Mondraker Zendit RR S vs Amflow PX — which for Alps?

[pbush68]

Hey, morning, i’m buying a new bike and can’t decide between Mondraker Zendit RR S or the Amflow PX, i live in alpes and currently have a 2021 Santa Cruz Heckler CC and a normal YT Capra, i want the new bike to replace both. Any opinions?

Morning. Replacing both a Heckler and a Capra in one bike is a tall order, but both of these are actually reasonable candidates for it.

The Zendit RR S runs the Avinox M1 (the original, not the new M2/M2S), which is a strong motor but worth knowing you're not getting the latest hardware. It's a proper enduro chassis, geometry aimed squarely at rowdy terrain, which suits the Alps well. You'd be losing nothing from the Capra in that regard.

The Amflow PX is a different proposition. It runs the Avinox M2S, which is currently the most powerful production eMTB motor going — 130Nm, 1,300W continuous, and independent testing has it hitting over 1,400W peak. For Alpine climbing that's not just a number, that's actually meaningful. It also comes with the new FP700 integrated 700Wh battery. It's a newer bike from a brand that doesn't have the pedigree of Mondraker yet, which is a fair concern.

The honest answer: if you're replacing a Heckler AND a Capra, the PX is probably the more interesting tool. The motor advantage is real, and Alpine riding rewards it. The Zendit is the safer brand choice but you'd be buying into last year's Avinox spec at new bike prices.

What size are you riding on the Capra? Worth checking where you'd land on both bikes before going further.

The new Zendit does run the M2S?

Very different bikes, the amflow does have adjustable geo which could band aid it to fit more situations, the zendit really is built to shred

Good news - I got that wrong in my first reply. The 2026 Zendit does indeed run the M2S, not the M1. Our database has it confirmed: Avinox M2S, 150Nm continuous, 800Wh battery. So both bikes are actually on the same motor generation, which changes the comparison considerably.

@pbush68 - and @zerofunds makes a fair point above. The Zendit is very much built to shred: 170/165mm travel, full carbon, mullet setup, geometry that wants to go fast downhill and doesn't particularly apologise for it. The PX Carbon is shorter travel (160/150mm) but has that adjustable geometry chip, which gives it more range of character. For someone replacing both a Heckler and a Capra, that flexibility probably matters.

The other practical difference: the PX runs the FP700 integrated 700Wh battery. The Zendit has an 800Wh pack. In the Alps, where you're covering serious elevation, 100Wh is not nothing - especially since @Rando_12345 flagged that the FP700's cells aren't particularly impressive and there's no range extender option currently. The Zendit edges it on raw battery capacity.

Motor is now a draw. Battery goes to Zendit. Geometry flexibility goes to PX. What's your height? Worth checking where you land on sizing for both before going further, as the Zendit's geometry is quite committed.

@zerofunds is largely right, but the Zendit picture is a bit more nuanced than "no adjustability." The Zendit does have a 2-position flip chip at the lower shock mount, but

it's fairly surgical - a 0.35° head angle tweak and 5mm BB height change. That's fine-tuning, not a personality swap. Compare that to the PX's geometry chip which meaningfully shifts the bike's character between more trail-friendly and more slack/aggressive positions. The Zendit's chip is really "this or slightly more of this."

The Zendit does also let you run a full 29" rear wheel via a separate lower link flip-chip, which is a genuinely useful range extender for Alpine touring days where you want roll-over efficiency on the climbs. That's a practical advantage.

But fundamentally, the Zendit is built for speed - it quickly builds a high base speed and feels most at home right there, planted and high-traction in rough terrain. It's not a playful corner carver; changing direction requires deliberate input. That's the Capra replacement part of @pbush68's brief covered, but the Heckler's more versatile, can-do-anything character? That's where the PX's adjustable geo genuinely does give it more range.

Both have chips. One has options, the other has a fine-tune. Worth keeping that distinction clear.

Thanks for the reply, much appreciated, when i said i want the bike to replace both, i thought i was talking to my wife (lol) i may well keep the capra! Zendit looks a lot more aggressive to me and i think i will need to downsize to a small, on a medium for the Capra and Santa Cruz, but the Zendit is longer. Im 171cm, again any opinions? thanks all

Good news, you've just made the decision a lot easier. Keeping the Capra and letting the new bike be a proper Alpine weapon means you can lean fully into the aggressive end of the spectrum, which plays directly to the Zendit's strengths.

On sizing at 171cm: you're in a genuinely awkward spot between Small and Medium on the Zendit. I'd want to web search the exact 2026 Zendit geometry table before committing to a number, as I don't have it verified in front of me. What I can tell you is the Mondraker DNA tends to run long - their Forward Geometry philosophy pushes reach numbers beyond what most brands do at equivalent sizes. So where you'd naturally sit on a Medium Capra (465mm reach, for reference), a Medium Zendit could well feel a size up rather than equivalent.

The other factor: the Zendit is built for speed and wants deliberate input to change direction. On a bike like that, sizing down tends to work in your favour in tight Alpine switchbacks and technical terrain, where a too-long front centre fights you. Sizing up rewards you on open, fast descents where stability is king. Both are valid Alpine use cases, so it really comes down to which trails you ride most.

Strong suggestion: get on both sizes before buying if there's any way to do it. Mondraker dealer demo or Zendit owners in your area - sizing on this bike specifically is not one to guess at. Want me to pull the full 2026 Zendit geometry table for S and M so you've got the actual numbers to work with?

Cheers, the Zendit reach small is 440, same as Capra the medium is 460, so like you say im in the middle. The Capra is 5 years old now and is light and easy to throw around, maybe i should get out of my comfort zone and go a bit longer? most of my riding is not park (to old) its tech mountain trails switchbacks, drops, not man made.

Good instinct to question it. At 171cm with your Capra experience on a Medium (465mm reach), you're sat in exactly the zone where both Zendit sizes are defensible, and your reasoning is sound.

The argument for going up to Medium (460mm reach): your current Medium Capra is 465mm, so a Zendit M at 460mm is actually marginally shorter in reach than what you're already riding. You wouldn't be stretching into unknown territory, you'd be sitting in familiar numbers on a bike built to go faster. For tech mountain trails with drops and committed terrain, that extra 20mm of wheelbase over the Small gives you composure when things get rowdy. Mondraker's Forward Geometry generally pairs longer reach with short-ish stems, so the cockpit doesn't feel as stretched as the reach number suggests.

The argument for Small (440mm): tight natural switchbacks. Non-manicured alpine tech with awkward pivot turns is where a shorter front centre genuinely helps. If your local trails are more "thread the needle between trees" than "open fast rock chutes," the Small will reward you.

My read: given you've been happy on the Medium Capra for five years and your riding is tech but not park, I'd lean Medium Zendit. You're used to 465mm. 460mm on a more planted, faster-feeling chassis is a natural progression, not a leap. Going down to 440mm after half a decade on 465mm is the bigger adjustment, and not necessarily in a good way.

pretty sur ethe capra medium 2020 is 440 reach?

 

[Greg Watts]

pretty sur ethe capra medium 2020 is 440 reach?

You're right to push back, and I owe you an apology for confusing myself earlier.

The 2020 YT Capra 29 in Medium has a 440mm reach, not 465mm. Size Large is where 460mm lives. I was inadvertently quoting the newer Capra geometry at you.

That actually changes the recommendation quite a bit. If you've been happy on a 440mm reach Medium for five years, then the Zendit Small at 440mm is a direct like-for-like and the Medium Zendit at 460mm is a genuine step up, not a familiar position.

Given your riding profile, natural tech with switchbacks, drops, non-manicured terrain, I'd now lean the other way: Small Zendit makes more sense. You already know 440mm works for you in tight, technical Alpine terrain. The Medium would be a 20mm reach increase on a bike that's already more committed and faster-feeling than your Capra. That's two variables changing at once, which is how people end up with bikes that feel like work rather than fun.

The "get out of your comfort zone" argument is valid, but for natural tech rather than bike park, agility tends to beat stability. The Zendit will already feel more planted than the Capra at any size, just from the motor weight and updated geometry. You don't need to add length on top of that to get the benefit.

Small Zendit would be my call. Apologies again for the earlier number mix-up.

EDIT: @Mistery reports The 2020 YT Capra 29 in Medium has a 440mm reach (not 465mm). Size Large is where 460mm lives. Not yet independently verified — take with a pinch of salt.

Zendit has m2s motor.

Appreciated, @Mistery - and yes, I already corrected that earlier in the thread when @pbush68 flagged it. The 2026 Zendit does run the M2S. Verified in our database.
