Every so often, an electric mountain bike launch lands with enough force to shift the entire category. For 2027, that bike is the Amflow PX Carbon. With a completely redesigned chassis, a next‑generation battery system and the debut of the Avinox M2S motor, the PX Carbon series isn’t just an update — it’s a statement of intent.
This is the lightest, quietest and most powerful full‑power e‑MTB Amflow has built, and it’s already being talked about as one of the most important electric mountain bike launches of the year.
Launch highlights:
- 150 Nm peak torque (23% more than the previous gen)
- 1500 W peak power with a tuneable 10–60 sec Boost Mode
- 130 Nm sustained torque for long, steep climbs
- 3.18 kg battery weight — over 1 kg lighter than some rivals
- 2.59kg M2S Drive Unit
- 45 dB noise output — one of the quietest full‑power motors
- Dual‑engagement helical gears for smoother pickup
- More cooling fins for better heat management
The M2S is arguably the most powerful lightweight full‑power e‑MTB motor on the market.
New 700 Wh Battery With Bigger Real‑World Range
Amflow’s redesigned battery platform delivers more range from a smaller, lighter unit.
What’s new:
- 21% smaller than the old 800 Wh battery
- 20% higher energy density — industry‑leading
- Up to 144 km range (test conditions)
- Faster charging: PX Carbon: 80% in 1 hr 16 min
- Reduced drivetrain friction thanks to new SRAM tech
You get more range, less weight and faster charging — a rare combination in full‑power e‑MTBs
New Display, Navigation & Connectivity
Touchscreen Control System
The PX introduces Amflow’s smartest cockpit yet, centred around a responsive touchscreen display and deep integration with the Avinox Ride App.
Smart Offline Navigation
- Import routes from third‑party apps
- Convert historical tracks into GPX/FIT/TCX
- Sync routes with one tap
- Navigate without a phone connection
- Real‑time turn‑by‑turn guidance
- Off‑course alerts
You can finally leave your phone in your pocket and still enjoy full navigation.
Smart Heart Rate Control
Set a target heart‑rate zone, pair a monitor, and the system automatically adjusts motor output to keep you in the optimal zone — ideal for training, pacing or managing fatigue on long rides.
Smart Companion
From ride data to system diagnostics, the PX integrates seamlessly into your daily riding routine, offering convenience and intelligence at every turn.
Lighter, Quieter, More Adjustable Frame
The PX Carbon chassis has been refined for better handling and more tuning options.
What’s new:
- 20 kg total weight (PX Carbon & PX Carbon Pro)
- 41% less motor drag
- <45 dB noise output (down from 48dB)
- 40‑point geometry adjustment
- Adjustable chainstays, linkage flip chips and headset cups
- Mullet setup as standard, with full 29er compatibility
- Slimmer downtube fits the largest possible battery
The PX Carbon rides like a lightweight trail bike — but climbs like a full‑power machine.
Versatile Geometry to Conquer Any Terrain
Amflow has introduced one of the most adjustable geometry systems in the category.
What’s new:
- 5 head‑tube angle positions
- 2 bottom‑bracket height settings
- 4 chainstay length options
- Up to 40 total geometry combinations
This progressive system allows riders to fine‑tune the PX for steep enduro lines, fast flow trails, long climbs or all‑day adventure riding. It’s a bike built for riders who love the art of setup — and the freedom to adapt their ride to any terrain.
The Avinox M2S Motor: A New Benchmark for Full‑Power e‑MTBs
Engineered in Every Detail
- Max Torque: 150 Nm
- Peak Power: 1500 W
- M2S Drive Unit Weight: 2.59 kg
The Avinox M2S Drive Unit delivers a huge leap in performance while remaining incredibly compact. Compared to the previous generation, power density increases by 45.9% and torque density by 21.6%, giving riders more output from a smaller, lighter package.
Surging Power, Naturally Refined
Power delivery is where the M2S truly stands out. Multiple high‑precision sensors and intelligent algorithms constantly adjust output in real time, creating a natural, linear pedalling feel that avoids the abrupt surges common in older systems.
- Auto Mode adapts assistance based on terrain and rider position
- Boost Mode unleashes full power instantly — 150 Nm and 1500 W — for steep climbs or technical bursts
The result is a drive system that feels intuitive, predictable and incredibly capable.
How the M2S compares to other leading motors
• Avinox M2S: 150 Nm / 1500 W
• Avinox M1 (previous gen): 120 Nm / 1300 W
• Specialized S‑Works: 111 Nm / 850 W
• Bosch CX: 100 Nm / 750W
It’s clear: the M2S now sits at the top of the lightweight full‑power e‑MTB class.
Full‑Power Performance Without the Weight Penalty
One of the biggest achievements of the PX Carbon series is how it blends full‑power output with lightweight handling.
At 20 kg, both the PX Carbon and PX Carbon Pro undercut many competitors while still delivering the torque and range expected from a full‑power system.
For context, the Specialized Levo’s motor weighs 4.38 kg — more than a kilogram heavier than the M2S. That difference is immediately noticeable on the trail. The PX Carbon accelerates faster, changes direction more willingly and feels more natural when the power is off, giving riders the best of both worlds: full‑power climbing and lightweight descending.
700 Wh Battery: Custom Cells, Higher Output
- Rated Capacity: 700 Wh
- Charge Cycles: 500
- Battery Weight: 3.18 kg
The PX’s custom‑cell battery platform delivers high output with impressive efficiency. It supports super‑fast charging, allowing riders to top up during breaks and eliminate range anxiety on big days out.
Charge Fast, Ride Free
With 3× super‑fast charging, the PX can be recharged rapidly between rides — ideal for back‑to‑back laps, long weekends or multi‑stage adventures.
Smarter Tech: Navigation, Connectivity and Customisation
The PX Carbon series introduces a completely redesigned display system with a focus on navigation and connectivity. Full mapping and turn‑by‑turn navigation are now built in, with seamless Komoot integration for route uploads. Riders can customise the display layout, colours and data fields, and PX models include a SIM card for connected features such as live tracking and over‑the‑air updates.
