Amflow PX vs PR: Which E-MTB Is Worth Your Money?
Cyclo Monster’s Amflow PR and PX comparison: UK retail prices, claimed bike weights and what each upgrade buys.
Amflow PX vs PR: which electric mountain bike should you choose? The names look similar, but there are useful differences in price, weight, battery design and equipment. Getting the right bike starts with deciding which of those differences will improve your own riding.
The range runs from the £3,999 PR Carbon to the £8,999 PX Carbon Pro. However, the most interesting comparison for many buyers is the £5,399 PR Carbon Pro against the £6,499 PX Carbon. They share several major components, yet the PX is significantly lighter and the PR has a larger, removable battery.
At Cyclo Monster in Spondon, Derby, our buying advice is straightforward: choose the features you will actually use. This guide explains all four bikes and the reasons you might spend more. It is a specification-based comparison using Amflow’s published information, rather than a claim that we have ridden every model back to back.
Amflow PX vs PR: prices and weights at a glance
| Model | UK retail price | Claimed weight* | Battery | Motor torque: nominal / peak |
|---|---|---|---|---|
| PR Carbon | £3,999 | 22.6kg | 800Wh, removable | Avinox M2: 110 / 125Nm |
| PR Carbon Pro | £5,399 | 23.1kg | 800Wh, removable | Avinox M2S: 130 / 150Nm |
| PX Carbon | £6,499 | 21.0kg | 700Wh, integrated | Avinox M2S: 130 / 150Nm |
| PX Carbon Pro | £8,999 | 20.6kg | 700Wh, integrated | Avinox M2S: 130 / 150Nm |
Amflow’s claimed size M weights, with tubeless wheels and without pedals, lights, mudguards or frame protection film. Actual weights vary. Peak torque refers to Boost mode. Prices and specifications checked 16 September 2026 and subject to change.
These figures show why price alone does not tell the whole story. The PR Carbon Pro is heavier than the standard PR Carbon, despite costing more. Its upgrade is about its motor and equipment package. The PX models put greater emphasis on low overall weight.
Weight information comes from Amflow’s PR FAQs and PX FAQs. Compare the same frame size and setup when looking at figures from different sources.
PR Carbon: the lowest-priced way into the range
At £3,999, the PR Carbon makes sense for riders who want an Amflow e-MTB while keeping their spending under control. Its removable 800Wh battery is a practical attraction, particularly if the bike lives somewhere without a convenient charging socket.
The equipment includes a FOX AWL HD Sport fork, Float Rhythm rear shock, SRAM S1000 electronic Transmission gearing and Tektro TKD173 brakes. Its M2 motor has lower published torque than the M2S fitted to the other three bikes.
Our view: start here if price is your main consideration. Work out whether your riding calls for the Pro’s upgrades before stretching your budget. A more expensive model is only better value for you when its extra features solve a real need.
PR Carbon Pro: what does another £1,400 buy?
The £5,399 PR Carbon Pro is a substantial equipment step. It gains the M2S motor, FOX 36 Performance fork, Float X Performance rear shock, Magura Gustav Pro brakes and a 508W fast charger. The standard PR comes with a 168W charger. Both retain an 800Wh removable battery and SRAM S1000 gearing.
For a customer, that means the upgrade reaches several parts of the riding experience: assistance on demanding climbs, suspension performance on rough ground, braking equipment and charging convenience. It is a broader package than a change in appearance or a small weight saving.
We see the PR Carbon Pro as a strong starting point for regular trail riders who want upgraded equipment and easy battery access. The component differences are listed on Amflow’s PR specification page.
PX Carbon: is it worth £1,100 more than the PR Pro?
This is the decision that deserves the closest look. The PX Carbon costs £6,499, but its headline suspension, brakes and gearing are the same component models as those on the PR Carbon Pro. It also uses the M2S motor. Paying the extra £1,100 therefore needs a more specific reason.
The key benefit is the complete-bike weight: 21.0kg against 23.1kg in size M. That is approximately 2.1kg, or 9%, less bike to move around. Comparing frame weights alone understates the difference between the complete bikes.
We would expect that reduction to be useful when lifting the bike, negotiating awkward obstacles or making repeated changes of direction. Riders who enjoy actively moving the bike underneath them may place considerable value on it. These are practical expectations from the weight difference, rather than a substitute for comparing the bikes yourself.
The trade-off is the PX’s integrated 700Wh battery. You give up 100Wh of capacity and the PR’s straightforward battery removal. If you prioritise long outings or need to carry the battery indoors to charge, the PR Pro may suit your routine better.
Our recommendation: choose the PX Carbon when lower weight is a clear priority and you can comfortably charge the bike where it is stored. Choose the PR Carbon Pro when you want a similar major-component package with more battery capacity for less money.
PX Carbon Pro: what does the top model add?
The PX Carbon Pro costs £8,999, a £2,500 increase over the PX Carbon. Its main upgrades include FOX Factory suspension with a GRIP X2 fork damper, SRAM X0 Transmission, carbon wheels and a carbon handlebar. The M2S motor, 700Wh battery and Magura Gustav Pro brakes remain.
The suspension offers more adjustment, giving riders greater scope to tune its behaviour. That is most appealing if you understand the adjustments, enjoy experimenting with setup or want help developing a setup for your preferred terrain.
Its claimed size M weight is 20.6kg, saving around 0.4kg over the PX Carbon. The spending decision is therefore mainly about the premium equipment package. If you would otherwise plan several major upgrades, buying the specification you want from the start is worth considering.

Removable 800Wh or integrated 700Wh: which suits you?
Battery design affects ownership every week. With a PR, you can remove the battery for charging while leaving the bike in its storage space. That can make life easier in a garage, shared storage area or another location where bringing the whole bike to a socket is inconvenient.
The PX battery is integrated. Amflow states that removing or replacing it requires the drive unit to be removed, so it is a workshop operation rather than a routine charging step. Think about where the bike will live before deciding that the lighter option is automatically the better one.
An 800Wh battery stores about 14% more energy than a 700Wh battery. That does not guarantee 14% more distance: rider weight, climbing, assistance settings, tyres, temperature and the bike itself all affect consumption. Your usual ride length and preferred assistance level are more useful starting points than an optimistic headline range.
If you finish most rides with plenty of battery remaining, the PX’s lower capacity might be an easy compromise. If you regularly use most of your battery, extra capacity may have more value than saving weight.
Fit and setup still come first
All four models are offered in M, L, XL and XXL. However, the PR and PX have different geometry, so the same size label does not promise exactly the same riding position.
Use Amflow’s PR sizing guidance and PX sizing guidance as starting points, then check how the bike fits you.
For riders in Derby, Spondon, Borrowash, Ockbrook, Chaddesden and the surrounding area, a visit to Cyclo Monster is an opportunity to discuss your height, riding style and the terrain you enjoy. Ask us which models and sizes are available to view before travelling.
