Amflow PX 700Wh Battery Explained: Why 700Wh Can Outperform 800Wh

One of the biggest questions riders ask about the new Amflow PX is simple: why does it use a 700Wh battery when many other bikes use 800Wh?

On paper, a bigger battery sounds better. But with the Amflow PX, the answer is more interesting than just battery size. The PX has been designed around a new high-density battery system that prioritises power delivery, efficiency, weight and performance — not just a bigger number on a spec sheet.

That means the question is not just “How big is the battery?” but also “How well can the battery deliver power?”

Why the Amflow PX Uses a 700Wh Battery

The Amflow PX uses a custom 700Wh integrated battery with an energy density of 220Wh/kg. That is one of the key reasons the bike stays in the 20kg class while still supporting very high motor output and long ride range.

In contrast, the Amflow PR range uses a larger 800Wh removable battery. That gives the PR more raw capacity and removable convenience, but it also adds weight and changes the priorities of the bike.

PR: more battery capacity, removable convenience, excellent range flexibility

What this means on the trail

The Amflow PX doesn’t just have a powerful motor — it is one of the few bikes currently available that can fully sustain that performance. That translates into stronger, more consistent assistance on long climbs and under heavy load, not just short bursts of power.

Why the PX battery unlocks more power

The Avinox system is designed so that the battery directly affects motor performance. To deliver full 1500W output from the M2S motor, it must be paired with the newer high-density 700Wh battery platform.

Many larger-capacity battery systems simply cannot sustain this level of output, which is why they are often limited to lower continuous power — even when using the same motor.

Why Not All 800Wh Batteries Are the Same

One of the biggest misconceptions right now is that a larger battery automatically means better performance. In reality, the type of battery and how it integrates with the motor system matters far more.

Many bikes currently on the market are using older 800Wh internal battery designs paired with newer high-output motors. While this sounds impressive on paper, these systems can actually limit how much power the motor can sustain.

Lower energy density
Less efficient power delivery
Reduced sustained output under load

The Amflow PX, along with a very small number of cutting-edge platforms, uses a new-generation high-density battery system specifically designed to unlock the full potential of the M2S motor.

What Makes the PX Battery Different?

One of the biggest differences is that Avinox has not simply used off-the-shelf battery cells. Instead, the PX battery is built around a new-generation cell design developed to improve packaging, energy density and discharge performance.

This larger-format cell technology allows:

Higher current output for stronger motor performance
Improved thermal management under load
Higher overall energy density

The result is a slimmer, lighter battery that can still deliver extremely high output and fast charging performance.

Battery Capacity Is Not the Whole Story

Riders often compare bikes by battery size alone, but battery capacity is only one part of the picture.

How much power the battery can deliver
How long it can sustain that power
How efficiently it handles heat
How much weight it adds
How quickly it can recharge

So while 800Wh may sound better in isolation, a better-designed 700Wh system can deliver a more impressive real-world ride experience.

PX vs PR: Why the Numbers Look Different

PX Carbon / PX Carbon Pro: M2S motor, up to 1500W peak power available in regular modes with a stronger sustained output
PR Carbon: M2 motor, up to 1100W peak power
PR Carbon Pro: M2S motor, up to 1500W in Boost and 1300W in Turbo.

The PX is the platform built to fully exploit the M2S motor, while the PR range balances performance with removable battery practicality and value.

Fast Charging Matters Too

The PX battery also supports extremely fast charging, helping offset concerns about having “only” 700Wh on paper.

That means riders are not just looking at capacity, but how quickly they can recharge and get back out riding — a major real-world advantage.

What This Means on the Trail

Lighter and more agile handling
Stronger, more consistent power delivery
Better support under sustained load
A more refined overall ride feel

Is 700Wh Enough?

For most riders, yes. And for longer rides, the PX is compatible with a 600Wh range extender depending on frame size.

So you get a lighter, more advanced battery as standard, with the option to extend range when needed.

Why the PX Costs More – And Why It Makes Sense

Lighter, more advanced carbon platform
Next-generation high-density battery system
Designed to fully unlock sustained M2S performance
Stronger performance across all assist modes

The result is a bike that feels noticeably more responsive, more refined and more performance-focused on the trail.

Final Thoughts

The Amflow PX 700Wh battery is not about giving riders less — it is about delivering a smarter, lighter and more advanced system that performs better where it matters.
