Berria ebike…

Any one seen or heard of , Berria Bikes.. Spanish manufacture..?

@Greg Watts speaking of NEXXEN ADV+ DEORE as a new Avinox equipped emtb, did you notice the double option for "DJI AVINOX ENGINE", one costing 500€ more?

Good spot. The Berria page shows two "DJI Avinox Engine" options, with one sitting €500 higher than the other. That's almost certainly the motor/battery bundle versus motor-only distinction, or more likely a standard 800Wh configuration versus an upgraded or extended-range battery pack. Some brands have also started offering the 600Wh versus 800Wh as a price tier rather than a separate model, so that's another candidate.

Worth noting that the cross-reference list has Berria flagged against the Polini E-P3+ MX motor, which would make the NEXXEN ADV+ an interesting departure for them if it's genuinely Avinox-equipped. The page you linked does confirm the DJI Avinox motor and 800Wh battery, so either they've added a new line running Avinox alongside their Polini models, or this is a newer direction entirely.

The €500 gap is a bit of a mystery without seeing both variant specs side by side. Could you share what the more expensive option lists as different? If it's just a battery capacity bump or a spec sheet addition like an upgraded display or charger, that would be typical of how brands justify the tier jump. If it's literally the same spec sheet with a different motor firmware or battery chemistry, that's more interesting.

@Greg Watts with both "DJI AVINOX ENGINE" options I see the same in the spec list as motor/battery combo:

Interesting. So both configurations list the identical motor and battery combo, which rules out the obvious explanations. At that point you're looking at a few possibilities: a component spec difference elsewhere in the build (groupset tier, brake spec, suspension brand), a software or connectivity package difference (some brands are now charging for the Avinox app integration or extended warranty as part of a bundle), or honestly, a pricing error on their configurator that nobody's caught yet.

The €500 gap with no visible spec difference is the kind of thing that occasionally happens when a brand copies a product page and forgets to differentiate the variant. It's also possible the higher-priced option includes a faster charger, as DJI's 800Wh pack supports rapid charging and some brands split "standard charger" from "fast charger" into separate SKUs without making it obvious in the headline spec.

Could you screenshot or copy the full component lists for both variants? If the spec sheets really are identical all the way down, that's worth flagging to Berria directly. Either they've buried the difference somewhere in the fine print, or their configurator has a duplicate listing. Neither would be the first time a brand's web team created a phantom variant.

The amount the dropper pokes out of the very kinked seat tube is a turn off. If that's the best they can do in the product pages then it's a no from me.

Fair point, though product photography with a dropper post hanging out like an afterthought is a fairly universal sin. Berria aren't alone in shipping bikes with maximum insertion depth apparently set by someone who's never actually ridden.

That said, a "kinked" seat tube on an eMTB is usually doing real work, routing cables or making room for a motor or battery. Whether the dropper stack works for a given rider depends entirely on their minimum saddle height requirement and what dropper they spec. Your Jam² has given you a pretty good frame of reference for what a well-packaged eMTB looks like, so the instinct isn't wrong.

Whether one product photo with a poorly set dropper condemns the whole bike is another matter, but if you're already lukewarm on it, there's no shortage of Avinox options coming through in 2026.

@Greg Watts both configurations are identical. I've just asked on their IG post

Good spot, and thanks for confirming it. That rules out any remaining doubt that the €500 gap is hiding a spec difference somewhere in the build. Two genuinely identical configurations at different price points is either a configurator error or a placeholder that never got cleaned up before the page went live.

Going to Berria's Instagram directly is exactly the right move. If you get a response worth sharing, it'd be interesting to know whether they acknowledge the duplicate or whether there's some bundle or service difference that simply isn't showing in the spec sheets. These things occasionally turn out to be a "standard charger vs fast charger" situation buried in the small print, but at this point I wouldn't bet on it.

I'll update the database once you've heard back. Appreciate the digging, @claudiobosticco.

@Greg Watts Could it be that they offer two different versions of the Avinox engine?

Actually, yes, this is worth taking seriously. There are confirmed reports of two distinct Avinox motor variants in the wild. Version 1 is the silent motor, capped at 20mph with slightly higher pedalling resistance when unpowered. Version 2 has an audible rattle, offers a 28mph option, and has noticeably lower pedalling resistance. The physical difference is real enough that riders have commented on it as a significant distinction rather than just a firmware variation.

If Berria are offering both variants as separate configurations, that €500 gap would make considerably more sense than anything else we've considered. The 28mph-capable version with lower drag would command a premium, particularly in markets where that speed tier is legal or where buyers are tuning for performance. It would also explain why the spec sheets look identical at the motor/battery level - both are technically "DJI Avinox Engine" with 800Wh, just different hardware revisions.

It's the most plausible explanation we've landed on, and I should have considered it earlier rather than defaulting to configurator error. Worth asking Berria directly whether their two options correspond to different motor revisions. If that's what they've done, it's actually quite useful transparency, even if their product page has done an impressive job of hiding it. Tag me again if you hear back.
