Specialized's Levo 4 sets its sights on Amflow's PL

Specialized's Levo has become a go-to e-mountain bike for riders across the globe, and now in its fourth iteration, it gets more powerful, boasts a more natural delivery of that power, more adjustability, and the brand has managed to squeeze down tube storage in with its 840Wh battery. Here are all of the details.

The biggest story behind the new Levo 4 lies within its motor. On this new iteration, the new S-Works 3.1 motor knocks out 720W/111Nm. That is on the S-Works build, however. All others aren't quite as potent as they deliver 666W/101Nm, so still rather pokey. The bike is then fuelled with an 820Wh battery that can be extended up to 1,120Wh with an aftermarket range extender.
With all that power at its disposal, it needs to be controlled, and that's done through what the brand has dubbed its SuperNatural power delivery. We're told that the S-Works 3.1 motor delivers consistent support across the relevant cadence range. So if you're cranking hard on the pedals, it'll complement with more power up to the 70rpm mark, after which it'll level out with the faster you spin, claiming to 'dynamically amplify your ride'.
As you can imagine, a lot of work has gone into that motor, so it benefits from a CoreCoat winding encapsulation, which is said to better dissipate heat to improve durability and make for a quieter motor. The full metal gears are twice the size and less vulnerable to heat expansion, and they get a HardDrive surface treatment - that's all in the name of durability. There's then a decoupled driveside housing, which we're told reduces vibrations and noise.
Additionally, the new 3.1 motor promises more range through efficiencies built in. It uses a 1:27 gear ratio that spins at faster and more efficient speeds. Specialized has increased the voltage to reduce the current to further boost energy conservation.
With the Levo 4, Specialized has introduced perhaps the best-named thing we've seen for a while - the Wattage Cottage. It's a door that runs along the non-driveside of the downtube, which provides access to the bike's battery but also SWAT storage - the first time down tube storage has been found on an e-MTB. It's held in place via magnets and, if you choose to run the 600Wh battery, that'll open up more space for more storage.
Introduced on the latest Stumpjumper, the Levo 4 benefits from Spesh's Genie suspension technology. This is a shock built in collaboration with Fox that uses two air chambers, one inner and one outer. Combined with the Genie band, this grants linearity at the start of the stroke, but as the band blocks the outer chamber, it results in a progressive ramp-up. Of course, this is tunable via volume spacers.
With its recent bikes, Specialized has been all about geometry adjustment, and this bike's no different. To start, with the bike in its stock settings, an S4 frame gets a 480mm reach, a 64.5-degree head tube angle, a 77-degree seat tube angle, a 435mm chainstay and a 350mm high bottom bracket. As for the adjustments, there's +/- a degree of head angle adjustment, 9mm of chainstay adjustment and 6mm at the bottom bracket. The Levo 4 also employs a mullet wheelset.
Specialized has gone whole hog with the new Levo, even giving its charger an overhaul. Now, the new 700-watt Smart Charger claims to charge an empty bike to 80% in less than an hour. As standard, the bike comes with a 200-watt charger.
Wrapping things up are updates to the app and a new MasterMind display, and Micro Tune technology that allows for the fine-tuning of assist levels on the fly with 10% increments. Dynamic Micro Tune adjusts support when pedalling at a lower effort, but opens the tap to provide a full 100% support when hard on the pedals.
Prices start at £6,800 for the Levo 4 Comp Carbon and go up to £12,500 for the S-Works Levo 4.
