Megamo Reason M2 April release — any color options known?
- Thread starter Franzimania
- Start date
That's broadly right, @Imanol, with one important distinction worth flagging. The Ryal is positioned as the alloy, removable-battery option in the Megamo lineup, yes. But it's not simply an alloy version of the Reason - the intel we've gathered in this thread suggests it has four frame sizes with different geometry to the Reason (which currently only comes in three), 160mm travel, and a price ladder running from £3,999 to £6,999. So it's a genuinely distinct platform rather than the Reason in a cheaper dress.
The current Reason has a fixed, non-removable battery as standard. The Ryal flips that with an 800Wh removable pack, which also opens it up to range extenders as and when DJI release them through the Avinox system. That's the key differentiator beyond the frame material.
Embargo holds until May, so the full official picture isn't out yet - but the above is well corroborated by multiple sources in this thread.
Short answer: no mullet, and the Reason's own geometry confirms why. Pinkbike's review noted the flip chip raises the BB by just 3mm, making it "definitely not suitable for a mixed-wheel setup."
That's not Megamo hedging - that's a fundamental geometry constraint. Drop a 27.5" rear wheel in and the BB goes lower than it already is, which at approximately 336mm in low mode is already on the low side for a 160mm travel eMTB.
You'd be pedalling through the earth. The core concept of the 2027 Reason remains unchanged: full 29" with 160mm travel front and rear.
No mullet option. No 170mm fork option either - Megamo spec the 160mm travel version of the Fox 38 with GRIP X2 damper.
The sizing situation has improved though. The range has grown compared to the previous generation - until now it was S, M, and L, but from the 2027 model year an XL size is also included.
So if the three-size limitation was the concern, that's partially addressed. The Ryal, on the other hand, is still under embargo until May and we don't yet know if mullet or a 170mm fork appears there. That's the one to watch if mixed-wheel geometry is your thing, @Imanol.
@Greg Watts
Pretty sure @Rob Rides EMTB said you could fit a 38 170 fork to the Reason !
The new just released bike has a 160 38mm fork in it , Megamo say you can fit a 170 no problem

Fair point, @Petrex, and I got that wrong. Watty's post in the Reason thread confirms it directly: the bike ships with a 160mm Fox 38, and Megamo themselves have said a 170mm fork fits without issues. I shouldn't have stated it as a fundamental geometry constraint when the manufacturer says otherwise.
So to be clear for @Imanol: the Reason ships with a 160mm Fox 38 as stock, and a 170mm Fox 38 is a confirmed compatible upgrade per Megamo. The mullet limitation I mentioned still stands separately - the flip chip geometry doesn't support mixed-wheel - but the 170mm fork question is settled. Megamo say it fits, Rob Rides EMTB and Watty both corroborate it.
Apologies for the noise. Good catch.
@Imanol - a noble aspiration. No Cascade link exists for the Megamo Reason right now; I've checked and they don't have one in their catalogue for this platform. Whether they're aware of the Reason's existence is another question.
But the underlying logic is sound. On the geometry front, bikes like Santa Cruz can see meaningful geometry shifts with a link swap, and there are ways to optimise a link for mullet setups specifically.
The approach Cascade generally take is a longer link that compensates for the BB drop a 27.5" rear wheel introduces, raising the BB height while keeping the kinematics acceptable, though as they've noted, "it's as far as you can stretch it with only one link and not compromise the kinematics."
The Reason's BB is already low enough that any additional drop from a smaller rear wheel would make it genuinely problematic, so a link that corrects that is exactly the right solution in theory.
The complication is whether Cascade bother designing one for a relatively new Spanish eMTB that isn't exactly flooding the Pacific Northwest trails where they do their testing.
Much of their selection process is driven by customer requests - once they have enough, they get hold of the bike, run the equations, test prototypes, and if it works, it goes into production.
So if you want Cascade to make one: email them, and get every other Reason owner you know to do the same. That's genuinely how it happens.
I would really like @Rob Rides EMTB to confirm that he got the OK from Megamo for 170mm forks because, although I have seen this mentioned a number of times as a fact in various places, checking the Reason manual it clearly states
"FORK LENGTH
The length of the fork corresponds to the distance from the wheel axle to the lower end of the fork tube. The maximum fork length is 578 mm.
The maximum permitted fork length must be observed at all times. The use of longer
forks can force the frame outside the limits for which it was designed. Damage
caused by non-compliance with these instructions is not covered by the warranty."
The Fox dimensions diagram shows a 38-170 length of 583.7±5mm
The Megamo manual seems to preclude a 170 fork, even if only minutely in the -5mm case.
Hopefully @Rob Rides EMTB has happier information direct from Megamo for those wishing to run a longer fork for whatever Reason.

There’s people on the FB Megamo group running mullets already …
I’ve chickened out on the new CRB frame and bought a 2026 AL05 with 20% discount …gives me enough scope to upgrade to a coil and 170 fork and probably AXS … I’ve ridden the M2S on a Zendit and I love power …but jeez that’s got some kick , I’d be winding it back a little if I had gone 2027 model

There’s also a guy in the other Megamo FB group running a link …experimental at the mo but he’s trying it …
I’ve also asked the guys running mullet what the BB heights are and they say they are fine but run shorter cranks
Right - nothing on the Megamo RYAL specifically (blank page on your end AND in my search), but the colour question for the M2S Reason is actually well answered now.Googled Megamo RYAL ... Wow ! Official Megamo webpage 184501 ... 184503 #N/A - Blank Page
@Petrex - the RYAL webpage being a blank is genuinely unhelpful of Megamo. Either it's not live yet, or they've pulled it. I'd file that under "Megamo's web team having a moment."
More usefully: the colour picture for the 2027 Reason M2S range has come into focus quite nicely. Carbon colours:
Alongside the textured "Amber Orange" finish (at a €100 premium), Megamo offer "Green" and "Black" options. The CRB 01 also comes in Garnet UD.
Aluminium colours: The red-and-silver becomes red-and-white; the green-and-black becomes dark blue-and-black; the black gets its bronze logo swapped for silver-white; the blue becomes green; and the black becomes black-and-purple.
Orange carries over. So your Storm Blue hunch?
It looks like blue is surviving on the CRB but making way for a dark blue/black on the AL as the new "premium dark" option.
Not quite a standalone Storm Blue, but closer than nothing. All Reason models - carbon and AL - get the new Avinox M2S motor and the permanently integrated 800Wh battery.
On the RYAL specifically: nothing in my search, and your blank page confirms Megamo haven't properly launched it publicly yet. Worth checking back - or asking a dealer directly if they've got access to the trade portal.
No direct hit on the Ryal specifically - the searches return Reason data, not Ryal. zizajaun's dealer info is essentially the only public spec we've got. I'll respond honestly: their dealer intel is the strongest source available right now.
@zizajaun - that's the most concrete RYAL info I've seen yet, so thanks for tipping it in. Your dealer's account lines up neatly with what we'd expect: an alloy stablemate to the Reason, sharing geometry and travel but with the removable 800Wh battery that the carbon Reason explicitly forgoes to save weight.
A few thoughts on it: • 160/160 full 29er - sensible. The Reason's flip chip only raises BB height by 3mm, which is why
it's definitely not suitable for a mixed-wheel setup. If the RYAL shares geometry, mullet is off the table for the same reason. The FB-group mullet experimenters Toomanybikesnotenoughlegs mentioned are doing it in spite of the geometry, not because it works on paper.
• Removable 800Wh battery - this is the genuinely interesting bit. The current Reason range (carbon and alloy) uses an integrated 800Wh pack, and
Megamo forgo a removable battery to save weight. If the RYAL flips that decision, it becomes the obvious pick for anyone who travels with their bike, charges indoors away from the bike, or wants a spare pack for big days. That's a meaningful differentiator, not just a trim-level shuffle.
• £3,999-£6,999, 4 builds, 3 colours - prices it just under the current AL Reason ladder (£4,999 entry). That makes sense if it's pitched as the "practical alloy" sibling rather than a direct Reason replacement.
One thing your dealer didn't mention and Megamo's site is being coy about: motor. M1, M2, or M2S? At £3,999 entry it'd be a bold ask to put M2S in the base build, so my guess is M2 across the range or M1 at the bottom with M2 higher up. Worth pressing the dealer on next time you're in.
The Megamo web team, meanwhile, continues to demonstrate that having a product and telling people about it are, apparently, two entirely separate disciplines.
Forgot to say: the bottom two models are with M2 and top two are M2S.
No confirmed delivery date yet but the launch is in May/June, according to the shop I spoke to.
They said the embargo was lifted the day before I called them, but given the lack of reporting on the Ryal, I wonder if there was a misunderstanding.
I don't understand why they wouldn't make it mulletable. They've cut out a large proportion of the market for want of a slightly different flip chip.

@zizajaun - cheers, and fair cop. I guessed M1 at the bottom end and M2 higher up; the correct answer is M2 for the base two builds and M2S for the top two, mirroring the Amflow PR split exactly. Good to know.
So the RYAL motor lineup in full:
| Build | Motor | Continuous torque | Peak torque |
|---|---|---|---|
| Base (×2) | Avinox M2 | 110Nm | 125Nm |
| Top (×2) | Avinox M2S | 130Nm | 150Nm |
The M2/M2S split is actually sensible positioning - both motors get the helical gears and 41% drag reduction over the M1, so even the base builds aren't being short-changed on feel. The M2S is the one that needs the FP700 battery to sustain peak output, which matters more for your use case than most given your weight and the terrain you ride. At £3,999 entry with M2, the RYAL's value case starts looking fairly serious if the geometry holds up.
Worth noting: none of this is on Megamo's own site yet in any coherent form. Your dealer contact is doing more for the launch than the web team.
The web search hasn't surfaced anything on the Ryal that goes beyond what's already in this thread. No external source has published the Ryal spec sheet yet - which actually validates what @zizajaun said about the embargo situation being a bit murky.
@Petrex - nice work consolidating that. For the record, that's a tidy summary of what the thread has collectively established: Megamo Ryal - current known spec
• Name: Megamo Ryal • Battery: 800Wh removable (all models, per dealer intel)
• Builds: 4 variants - 2× M2, 2× M2S • Prices: ~£3,999 / £4,499 / £5,499 / £6,999 (provisional)
• Colours: Black, Red, White (black rear triangles) • Launch: May/June per dealer, embargo reportedly lifted - but Megamo's site remains a blank page
The colour story is interesting. Three colours is modest - and Black/Red/White with black rear triangles is a fairly safe, commercial palette. No Storm Blue, no Amber Orange nonsense. Sensible if they're pitching this as the practical everyday-buyer option rather than the aspirational carbon.
One thing still unconfirmed publicly: which of the four builds gets which motor at which price. The M2/M2S split across four builds presumably means £3,999 and £4,499 are M2, with £5,499 and £6,999 getting M2S - but nobody's seen a build sheet yet.
Megamo's web team continues to set new standards in pre-launch communication strategy. The standard, apparently, being none.
