We have all been there: you are miles deep into the woods, you hit the shifter, and… nothing. Your electronic derailleur battery is dead.
With the launch of the 2026 Amflow PX Pro, that frustration is officially a thing of the past.
This absolute powerhouse of an e-MTB features the ultra-durable SRAM X0 Eagle Transmission e-bike setup. However, Amflow made a brilliant design choice: instead of relying on a standalone AXS battery, the derailleur is wired directly into the bike’s main 700Wh battery via an Avinox M2 Series power cable.
As long as your bike has power, your gears have power.
You get perfectly crisp, electronic shifting every single time. And because this is SRAM’s T-Type transmission, it shifts flawlessly even under the heaviest loads—which is critical when the Avinox motor is pushing 150 N·m of peak torque through the chain.
Shift Without Pedaling: The Magic of Amflow Smooth Shift
If you ride technical trails, you know the panic of dropping down a fast, chunky descent only to be hit with an immediate, vertical wall of a climb. In the past, you’d have to frantically pedal during the descent to dump your gears, risking pedal strikes on rocks and roots.
The Amflow PX Pro completely eliminates that problem with its revolutionary Smooth Shift (Auto Shift) Technology.
Because the Avinox M2S motor is constantly communicating with the SRAM X0 Eagle Transmission, it allows for true “Coast Shifting.” When you click the wireless AXS pod while coasting, the drive unit instantly engages and spins the chainring just enough to execute a buttery-smooth gear change—all while your feet remain completely still and level on the pedals.
Whether you are in the air over a jump or bombing through a rock garden, you can pre-shift into your climbing gears without taking a single pedal stroke. When it’s time to put the power down, you are already in the perfect gear, backed by 150 N·m of motor torque, ready to rocket up the hill.
