New Amflow PX and Amflow PR E-MTBs Bring More Variety – Both Tech-wise and Price-wise

In autumn 2024, Amflow had secured its place in the spotlight with its PL Carbon Pro and PL Carbon models. A few months earlier at Eurobike, the brand had taken the cycling world by storm together with the DJI Avinox. As the only manufacturer with bikes available for delivery, it was able to calmly meet the demand from eager e-MTB enthusiasts. Less than two years later, Avinox is launching the next generation of its electric drive. However, almost 20 competitors – some of them very well-known – now use an Avinox system. The market in which Amflow aims to hold its own with the new Amflow PX and Amflow PR models unveiled today is correspondingly competitive.

2. Amflow PX and Amflow PR remain versatile e-mountain bikes
3. Amflow PX – the successor to the Amflow PL
4. Top-of-the-range model with Avinox M2 S as the crucial piece of the puzzle
5. Amflow PX Carbon Pro and Amflow PX Carbon almost on a par

7. Why choose an Amflow model?

1. New frame offers plenty and demands plenty

Given such changed circumstances, it seems out of the question to simply carry on as before. The question arises: In which direction should the brand develop? With the Amflow PX Carbon and the Amflow PR Carbon, Amflow appears to be targeting a sporty, ambitious and highly advanced riding clientele. At least, that’s what the models’ new frames suggest.

Rarely have we come across an all-trail e-mountain bike that offered so many options for adapting the geometry to different terrains and preferences. You can adjust the frame – which is still made of carbon – in three key areas:

• the head angle
• the chainstay length
• the bottom bracket height

For example, special head tube cups allow you to change the head angle, which is set at 64.2 degrees ex-factory. You can adjust this in five different increments. Each increment allows you to increase or decrease the angle by one degree or half a degree. A smaller, and therefore flatter, head angle would be the best choice if you enjoy extremely steep descents. Conversely, a slightly larger, steeper head angle gives you greater agility on sections with particularly tight bends.

To extend the chainstay length beyond the standard 438 millimetres, there is a suitable flip-chip in the frame. This allows for three further lengths, up to a maximum of 451 millimetres. Longer chainstays give the ebike extra stability at high speeds, which suits a profile that leans towards enduro and downhill. With a shorter chainstay, on the other hand, the Amflow becomes more manoeuvrable.

The flip-chip for adjusting the bottom bracket height is located in the four-link rear suspension with Horst-Link. Here you can choose between two heights – 345 millimetres and 349 millimetres. The four-millimetre increase in clearance between the ground and the bottom bracket ensures that you can clear larger roots, rocks and other obstacles more easily, reducing the risk of getting snagged. In the lower setting, the bike’s lower centre of gravity provides greater grip in corners.

A lot of expertise required

If you factor in the options for adjusting the bottom bracket height as well, there are a total of forty different combinations for the frame geometry. Forty. How many of you are keen to experiment and try them all out? And how many of you are also skilled enough to clearly identify the differences in handling and then select the right one for your own route? This seems to be strongly oriented towards professional cycling. For everyday cyclists, however, this could quickly become overwhelming.

There appear to be certain differences between the frame for the Amflow PX Carbon and that for the Amflow PR Carbon. This is evident, for example, in the weight. The frame for the Amflow PX Carbon weighs around 2.4 kilograms. The one for the Amflow PR Carbon tips the scales at around 500 grams more. One reason for this is likely to be the different approach to the battery. But we’ll come back to that in more detail later. As before, the manufacturer offers its e-mountain bike in four frame sizes. The division into M, L, XL and XXL remains somewhat unusual – at least for the European market.

2. Amflow PX and Amflow PR remain versatile e-mountain bikes

Suspension travel also remains unchanged. The 160 millimetres on the suspension fork and the 150 millimetres on the rear shock fall squarely within the range typically classified as an all-trail or all-mountain bike. Accordingly, both new models should feel equally at home riding both uphill and downhill. Trails featuring small to medium-sized obstacles and jumps are well within their capabilities.

Amflow has now implemented this compromise for varied terrain a little more strongly in the new models. From the factory, these will be delivered with a mullet setup in future. The front wheel measures 29 inches and the rear wheel 27.5 inches. Thanks to the numerous adjustment options on the frame, however, the bikes can also be ridden without any problems with a full 29-inch wheelset. With the old Amflow PL Carbon, it was exactly the other way round.

Another special feature can be found on the handlebars of the Amflow PX Carbon and Amflow PR Carbon. From now on, all models come fitted as standard with Avinox’s in-house front light. This is a rather unusual feature for e-mountain bikes, but one that makes perfect sense, not least with a view to potential night rides. Apart from that, some of you will no doubt also use your e-MTB on public roads. A light can never go amiss there. Especially as selected models also come with a battery-powered tail light.

3. Amflow PX – the successor to the Amflow PL

Amflow is making the most of the capabilities of the second generation of e-drives centred around the new Avinox M2, adding more depth to its range. With two motors and a choice between a permanently integrated and a removable battery, the system manufacturer finally offers a suitable template. Amflow is clearly keen to make use of this.

The Amflow PX model range can be seen as the actual successor to the Amflow PL. With the Amflow PX Carbon Pro and the Amflow PX Carbon, it once again comprises two models. You can easily tell them apart by their frame colours. The top-of-the-range Amflow PL Carbon Pro comes in a shade of grey called Moonstone Gray. Black, or more precisely Phantom Black, on the other hand, indicates the more affordable model this time round, the Amflow PX Carbon. In line with the manufacturer’s previous approach, these are the only colours in which these versions will be available. As things stand.

4. Top-of-the-range model with Avinox M2 S as the crucial piece of the puzzle

Both the Amflow PX Carbon Pro and the Amflow PX Carbon feature the new Avinox M2S. This sportiest version of the Avinox M2 delivers endless power. The standard specifications alone, with a peak power output of 1,300 watts and torque of 130 Newton metres, are impressive. This is topped off by Boost mode, which increases these figures to 1,500 watts and 150 Newton metres.

However, alongside the astonishing motor power, features such as offline navigation using third-party GPS data and the adjustment of assistance to predefined effort zones based on heart rate are likely to significantly enhance the riding experience with the Amflow PX. Using the first feature mentioned, you can import routes from services such as komoot, Strava, Bikemap, Ride with GPS, Naviki and others via the Avinox Ride app. The files must be in GPX, FIT or TCX format. The app also converts your recorded rides into GPS tracks. However, the feature is not yet fully developed at this stage. The display simply shows a track that is not embedded in a map. Therefore, you’ll need to navigate using the route’s path and the actual surroundings. Turn-by-turn directions and a compass on the display make this easier.

Two batteries – but one catch

A degree of scepticism is perhaps warranted when looking at the battery. After all, the new permanently fitted Avinox FP700 intube battery offers a capacity of just 700 watt-hours. This sits exactly between the previously available 800 watt-hours of the Avinox FS800 and 600 watt-hours of the Avinox FS600. According to Amflow, however, Avinox uses different cell types in this battery. As a result, performance on a par with the familiar 800 Wh battery is expected. That would mean you can expect a range of up to 140 kilometres. Under optimal conditions, of course. 😉

Anyone who, given these figures, is still unsure whether this is really enough can opt for a dual-battery solution with the Amflow PX models. Similar to Bosch’s DualBattery option, two batteries can power the ebike system simultaneously. The second battery here is one of the new removable batteries from Avinox – the Avinox RS600. This can be mounted on the down tube. It increases the capacity by 600 watt-hours to a total of 1,300 watt-hours.

However, there is a major limitation here. Only the two frame sizes, XL and XXL, offer sufficient space for the dual-battery variant. It is therefore no surprise that Amflow has announced further configurations. In the medium term, a smaller battery could well follow, which would then also fit frame sizes M and L.

For the time being, most people will probably be using the Avinox FP700 in its standard configuration. Despite its lower capacity, the Amflow PX Carbon Pro weighs slightly more than the Amflow PL Carbon Pro. It is expected to add around one kilogram, so we are ultimately talking about a weight of just over 20 kilograms.

5. Amflow PX Carbon Pro and Amflow PX Carbon almost on a par

Otherwise, Amflow equips the PX Carbon Pro and the PX Carbon in a very similar way. Both feature a Fox suspension system and Sram electronic derailleurs with twelve gears. On the PX Carbon Pro, the components are simply of a slightly higher quality. It is only with its carbon wheelset and carbon handlebars that the top-of-the-range model stands out a little more clearly.

It is pleasing to note just how many accessories Amflow includes with both PX models. In addition to the front light already mentioned, the bike comes with:

• a bottle cage,
• a shock pump,
• a torque wrench,
• a clip-on tail light,
• dropper post travel reducing spacers, and
• frame protection film.

In the case of the Amflow PX Carbon Pro, the list goes even further. You get a free nano-SIM card, which allows you to transmit data for five years, a small mudguard for the suspension fork and a conversion kit for the Schwalbe Clik Valve. Even given the price of 9,999 euros, that’s really impressive to see.

6. Amflow PR – an affordable package featuring the Avinox M2 and a removable battery

In our view, with the Amflow PR, the manufacturer is making a real statement. After all, the 4,499 euros price tag for the Amflow PR Carbon is a real challenge to the competition. The Avinox M2 motor is more powerful, quieter and more robust than the Avinox M1. The bike also features electronic shifting, absolutely reliable suspension components from Fox, and a larger battery than the Amflow PX, which can even be removed.

But first things first. Just as with the PX series, Amflow is also launching two models from the PR range – the Amflow PR Carbon Pro and the Amflow PR Carbon. Both versions are also being launched in just one colour each. Basalt Grey for the Amflow PR Carbon Pro and Moss Green for the Amflow PR Carbon Pro.

When it comes to motor options, the manufacturer takes a two-pronged approach. The entry-level Amflow PR Carbon is fitted with the Avinox M2. The motor’s power output falls slightly short of that of the Avinox M2S. Nevertheless, the 110 Newton-metres and 1,100 watts of peak power in the four standard riding modes – Eco, Trail, Turbo and Auto – are more than what motors such as the Bosch Performance Line CX, Mahle M40, Giant SyncDrive Pro 3 or Qore Drive3 Peak offer. All the more so as the torque peaks at 125 Newton metres in boost mode.

The Amflow PR Carbon Pro once again features the Avinox M2S. We have already mentioned its even greater performance capabilities.

Removable battery as a better solution for everyday use

The most obvious difference between the Amflow PR and Amflow PX is the removable battery on the more affordable model range. Amflow uses the larger of the two variants offered by Avinox – the Avinox RS800. This allows you to charge it separately in the basement, in your home or elsewhere. Thanks to its capacity of 800 watt-hours, it may even offer greater ranges than the Amflow PX’s permanently integrated Avinox FP700.

When it comes to the smart features of the new Avinox drives, the Amflow PR is every bit as good as the Amflow PX. From offline navigation on the display, to locating the ebikes using Apple’s Find My feature, riding based on pre-set heart rate zones, shifting gears with Smoothshift, right through to the customisable screens on the display and in the app – it’s all there.

Amflow keeps the rest of the spec – such as the gear system, brakes, suspension, wheelset, etc. – simpler compared to the PX models. Therfore, the Amflow PR Carbon Pro and the Amflow PR Carbon weigh slightly more. Magazines that have already tested both models report weights ranging from 22.6 kilograms to 24.2 kilograms. The Amflow PR Carbon Pro and Amflow PR Carbon differ from one another primarily in terms of the motor, the suspension components, the brakes and the tyres fitted. Due to its higher-quality specification, the Amflow PR Carbon Pro has a price tag of 5,899 euros. As mentioned, the Amflow PR Carbon starts at 1,400 euros less.

7. Why choose an Amflow model?

Fundamentally, the manufacturer’s models are truly solid e-mountain bikes. You might search in vain for a genuine unique selling point. Instead, the weight, suspension system and gearshift are so well-coordinated that the overall package performs remarkably well on the trails. Everything falls within a range that appeals to many potential buyers.

According to the company itself, Amflow also still enjoys a special relationship with drivetrain manufacturer Avinox. Given their shared history, this is hardly surprising. As soon as Avinox comes up with new innovations, Amflow is likely to be the first to hear about them and implement them. Other competitors have to compensate for this advantage with their own developments.

Furthermore, with the new PX and PR models, Amflow is demonstrating that it is currently developing its own identity and by no means acts as an extension of Avinox’s production line. We see evidence of this, for example, in the new frame or the permanently integrated battery. Amflow has adapted this exclusively for the new PX models. According to our information, other ebike manufacturers will also use a battery of this type with a capacity of 700 watt-hours. However, this is likely to be a standard version offered by Avinox.
