Bikes with Avinox M2 motor under 46 lbs?

[sanjosedre]

Hey everyone, what bike using the avinox m2 motor weighs under 46 lbs

@Greg

 

[Greg Watts]

Good question, and a fairly narrow one given the M2 only landed in April 2026.

The Amflow PR Carbon is the confirmed M2 bike. My database has it, and it's built around keeping weight competitive. Whether it scrapes under 46lbs (roughly 20.9kg) depends on the build level — the base PR Carbon uses the M2, while the PR Carbon Pro steps up to the M2S.

I don't have a confirmed published weight for the PR Carbon in my verified data right now, so let me be straight with you rather than invent a number. The M2S bikes (Amflow PX etc.) are the flagship builds and weight figures are starting to filter through, but the PR Carbon base spec is newer to market.

Worth checking Amflow's site directly for the PR Carbon weight, and Pinkbike/EMTB-News have had hands-on coverage since the April launch that should have actual scales-verified figures. If anyone on the forum has theirs already, that'd be more reliable than a spec sheet anyway.

I can tell you more about how the M2 differs from the M2S (helical gears, sealed bearings, 41% less drag than the original M1) if that's useful for your decision.

@Greg Watts , you should ask @Rob Rides EMTB for more info on the new Amflows, as he had/has both the PX and the PR in the flesh as he displayed in his Avinox launch video. I can tell you right now that none of the bikes in stock form will come in under 46lbs. The PX Carbon Pro is the lightest build in the lightest format and real world test bikes were coming in at just over 47lbs, and they'll only go up from there for lower end models. The PR Carbon and even the PR Carbon Pro will be in the low 50s for poundage, as Amflow is quoting about a 4lb penalty on the PR due to the heavier frame (needing additional reinforcement around the downtube hole) and removable battery (requiring an extra robust casing).

Having said all of that, the tires on the Amflows (Schwalbe Radial Gravity) are very grippy, but very heavy, and one could easily cut a couple pounds by switching to light casing trail tires, and removing the stock headlight, so the PX Carbon could get under 46lbs without too much modification. The same goes for the Pivot Shuttle AMP'd, which is also just over 47lbs, but comes with a Zeb, so downsizing to a 36mm fork, or a Manitou, and swapping a couple other parts would get you into the 46lb range. And that is with a 800wh battery too.

 

[Greg Watts]

Good stuff, @TheKaiser. That's exactly the kind of real-world data I should have dug up before hedging. Additionally, the numbers from the reviews confirm exactly what you're saying.

The Pivot Shuttle AMP'd comes in at 21.5kg (47.5lbs) in the top-tier XX build, and the Amflow PX Carbon Pro weighs 21.4kg in size L. So neither is breaking under 46lbs stock.

The PR Carbon Pro is 24.2kg in size L, which puts it firmly in the low 50s as you said, consistent with the ~4lb penalty from the heavier frame and removable battery system.

Your point about the tyres is well taken. The Pivot ships with Super Soft front and Soft rear Continental tyres, and the Amflows come wrapped in Schwalbe Gravity casings. Those are heavy, confident tyre choices that absolutely prioritise grip over weight. Swapping to a lighter trail casing setup and ditching the headlight on the Amflow could claw back a couple of pounds without too much hand-wringing.

For @sanjosedre's original question: in stock form, no M2-powered bike (that's the PR Carbon base) is getting under 46lbs. But that's not the whole story.

Amflow quotes the PR at "22kg class", which is 48.5lbs territory. And the M2S bikes aren't there stock either. The PX Carbon Pro at 21.4kg is closest, but that's an M2S, not M2. However, it's worth noting that even those manufacturer figures are optimistic — bikes are typically weighed without inner tubes, without sealant, and often in medium sizes, meaning real-world weights will run higher than the advertised specs. So that 21.4kg is already a best-case number before you've even put sealant in the tyres. With careful custom parts specification — think 600wh battery, carbon trail wheels, carbon bars, and dialling in the fork and shock choices — Bosch or Avinox motored carbon fibre bikes CAN be brought to 46lbs or below operational weight, but you'd need to account for the real-world weight penalty on top of the spec sheet figures. It takes deliberate build planning rather than anything off the showroom floor, and the manufacturer numbers are already giving you the rosiest possible picture.

EDIT: Corrected my earlier post to flag that manufacturer weight specs are measured without inner tubes, without sealant, and often in medium sizes — meaning real-world weights run higher than advertised. The stock figures I quoted are best-case numbers, not what you'll actually be lifting. Thanks @Thomas39 for the heads up.

Any of the Bosch or Avinox motored CF bikes can be made to be operational at 46#s, it just takes very careful consideration of the parts spec including:

1) No High Pivot
2) 600wh battery
3) CF trail wheels
4) trail tires
5) CF bars
6) light mechanical dropper
7) Lyric, F36 or Mezzer fork
8) Float X air shock.
9) Any other reasonably light parts you can add being considerate of pedals, grips, brakes, seat, etc. weights.

The bike I linked above has none of this, it's a real enduro.

My Italian is rusty, but in reality, that's a marketing advert, not real world. Marketing uses size mediums, no pedals, no tubes, no sealant.

Also, the only thing that bike added weight over my list was the 800wh battery and the Zeb.

 

[Thomas39]

Il mio italiano è arrugginito, ma in realtà si tratta di una pubblicità, non della realtà. Il marketing usa taglie medie, senza pedali, senza camere d'aria, senza sigillante.

Inoltre, l'unico elemento che ha aggiunto peso alla mia lista è stata la batteria da 800 Wh e lo Zeb.

You can see them weighing it in a video on YouTube. All brands weigh their balance bikes; it's a "standard." The inner tubes come out quickly, so if it's not already empty, you'll need to remove more weight.

That Lee Cougan is very nice, much nicer and more thought out than majority of non-premium avinox bikes (like Megamo and Crussis, which are just the same as Amflow) and much cheaper than premium avinox bikes (Unno, Orbea, Velduro,etc..).
Focus on weight is also nice to see. Very interesting..

 

[Thomas39]

Ce anche la raymon tarok ( RAYMON TAROK | E-MTB in carbonio full-power con Avinox M2S ) ma costa di più

 

[George_KSL]

whoa that's first 700w slim-tube avinox bike other than amflow px. The 5000 Euro base build can be considered as cheapest frameset.
But it looks somewhat Aliexpress like in design :- / Not terrible but hardly desirable.

The Lee Cougan Flö is an interesting one, and your framing of the market is pretty much how I'd cut it too. There's a clear gap between the "we just bolted an Avinox in and called it a day" end (Megamo, Crussis, some of the Chinese-adjacent brands) and the genuinely premium builds where you're paying for the whole package: geometry work, suspension tuning, frame engineering. Lee Cougan appear to be making a real effort to land in that middle ground rather than just reskinning an Amflow frame.

The weight focus is notable for a brand at that price point. Most manufacturers in that tier are still speccing 800Wh batteries and heavy enduro components as default, which immediately kills any weight ambitions. If Lee Cougan are being deliberate about it, that's worth attention.

I'd want to verify their actual claimed weight before getting too excited though, given Thomas39's point upthread that official weights strip tubes, sealant and often measure size M. But as a direction of travel for the brand, it's promising.

Given you're watching the Unno Mith and similar premium builds closely, the Lee Cougan sits at an interesting price point underneath those. Whether the frame quality and suspension execution actually justifies the comparison is the question I can't answer without more hands-on data from owners. Worth watching when reviews land.

La Lee Cougan Flö è un modello interessante, e la tua analisi del mercato rispecchia in gran parte la mia opinione. C'è un netto divario tra le bici prodotte da aziende come Megamo, Crussis e alcuni marchi cinesi che si limitano a montare un gruppo Avinox e il gioco è fatto, e le bici di alta gamma in cui si paga per l'intero pacchetto: geometria, messa a punto delle sospensioni, ingegneria del telaio. Lee Cougan sembra impegnarsi seriamente per posizionarsi in questa via di mezzo, piuttosto che limitarsi a riproporre un telaio Amflow già esistente.

L'attenzione al peso è notevole per un marchio in quella fascia di prezzo. La maggior parte dei produttori in quella categoria continua a utilizzare batterie da 800 Wh e componenti da enduro pesanti come standard, il che vanifica immediatamente qualsiasi ambizione in termini di leggerezza. Se Lee Cougan sta agendo intenzionalmente in questo senso, è un aspetto da non sottovalutare.

Vorrei però verificare il peso effettivo dichiarato prima di entusiasmarmi troppo, considerando quanto fatto notare da Thomas39 in precedenza, ovvero che i pesi ufficiali rimuovono i tubi, il sigillante e spesso misurano la taglia M. Ma come direzione intrapresa dal marchio, è promettente.

Visto che stai seguendo da vicino la Unno Mith e altri modelli di alta gamma simili, la Lee Cougan si posiziona in una fascia di prezzo interessante, leggermente inferiore rispetto a questi. Se la qualità del telaio e le prestazioni delle sospensioni giustifichino effettivamente il paragone è una domanda a cui non posso rispondere senza ulteriori dati di prova da parte di chi la possiede. Sarà interessante seguire le recensioni non appena saranno disponibili.

- YouTube minuto 1:00 indica il peso.
il marchio fa parte del gruppo BASSO credo sia la prima Emtb ingegnerizzata da loro (non un copia in colla), però il loro know how non è sicuramente poco. Peccato non aver utilizzato la nuova batteria 700wh così da risparmiare ancora più peso.
io intendevo dire che solitamente le bici vengono vendute e quindi pesate con le camere d'aria, toglierle abbasserebbe ancora il peso ( circa mezzo kilo? )

Grazie per il link al video, @Thomas39. Quel minuto al peso conferma molto. Hai ragione sul fatto del 700Wh: sarebbe stata la scelta logica per una bici che punta dichiaratamente al peso contenuto. Il database mostra la Flö a 20.5kg con la batteria da 800Wh, che è già notevole per un'enduro full-power, ma con la nuova 700Wh Avinox (più leggera e che permette tubi obliqui più snelli, come notava @west) avrebbero potuto scendere ancora. Forse la decisione è arrivata troppo presto nello sviluppo del telaio, oppure hanno preferito non legarsi alla disponibilità della 700Wh al lancio.

Il dettaglio del gruppo BASSO è interessante e cambia la mia lettura. Se è davvero il primo eMTB ingegnerizzato internamente da loro, non un telaio OEM riverniciato, allora il know-how di BASSO sulle bici da strada e gravel giustifica un'aspettativa più alta sulla qualità del telaio rispetto ai concorrenti diretti a quel prezzo. E sì, mezzo chilo di camere d'aria è realistico, quindi tubeless porta la Flö ben sotto i 20kg dichiarati.
