon Turbo Levo SL, the alloy bike is sold exclusively as a mixed-wheel mullet bike<\/a>, with 29in front and 27.5in rear wheels.<\/p>

No extra parts, other than a 29in rear wheel, are needed if you wish to run a full 29er setup<\/a>, however.<\/p>

The bike gets the same adjustable geometry, with both head angle and bottom bracket height adjustable.<\/p><\/div><\/div>

Five things you need to know about the Specialized Levo SL Alloy<\/h3>
Alloy frame helps drop price to \u00a35,250 (international pricing TBC)<\/li>
Same motor and battery as more expensive carbon model<\/li>
Sold as a mixed wheel-size mullet bike, but can be converted to full 29er with no extra frame parts<\/li>
Range-extender battery is included in the price<\/li>
Retains adjustable geometry \u2013 head angle and bottom bracket height can be adjusted; longer chainstay length for 29in rear wheel<\/li><\/ul><\/div><\/div>
Heavier bike is lighter on your bank balance, but not on features<\/h2>

The switch to an aluminium frame<\/a> and cheaper components means this is the cheapest lightweight electric mountain bike<\/a> Specialized offers.<\/p>
It saves \u00a31,750 over the cheapest Levo SL Comp Carbon<\/a>, but weighs nearly 3kg \/ 6.6lb more than the range-topping, but significantly more expensive, S-Works model.<\/p>
While the switch to an aluminium construction from carbon helps cut costs, it hasn\u2019t come at the expense of frame features or the motor and battery.<\/p>

The Levo SL Alloy has been given the same Turbo SL 1.2 motor as its carbon counterpart. This delivers 50Nm of torque and peak power of 320W.<\/p>
This isn\u2019t a match for Bosch\u2019s Performance Line SX<\/a>, but it aligns closely with TQ\u2019s HPR 50 and Fazua\u2019s Ride 60 electric bike motors<\/a>.<\/p>
The non-removable 320Wh battery also carries over and the 180Wh range extender, which was optional on the carbon bike, is included in the price.<\/p>
Like the more expensive carbon models, the Levo SL Alloy uses the same MasterMind TCU display, integrated into the top tube.<\/p>

This displays modes, battery capacity, speed, time, distance, elevation metrics and estimated range \u2013 and can also show your heart rate if connected to a heart rate monitor<\/a> via ANT+ or Bluetooth.<\/p>
Switching between the five modes\u00a0\u2013 Eco, Trail, Turbo, Walk and Micro Tune \u2013 is controlled by a handlebar-mounted remote.<\/p>
Using Specialized\u2019s Mission Control app, each power mode can have its support, peak power output and acceleration response tuned.<\/p>
Updates to the system can be downloaded and installed \u2018over the air\u2019 through Bluetooth via the app; there\u2019s no need to plug the bike in to install the latest updates.<\/p><\/div><\/div>
Different material, same geometry<\/h2>

The alloy frame not only shares the carbon version’s silhouette, but also the majority of its geometry adjustment and suspension kinematics.<\/p>
The Levo SL Alloy retains the brand\u2019s S-Sizing concept and, as a result, is available in six sizes \u2013 S1 to S6.<\/p>
Specialized claims this enables riders to choose their frame size based on their preferred reach, rather than the seat-tube length.<\/p>
Riders wanting a more agile bike can size down and choose a shorter reach number, whereas those looking for more stability can pick a bigger frame, while still being able to use a long-travel dropper seatpost<\/a>. <\/p>
It means most riders should have two, or possibly three, frame sizes to choose from.<\/p>

The S1 is unique in the size range because it features a 150mm-travel fork and slightly reduced rear travel of 144mm. All other sizes feature 160mm forks and 150mm of rear-wheel travel<\/a>.<\/p>
Reach numbers range from 405mm on the S1 size to 525mm on the S6. <\/p>
The steps between sizes get bigger as you go up the range, increasing 20mm from S2 to S3 and 25mm from S3 through to S5, before a 30mm jump from S5 to S6.<\/p>
The head angle on the Levo SL Alloy is a shade steeper than the carbon bike at 64.6 degrees, as opposed to 64.5 degrees, while the seat angle is the same at a not-so-steep 75.8 degrees on all sizes.<\/p>
Chainstays are also the same across all sizes, at 432mm with the stock mullet-wheel setup, and jump by 10mm if switched to full 29er mode.<\/p>

Bottom-bracket drop is -29mm on sizes S2 through S6, with the S1 having slightly more at -34mm on account of its shorter fork.<\/p>
If you\u2019re not a fan of these numbers, the Levo SL Alloy shares the same geometry adjustment as the carbon bike.<\/p>
The head angle can be adjusted by one degree in either direction with the included headset cups.<\/p>
A flip chip<\/a> in the shock yoke drops the bottom bracket by 5mm and steepens the head and seat tube angles by approximately 0.5 degrees.<\/p>
The bike features full 29in-wheel compatibility. This is taken care of by another flip chip in the Horst pivot on the chainstay.<\/p>
Switching to the 29in rear-wheel setting increases the chainstay length by 10mm to 442mm.<\/p>
