The new frame
The new Turbo Levo is ground up redesign incorporating learnings (and exact design elements) from the Stumpjumper platform. The main differences being a downtube accommodating an integrated battery, a motor mounted in the bottom bracket, and some additional cable routing through the frame. Specialized claim that the new design achieves a stiffer bike with a weight distribution that achieves a lower centre of gravity for improved handling.
Like the Stumpjumper, the Turbo Levo is built to ride trails with 150 mm of rear suspension travel. The new bike has a longer reach while maintaining the chainstays length and keeping the centre gravity low. The head angle has also be slackened for descending confidence while the seat angle has sharpened for a good climbing position. Specialized has tuned the bike with better mid-stroke support for pushing into the bike on the descents. Also carried over from the Stumpjumper is the Flip Chip which either slackens or steepens the geometry to suit riding styles or the terrain.
The new Turbo Levo has been designed around a 29-inch wheel with a 2.6” tyre replacing the 27.5+ plus sizing on the first-generation Turbo Levo. Specialized explain that while the 6Fattie platform worked well, the designers preferred the speed, precision, and floatation of 29x2.6” wheel and tyre combination. The bike will still operate with 27.5 x 2.8” without detrimental changes to the bike’s geometry and can fit up to 3.0” tyres.
Specialized has elected to continue with 11-speed drivetrains on the new Turbo Levo. Explaining that with the electronic support, 11-speed already provides a sufficient range. Another consideration is that SRAM only supports NX 12-speed cassettes for e-bike use which would have meant using the heavier NX cassette across the range, passing on a weight penalty to the higher level bikes. A weight penalty that is also located at the rear of the bike, where it is most noticeable.
Lighter motor and larger battery
The new motor is remarkably lighter compared to the previous model. By using a specifically shaped magnesium bodied Brose motor and a unique direct-to-frame mounting system, the new S-Works frame drops 800 grams over the previous S-Works frame. Even the full aluminium bike is now lighter than the outgoing full carbon S-Works frame. Specialized are celebrating a total frame weight saving of just under two kilograms. The Turbo Levo Expert model we tested weighed 21.4 kilograms.
The new Specialized 2.1 motor is not only lighter but it is also 15% smaller allowing for a more compact frame design. The motor can provide up to 560 watts of pedal-assist and 90Nm of torque which can achieve up to 410% amplification of the riders input. Specialized promise the smoothest power delivery yet on an e-MTB with no awkward power surges for a better natural-feeling ride.
Shedding weight on a pedal assist bike means improved range. To add to this the new S-Works and Expert models boast a 40% increase in battery capacity to 700 watt-hours. The other new models will make use of a 500 watt-hour battery with the option of an aftermarket upgrade to the 700 watt-hour battery.
The custom Battery Management System regulates battery health, prevents overcharging, and monitors battery life to maximise distance. The Turbo Levo can last between one and five hours depending on the power settings. For riders with range anxiety, you can set the bike to ensure that the battery lasts for a set duration or until you reach a specified point.
Specialized’s updated Mission Control app works on Android and iOS and lets you interact with the Turbo Levo. The bike can communicate to your devices via ANT+ or Bluetooth. Through the app, you can perform tasks like monitor battery life, customise your motor settings, control range, and perform basic diagnoses. The power on button and battery indicator has been moved to a display close to the steerer on the top tube. The Expert model we tested arrived with a mode handlebar remote fitted.
Unfortunately for existing Turbo Levo owners, due to the integrated shape of the new motor and battery packs, neither are compatible as an upgrade to the first-generation Levo.

Iwan's First Ride
We had an Expert level Turbo Levo for a rainy morning in Jonkershoek. I find that Jonkers provides steep, rocky climbs to test the suspension's pedalling performance as well as a variety of single track downhill sections to get a feel for a bike on a mixture of terrain.

Specialized has really nailed the component choice on the Expert model. It did not feel like they have short-changed the spec sheet anywhere. Wide bars, a short stem, dropper seatpost, comfortable saddle and grips, good brakes with sensible rotor sizes and great suspension parts all make for a well-rounded bike that frees the rider to focus on the ride rather than riding around component shortcomings.
I preferred the 27.5+ (6Fattie) tyres and wheel combination over the 29er version on the previous model, as I felt the bigger wheels and skinny tyres did not cope well with the extra weight and speed potential on offer. The 29x2.6 combo on the new Turbo Levo, however, strikes a perfect balance between extra grip and traction while not being too spongy or wallowy when you don't get the tyre pressure perfect for every ride.
On my ride in Jonkershoek, I found the perfect pressures to be closer to what I usually ride and I did not feel that the tyres were as sensitive to pressure as the 6Fattie tyres. This is a good thing, plus tyres can take some time to get right, as too soft left the bike handling like a pool noodle and too hard had it skipping out of control with the smaller change to pressure tipping it either way. Get it right and it worked beautifully, get it wrong and you'd be in for a long day on the bike. Gone are those days!
On the practical side, 29-inch wheels mean that it is easier to find spares for tyres and tubes. Also, the 29-inch tube is less bulky than a plus size tube so easier to carry on the trails.
Other changes that I found a step in the right direction include moving the Turbo Connect Unit (On / Off switch, battery level, and mode display) to the top tube just behind the stem and the addition of a handlebar remote. The display unit used to be on the side of the top tube which made reaching it on the fly a near impossible task at speed.
The remote makes switching between the power modes much easier and being able to see which mode you are in with a quick glance is a major plus. For my riding, I've never been too worried about an integrated display unit with speed and battery details, as I can get that from my paired Garmin head unit. If you don't use a GPS unit or have one that can't pair to the bike to display vital information, then it will most likely be of greater importance to you.
The suspension performance deserves a specific mention. I climbed from the bottom of Jonkers to the top of Saaltjie with the rear shock wide open and not once did I feel like I had to bump the dial to make my journey easier or better. I really appreciate this in a place like Jonkers where you often get spat out of trails and have to ride to another spot to drop into the next piece single track. Not having to fiddle with levers or remotes every time one enters or exits single track makes for an even more enjoyable ride as you can just focus on the ride and being out on the bike.
Add how well-behaved the suspension is on downhill sections and you have yourself a riot of a ride. Riding as much single track as I could in one morning I never once thought "oh, I'm on an e-bike". The fork and shock does an excellent job of absorbing whatever the trail or rider throws at it. The lighter weight and lower centre of gravity of the new Turbo Levo further add to the 'normal' feel of the Turbo Levo.
In my previous review, I've made mention of the Mission Control app and the adjustability it offers. This should not be underestimated as it paves the way for a characteristic that sets the Turbo Levo apart from the competition: the way it delivers its power. The kick-in is incredibly smooth with a predictable ramp up. Some other e-bikes suffer from a brutal on / off feel that can catch one out and lead to nasty surprises. For example: when going around a corner and you give half a pedal to get your outside foot down. The bike will pick this up as a pedal stroke and the motor will kick in to deliver its pedal assist. When going around a berm or climbing switchbacks this can be quite nasty. Not fun. No such problem on Specialized's e-bikes.
The motor also totally disengages when you hit the 32 km/h speed limit for a resistance-free pedaling feel. I have ridden other bike where it feels like you hit a retarder making it harder to keep the unassisted momentum going above the governed limit.
Then there is the motor noise. Add a whizzing sound, brutal kick-in and retarder feel at the top end and you're quickly and constantly reminded that you are riding an e-bike - none of which is an issue on the Specialized. It is quiet (both the motor and the bike itself), smooth, and controlled.
As stated, this was the first ride and is not meant to serve as a full review. Even so, all the signs of a winning recipe are present with the solid base Specialized had to work from making things easier. Just as the competition has been closing up, Specialized stretched the Turbo Levo's legs and made it better.
I'll soon swing a leg over a couple of competitors' 2019 e-MTB models, but until then the new Turbo Levo is the best e-bike I've ridden and the closest an e-bike has come to being a genuine trail bike with pedal assist rather than an e-bike up-skilled with trail travel. The level of seamless integration and technology features of the new Turbo Levo cements it as the category benchmark.
