If you’ve been waiting for the Megamo Reason 2027 launch, the big news is now official.
Megamo has updated the Reason range with the new DJI Avinox M2S motor, refined the spec across both the Reason Air and full-fat Reason platforms, and pushed the bike a little further towards proper modern trail and enduro use.
That matters because this is not just a minor motor swap. The new range brings more power, tougher build choices, a clearer split between 140 mm Air models and 160 mm Reason models, and more buying options across carbon and alloy.
If you’re wondering what has actually changed, which model makes the most sense, and whether the new range is worth your money, this guide breaks it all down. If you also want broader background on how the platform rides, our Megamo Reason review is worth a read too.
🔑 Key Takeaways
The headline update is the Avinox M2S motor: up to 150 Nm in Boost mode with 1300 W peak power.
The range now feels more clearly split: Reason Air for lighter 140 mm trail riding, Reason for bigger 160 mm enduro use.
Spec has moved in a tougher direction: Fox 38 forks on key 160 mm builds, stronger tyre choices, and more aggressive model identities.
There is now a build for most budgets: alloy models start at £4,999, with carbon builds stretching up to £11,999.
For most UK riders, the real choice is not “best bike”: it is whether you want Air vs Reason, then alloy vs carbon.

What’s New on the Megamo Reason 2027 Range?
The biggest update is easy to spot: the Megamo Reason 2027 range now uses the new DJI Avinox M2S system rather than the previous generation setup.
On paper, that means:
Up to 150 Nm torque in Boost mode
1300 W peak power
800 Wh integrated battery across the range
2-inch Avinox DP100 OLED touchscreen display
That alone would be enough to make the launch interesting, but Megamo has not stopped there.
The more important story is that the 2027 Reason range has been tightened up as a complete family. The Air bikes remain the lighter, faster-feeling 140 mm option, while the standard Reason models lean harder into 160 mm all-mountain and enduro riding.
There are also several spec changes that push the bikes in a more capable direction:
Fox 38 forks on key 160 mm builds instead of lighter-duty front-end options
Tougher tyre choices on the bigger-hit models
Multiple AXS build options for riders wanting wireless shifting
An XL size added for taller riders
A broad price spread from more accessible alloy builds to flagship carbon bikes
If you liked the original Reason but thought some builds looked slightly under-gunned for aggressive riding, the new range makes more sense straight out of the box.
The Megamo Reason 2027 keeps the slim integrated look that made the original bike stand out, but the latest range brings more power and a more sorted model lineup.

Megamo Reason Air vs Megamo Reason: What’s the Difference?
This is the first real buying decision most riders need to make.
The Reason Air and the standard Reason share the same family look, the same Avinox M2S system, and the same premium slim-integration feel. The difference is in travel, attitude, and the type of riding each bike is built around.
Reason Air
140 mm travel front and rear
Available in alloy and carbon
Lighter, quicker-feeling, more trail-focused
Best suited to riders who value agility, long rides and a more lively feel
Reason
160 mm travel front and rear
Available in alloy and carbon
More enduro-biased, more planted, burlier spec on key models
Best suited to riders hitting rougher descents, steeper terrain and more demanding trails
For plenty of UK riders, that means the choice is actually simpler than it first looks.
If most of your riding is:
trail centres
big natural loops
fast singletrack
long rides where efficiency still matters
then the Reason Air 2027 range will likely make more sense.
If your riding is more about:
steeper descents
rougher natural terrain
bigger hits
more aggressive all-mountain or enduro use
then the standard Megamo Reason 2027 models are where you should be looking.

Megamo Reason 2027 Carbon vs Alloy: Which Makes More Sense?
Once you’ve chosen Air vs Reason, the next question is whether you want alloy or carbon.
The good news is that this does not feel like a “good frame / bad frame” decision. Both materials give you access to the same core 2027 platform, the same Avinox M2S system, and the same broad model identity.
The real difference is in budget, refinement, and how far up the spec ladder you want to go.
Why choose alloy?
Better value entry point into the 2027 range
Same motor and battery experience as higher-end builds
Ideal for riders prioritising performance per pound
Strong option if you would rather spend less now and upgrade touchpoints later
Why choose carbon?
Lighter, more premium overall package
Higher-end builds and finishing kit
Better fit if you want top-spec suspension, wheels or AXS options
Appeals to riders chasing maximum refinement rather than just value
For most riders, the most honest advice is this:
If budget matters, go alloy without feeling like you are settling.
If you want the sharpest, most premium version of the bike, go carbon.
That is especially true in a range like this, where the motor and battery story stays strong all the way through.
Which Megamo Reason 2027 Model Suits You?
This is where the range gets more useful.
There are a lot of models, but most buyers are really only asking one question: which build makes the most sense for how I actually ride?
If you want the most accessible way into the range
Look at:
Reason Air AL 07 (2027)
Reason AL 07 (2027)
These are the gateway models for riders who want the 2027 platform and Avinox M2S performance without jumping straight to carbon money.
Choose the Air AL 07 if you want the lighter, 140 mm trail flavour.
Choose the AL 07 if you want full 160 mm travel and a more enduro-ready bike.
If you want the sweet-spot value build
Look at:
Reason Air AL 05 (2027)
Reason AL 05 (2027)
Reason CRB 05 (2027)
This is where a lot of smart buyers will end up.
The AL 05 models tend to give you a stronger balance of suspension and drivetrain without wandering too far into top-end territory, while the CRB 05 gives you a genuine carbon step-up without having to chase the absolute flagship.
If you want wireless shifting
Look at:
Reason Air CRB 03 AXS (2027)
Reason AL 03 AXS (2027)
Reason CRB 03 AXS (2027)
If you specifically want the cleaner feel and convenience of SRAM AXS, these are the builds to focus on. The smart choice then becomes deciding whether you want Air vs Reason and alloy vs carbon, rather than getting distracted by every model name in the range.
If you want the premium halo build
Look at:
Reason Air CRB 00 (2027)
Reason CRB 01 (2027)
These are the bikes for riders who want the top-tier carbon version of each platform.
The Reason Air CRB 00 is the premium 140 mm choice.
The Reason CRB 01 is the full 160 mm flagship.

Is the New Megamo Reason 2027 Range Worth It?
For the right rider, yes - absolutely.
The reason this launch matters is that the Megamo Reason 2027 does not just add a bigger headline number and call it progress. The range looks more coherent now.
The Reason Air models feel easier to understand as the fast, lively 140 mm option.
The standard Reason models now make even more sense as the tougher 160 mm bikes for bigger terrain.
That clarity matters when you are spending this sort of money.
The Avinox M2S update also gives the range a stronger identity in a crowded e-MTB market. If you already liked the slim frame design, big battery capacity and modern feel of the original Reason, the 2027 launch gives you more reasons to take it seriously rather than less.
If you are choosing with your head rather than just launch hype, the smart route is:
Choose Air vs Reason first
Choose alloy vs carbon second
Then shortlist the best-value build within that lane
That is usually a better buying method than simply chasing the most expensive model.

FAQs – Megamo Reason 2027
What is new on the Megamo Reason 2027?
The main update is the move to the DJI Avinox M2S motor, along with a stronger and more purposeful model lineup. That includes tougher spec choices on key 160 mm builds, clearer separation between Reason Air and Reason, and new options such as an XL frame size.
What is the difference between Megamo Reason Air and Megamo Reason?
Reason Air models use 140 mm travel and are aimed more at trail riders who want a lighter, quicker-feeling bike. Standard Reason models use 160 mm travel and are aimed more at aggressive trail, all-mountain and enduro-style riding.
Is the Megamo Reason 2027 available in carbon and alloy?
Yes. Both the Reason Air and standard Reason platforms are available in alloy (AL) and carbon (CRB) versions, so you can choose based on budget and spec preference.
Which Megamo Reason 2027 model is best value?
For many riders, the value sweet spots will sit around the AL 05 and CRB 05 level, depending on whether you want alloy or carbon. The best-value model for you will still depend on whether you want the lighter Air platform or the bigger 160 mm Reason platform.
Is the Megamo Reason 2027 worth buying?
If you want a modern full-power e-MTB with a big battery, very strong motor figures, and a range that now makes more sense from top to bottom, the Megamo Reason 2027 is definitely worth shortlisting. The real trick is choosing the right version rather than assuming the flagship is automatically the best buy.
