Specialized Levo 4 X vs Amflow TL Carbon: two takes on the go-anywhere e-bike

There's a new kind of electric mountain bike appearing in showrooms. It's not a pure trail weapon and not a commuter either. It's a bike you can load with a tent, a week of groceries or a laptop bag, and still take down a proper trail on the way home. Specialized calls its version Electric Overland. Amflow, the brand behind the DJI Avinox motor, calls its version an e-SUV.

The Specialized S-Works Turbo Levo 4 X and the Amflow TL Carbon both promise to do everything. But they come at the idea from opposite ends — and that's exactly what makes the comparison interesting.

Two philosophies in one sentence each

Levo 4 X is a full-power enduro-capable trail bike that learned to carry luggage. It's built on the same frame as the regular Turbo Levo 4, with 160 mm of travel up front, 150 mm at the rear, and racks that Specialized says are engineered so the bike still rides like a Levo when loaded.

TL Carbon is a comfortable all-rounder that happens to be very capable off-road. It has less travel (120/105 mm), touring-style handlebars, a kickstand, mudguards and lights in the box, and it's designed around carrying serious weight — up to 200 kg for bike, rider and luggage combined.

In other words: the Levo 4 X is a mountain bike first, and the Amflow is an adventure and everyday bike first.

Specialized S-Works Turbo Levo 4 X: a trail bike with a backpack

The heart of the Levo 4 X is the S-Works 3.1 motor with 111 Nm of torque and 850 W of peak power, fed by an 840 Wh battery. You can add an optional 280 Wh range extender for long days. Specialized quotes up to around 4.4 hours of riding range and says the smart charger takes the battery from 0 to 80% in under an hour.

The real story is the racks. Specialized developed its own patent-pending front and rear racks: the front carries 10 kg, the rear 12 kg, so 22 kg in total. The point is not just capacity — it's that the weight is held tight and low so the bike can still be ridden hard. Specialized describes this as suspended cargo control, and pairs it with its GENIE air shock tech, which is meant to make the bike feel like it has more travel than it really does.

The S-Works spec is everything you'd expect at the top of the range:

• FOX 38 Factory GRIP X2 fork (160 mm) and FOX Float X Factory shock with GENIE
• SRAM XX Eagle Transmission with AXS shifting
• SRAM Maven Ultimate four-piston brakes with 220/200 mm rotors
• Roval Traverse HD carbon wheels on DT Swiss 240 hubs, 29" front and 27.5" rear
• RockShox Reverb AXS wireless dropper, SWAT storage in the downtube
• Adjustable head angle, bottom-bracket height and chainstay length

All this costs $11,999.99 in the US, and the bike weighs 27.25 kg in size S4 including the racks. That's heavy for a trail bike but not for one that carries a weekend's worth of kit.

Amflow TL Carbon: the e-SUV with a superbike motor

Amflow launched the TL Carbon in June 2026. It uses the Avinox M2 drive unit: 110 Nm nominal, 125 Nm peak and 1,100 W peak power — more torque on paper than the S-Works Levo. Avinox's traction-control system adjusts power in real time to stop the rear wheel spinning on loose climbs.

The battery setup is flexible. An 800 Wh removable battery comes as standard (a 600 Wh version is available), and you can add a 480 Wh secondary battery for up to 1,280 Wh in total. Amflow quotes up to 172 km of range on the 800 Wh battery and up to 100 km more from the secondary pack.

The frame is full carbon and weighs just 2.9 kg; the complete bike in size M weighs 22.6 kg without accessories. Suspension is by FOX: a 120 mm AWL Sport fork and a Float Rhythm shock with 105 mm of travel. It runs 27.5" wheels as standard but takes 29" wheels front and rear.

Where the TL really differs is everyday practicality:

• Rear rack (MIK HD compatible), mudguards, kickstand, front and rear lights and pedals included; front rack optional
• Racks rated at 20 kg front and 27 kg rear, and support for a bike trailer via a special thru-axle
• Total system weight up to 200 kg, with riders up to 125 kg
• TRP electronic 10-speed derailleur with Avinox SmoothShift, which can shift without pedalling
• Apple Find My, offline GPX navigation and a heart-rate mode that adjusts assistance to keep you in a target zone

The components are more modest than the Levo's: Tektro four-piston brakes on 180 mm rotors, alloy wheels and Maxxis Crossmark II tyres. German retailer ebike24 lists the TL Carbon at €3,499 — a fraction of the S-Works price.

How they'll feel on the trail

We haven't ridden either bike yet, so this is based on the numbers and the design intent. On steep, rough descents the Levo 4 X has a clear advantage: 40 mm more fork travel, a 38 mm-stanchion FOX fork, an enduro-grade shock, big rotors and gravity-casing tyres. It's a bike designed to be ridden hard, loaded or not.

The Amflow will feel lighter and more playful at slow speed, and its motor is stronger on paper. On flowing trails, forest roads and gravel it should be very effective. But its 105 mm of rear travel, 180 mm rotors and touring tyres put a clear limit on how hard you can push it on technical descents.

How they'll feel on the road and on a tour

Here the roles flip. The TL Carbon comes ready for daily life: lights, mudguards, kickstand and an upright touring cockpit. It can carry more luggage (47 kg on racks vs 22 kg), pull a trailer, and its 1,280 Wh maximum capacity is the bigger tank. Electronic shifting that works without pedalling is genuinely useful at traffic lights.

The Levo 4 X carries less, and it's meant for faster, lighter trips — an overnighter in the mountains rather than a cross-country tour with panniers. You'd also need to add lights and mudguards for everyday commuting.

Motors and smart features

Both bikes run some of the strongest drive units on the market, but they feel different by design. Specialized tunes its motor for what it calls SuperNatural assistance: support that ramps up smoothly and stays controllable on slow, technical climbs. The company even claims its traction on tricky climbs beats the nearest competitor in controlled testing.

Avinox goes for raw numbers and features. Besides the higher torque, the M2 offers traction control, over-the-air updates, a 2-inch OLED display, wireless remotes and an app with offline route navigation. The heart-rate mode is a nice touch for fitness riders. Both bikes work with Apple Find My, which is a real plus for a bike this valuable.

Price and value

The gap is huge. For the price of one S-Works Levo 4 X you could buy three TL Carbons. But it's not a like-for-like comparison: the S-Works build carries the most expensive suspension, brakes, wheels and wireless drivetrain Specialized makes. If you like the Levo 4 X idea but not the price, look at the other Turbo Levo 4 builds in our catalog and check whether the racks are offered for your model. If you like the Amflow but want more trail performance, the Amflow PL Carbon uses the same Avinox ecosystem with more travel.
