MotoRadds vs. COREmounts: What You Give Up Buying a Chin Mount on Etsy [2026]

August 2026 · ~11 minutes

First, a disambiguation, because this one trips people up.

COREmounts — the helmet chin mount brand — does not have a website. It's a German seller trading on Etsy and eBay only, run by one person out of Bergheim near Cologne. If you searched for coremounts.com you found a woodworking business in Mississippi that makes tree-core mounts for dendrochronology, and coremount.co.uk is a UK handrail manufacturer. Neither has anything to do with motorcycles.

The real COREmounts sells around 173 listings — 154 motorcycle helmet mounts and 17 mountain-bike ones — each modelled for a specific helmet, at €19.90 (roughly $30 landed for a US buyer). They're 3D printed from carbon-fibre-reinforced filament, made in Germany, and they say all of that plainly on the listing.

We make a competing product, so treat this as a manufacturer comparison. What we'll try to do is be precise about where they're genuinely better than us — and there are a few places, one of which is a category-leading move on customs — and precise about the one thing we'd want any buyer to read before ordering, which is their own liability language.

TL;DR

Short answer: for a European rider whose helmet they cover, COREmounts is a reasonable buy at a good price from someone who's transparent about how they make things. For an American, and for anyone who cares what happens after a mount lets go, the gap is warranty: they publish none, and their listings state in German that the mount is "kein sicherheitsrelevantes Bauteil" — not a safety-relevant component — and that it must be checked for secure seating before every ride.

How we evaluated these

Nine criteria, weighted for someone spending real money on a part that holds a camera at speed:

1. Price, on the sticker
2. Fit on a supported helmet
3. Fit on an unsupported helmet
4. Materials and manufacturing transparency
5. Installation guidance — prep, cure time, adhesive spec
6. Warranty — what's actually promised
7. Returns, and who pays
8. Landed cost and how customs is handled
9. Independent evidence that it lasts

At a glance

COREmounts, honestly

This is a one-person business and it's worth saying that plainly, because it cuts both ways. Dennis Barow has been trading since 2023, has taken roughly 2,500 orders between Etsy and eBay, holds a German VAT number, and answers his own email. There's no company structure, no employees, no press coverage, no website.

Catalogue: helmet-specific only, with genuinely good European coverage — NEXX, HJC, Ruroc, Schuberth, John Doe, Simpson, Caberg, AGV, Nolan, Leatt, LS2, Scorpion, Shoei, O'Neal, Airoh and Fox, plus Arai, Shark, Alpinestars and POC in the eBay listings. Nolan, Caberg and John Doe in particular are brands most of the North American category skips entirely.

What you get: the Single is the mount, mounting hardware and instructions. The Set adds long, medium and short arm attachments plus an extension and screws — so you set camera angle by swapping printed arms rather than adjusting a hinge. (If the listings read oddly, that's machine translation: the German Aufsatz, meaning attachment piece, comes out as "essay.")

Pricing on Etsy for a US buyer: €19.90 list, which lands between roughly $30.36 and $36.51 at checkout depending on the listing, with $42.56 for the set. Shipping is $18.17, free over $35 — so the cheapest single sits just below the free-shipping threshold and the set clears it. Check the total on your specific listing.

What COREmounts genuinely does better

They tell you what the mount is made of. "High-precision 3D printing from carbon fiber reinforced polyester." That is more material transparency than several much larger competitors in this category manage — a number of well-known brands publish nothing at all about their polymer or process. We'd rather buy from someone who says "3D printed carbon-filled filament" than someone who says nothing, and we'll defend that position even though it's a competitor's.

Etsy prepays US import duty at checkout. This matters more than it sounds. Since the US suspended the $800 de minimis exemption in August 2025, buying a small item direct from a European seller usually means duty plus a carrier brokerage fee at the door. Their listing states that "for US deliveries, Etsy policy requires that import duties and fees are included in the checkout price" — so on an Etsy order you pay one number and nothing arrives collect. That's a real structural advantage over European brands selling from their own webshops, and it's why their US price runs above a straight euro conversion.

Price. €19.90 for a helmet-specific mount is the cheapest credible model-specific option we've found — roughly $30–$37 at US checkout depending on the listing, with import fees already included.

Fast shipping, and people say so. "As described and lightning-fast shipping. Highly recommended" (Nirah). US delivery estimates run about 1.5–2 weeks, which is respectable from Germany.

Real customer support from an actual human. "Perfect mounting on my Shoei Glamster and great support" (Fabeeahn). "Customer service is very nice and understanding, I recommend!" (Tomasz). When a one-person shop is responsive, it's genuinely responsive.

It survives abuse. "Nice product, survived several off-road crashes with no issues" (Dmytro, 5 stars).

The Set is a smart bundle. Three arm lengths plus an extension for $42.56 gives you more angle options out of the box than most competitors include.

They publish designs on Cults3D. If you own a printer, some of their models are available there. Very few brands in this space will do that.

European coverage we don't match. Nolan, Caberg, John Doe, Airoh, O'Neal. If you ride one of those, they may be your only helmet-specific option.

Where COREmounts falls down

There is no warranty. At all. This is the whole argument, and it's in their own words. In place of a warranty, the listings carry a liability notice. It's written in German; the translations below are ours.

"Die Nutzung erfolgt auf eigene Verantwortung. Wir übernehmen keine Haftung für Schäden, die durch unsachgemäße Montage, nicht bestimmungsgemäße Verwendung oder äußere Einflüsse entstehen." — "Use is at your own risk. We accept no liability for damage arising from improper installation, use other than as intended, or external influences."

"Die Action Cam Halterungen sind vor jeder Fahrt auf einen festen Sitz zu prüfen." — "The action cam mounts must be checked for secure seating before every ride."

And, in the product notice:

"Dies Produkt wurde im 3D-Druckverfahren hergestellt und sind kein sicherheitsrelevantes Bauteil. Materialeigenschaften können durch Hitze, Kälte, UV-Strahlung, Vibrationen oder unsachgemäße Nutzung beeinträchtigt werden." — "This product was manufactured by 3D printing and is not a safety-relevant component. Material properties can be impaired by heat, cold, UV radiation, vibration or improper use."

Read that as a buyer. A part that lives on the outside of your helmet, in direct sun, through freezing mornings and summer heat, under constant engine vibration — and the manufacturer is telling you that heat, cold, UV and vibration can affect its material properties, that you should check it before every ride, and that if it fails, that's your problem. That's an honest disclosure and we'd rather they made it than didn't. But it's also a description of exactly the operating environment the product is sold for.

(EU consumers do retain statutory conformity rights regardless of what a listing says, so a German or French buyer isn't entirely without recourse. A US buyer's practical remedy is Etsy's or eBay's own buyer protection, not the seller's.)

14 days on Etsy, and you pay to send it back. "Buyers are responsible for return shipping costs," and cancellations aren't accepted. eBay gives 30 days, also buyer-paid. From the US, return postage to Germany on a $30 item is a meaningful fraction of what you spent — and since the mount bonds with VHB, test-fit-and-return isn't realistic anyway.

No cure time, no minimum temperature, no adhesive grade. You get a 3M VHB pad and an alcohol swab. No grade, no primer, and — the one we'd genuinely push on — no instruction to wait before riding. VHB builds strength over hours, not minutes.

Adhesive failure is the recurring complaint. From their own Etsy reviews: "The mount does not fit my helmet properly… it fell off. When I contacted the seller, they were incredibly dismissive, essentially telling me it wasn't their fault" (1 star). And: "The mount itself fits Spark 2, but that's the end of positives for me. Adhesive started to come" off after one ride (3 stars). A third, at four stars, reports that the mount fits perfectly but the camera holder rattles slightly. Adhesive complaints are endemic to this whole category, ours included. Worth noting in fairness: the seller replied publicly to that one-star review disputing that the part was defective but stating they had offered a refund, and replied to the rattling complaint saying they would look into it and improve the design.

The independent evidence base is very thin. 125 Etsy reviews and eBay feedback. No Trustpilot profile exists. No Reddit threads, no ADVrider discussion, no YouTube reviews, no press. For a durability-critical part, nobody outside their customer base has ever tested one and reported back.

No website, no company. Marketplace-only means your recourse runs through Etsy or eBay rather than a company with a returns department. If Dennis stops trading, your mount is unsupported and unreplaceable.

Camera compatibility is stated by interface, not by model. "GoPro Hero, DJI Osmo Action, Insta360 Ace, other action cams with standard GoPro mount" — no model matrix. Fine for anything with a two-prong finger, but not a guarantee for cameras using a proprietary quick-release.

Best for: EU riders whose helmet is in their catalogue, price-driven buyers, and people who ride European brands nobody else covers.

MotoRadds, honestly

We've made motorcycle camera mounts since 2017, from Gilbert, Arizona. First flexible-core prototype April 2020, FLEX Classic in 2021, FLEX Slim now.

FLEX Slim, $34.95: a steel core skeleton inside a vibration-damping silicone overmould, with an injection-moulded polycarbonate camera platform and four stainless steel screws. Independent measurement puts it at 34 g against our published 65 g — we'd rather flag the discrepancy than quietly use the flattering number. Shape it to your chin bar, prep the surface, bond with genuine 3M VHB, wait 24 hours.

Helmet-specific FLEX mounts, $34.95: polycarbonate with a steel core, alloy screws, silicone finish. Shoei, Arai, AGV, HJC, Scorpion, Bell, Nexx, KYT, LS2, Shark, Sena, Klim, Fox, 6D, Alpinestars, Harley-Davidson and more.

The rest of the bike: FLEX Classic ($24.99) for MX visor peaks, windscreens and fairings; EdgeLock ($29.99), an adhesive-free clamp for 2–4 mm edges; X-Pand (from $54.99) for fork stems and bar ends; in-helmet mounts for the DJI Osmo Nano and Insta360 GO 3S; ND filters, cages and vertical adapters.

What we do better

There is a warranty, and it's for life, wherever you are. Manufacturing defects and premature wear through normal, intended use — separation, warping, degradation — covered for the life of the mount, worldwide, with proof of purchase. A replacement ships free with a small shipping fee ($4.50 within the US, $15 international, per our FAQ). That's a different relationship from "inspect it before every ride and you waive all claims."

We don't describe the product as non-safety-critical and leave it there. Ours is a load-bearing part and we treat it as one: steel core, published construction, a stated cure time, and a policy that covers premature wear.

Your helmet doesn't need to be in a catalogue. The FLEX Slim is the whole point. Discontinued lid, obscure brand, a shell nobody's modelled, a bicycle or snowmobile helmet — you bend it to what's actually in front of you. The Loam Wolf: "You would be hard pressed to find a helmet this would not be compatible with."

The mount survives a helmet change. A rigid model-specific part is scrap the day you buy a new lid. A FLEX Slim transfers with a fresh adhesive pad.

A steel core and a silicone seal. The silicone damps vibration at the interface and conforms across texture to create bond area a rigid printed part doesn't get on an irregular surface — and it doesn't have layer lines to begin with.

We publish a cure time. 24 hours. It's the single most important instruction in the box.

Three warehouses, so most orders never cross a border. Arizona, Czechia and Australia. No customs, no brokerage, no intercontinental return postage — and returns go to whichever warehouse serves you. A European buyer isn't crossing a border with us any more than with them; an Australian buyer isn't crossing one with us but would be with them. Most of the time, our website won't let you check out if it's not in stock at your service warehouse.

Nine years and a public review record. The Loam Wolf, BeginnerBiker (4.5/5, tested on a Shoei Neotec), Masqueride, Electronikz (8.6/10), plus motovlogger video coverage. Trustpilot 4.8/5 across 106 reviews. You can read outside opinions before spending.

A company to complain to. An Arizona address, an email that reaches a support function, and a published returns process.

Where we fall down

We're more expensive. $34.95 against roughly $30–$37 landed, and $42.56 gets you their whole arm set. If price is the deciding factor, it isn't us.

They're more specific about their material than we are about ours. We publish steel, silicone, polycarbonate and stainless; they publish "carbon fibre reinforced polyester." Neither of us publishes a resin grade, a VHB grade, or third-party pull-test data. Fair criticism of both.

They cover European helmet brands we don't. Nolan, Caberg, John Doe, Airoh, O'Neal.

They publish models on Cults3D and we don't. If you own a printer and want to make your own, that's an option we simply don't offer.

Sharply peaked chin bars are a real limitation. A customer: "the mount didn't work for me, my helmet and chin protector was too pointy for it to adhere properly." Historically the AGV Pista, Corsa and K1. We now make a Pista-specific mount, but check the helmet-specific range if your lid has a knife-edge centre ridge.

Removal is hard. The Loam Wolf notes the bond is strong enough that release takes heat and patience. Position carefully the first time.

Screw-down is slower than a clip. BeginnerBiker: "My only very minor bugbear is the slight extra faff of unscrewing the GoPro on/off the mount, vs the quick slide-in clip of the old design."

Adhesive has failed for some customers. Reports of bonds loosening in the first couple of months, and where we could trace the cause it was surface prep. Degreasing and a full 24-hour cure are not optional.

We ship in 5–7 days domestic and have had customers report longer.

Best for: US riders, anyone who wants one mount that fits nearly any helmet, and anyone who wants a warranty on the part holding their camera.

Head to head

1. Price

€19.90 list, roughly $30–$37 landed with duty prepaid, against $34.95. The set at $42.56 includes three arm lengths. On sticker, they win.

Winner: COREmounts.

2. Fit on a supported helmet

A rigid part modelled to your specific shell sits flush without shaping, and their reviews back it up: "fits perfectly," "perfect mounting on my Shoei Glamster."

Winner: COREmounts.

3. Breadth of helmets covered

15-odd brands on a marketplace catalogue, against a moldable mount that fits nearly every helmet on the market and needs no catalogue at all. Also no wrong-model risk, which matters more when a return crosses a border.

Winner: MotoRadds.

4. Materials transparency

They name the material — carbon-fibre-reinforced polyester — and disclose the process and its limitations. We name our construction. Both of us stop short of grades and test data. Call it even, and note that both of us beat several larger competitors who publish nothing.

Draw.

5. Installation guidance

A VHB pad and an alcohol swab against a prep pad, a published 24-hour cure and clear surface-prep instructions. Neither publishes a VHB grade.

Winner: MotoRadds.

6. Warranty

Lifetime coverage including premature wear, against no warranty and an explicit waiver of claims. This is the widest gap in any comparison we've published.

Winner: MotoRadds, decisively.

7. Returns

30 days against 14 on Etsy, both buyer-paid. For a US buyer ours stays domestic and theirs crosses the Atlantic. For an EU buyer both stay inside the EU — Germany for them, Czechia for us — so it comes down to 30 days against 14.

Winner: MotoRadds — domestic for US buyers, and twice the return window everywhere.

8. Landed cost and customs

Etsy prepaying US duty is genuinely the best customs handling of any overseas seller in this category, and we'll give them full credit — for a US buyer they remain the best-handled overseas option we've reviewed. But domestic still beats prepaid-import on transit time and on the return path. For an EU buyer neither of us charges customs, since we fulfil European orders from Czechia, so the category cancels out.

Winner: MotoRadds for US buyers. A draw in the EU.

9. Independent evidence

125 Etsy reviews and eBay feedback, with no Trustpilot, no forum threads and no video reviews, against nine years of published hands-on coverage.

Winner: MotoRadds.

Running score: MotoRadds 6, COREmounts 2, draw 1. For an EU rider category 8 becomes a draw too, since we fulfil European orders from Czechia and neither of us charges customs — so it lands at MotoRadds 5, COREmounts 2, with two draws. Their genuine wins are price and per-model fit, and those hold on both continents.

So which one should you buy?

Buy COREmounts if:

• You're in the EU, your helmet is in their catalogue, and price is what's driving the decision
• You ride a Nolan, Caberg, John Doe, Airoh or O'Neal
• Price is the deciding factor and ~$30 beats $34.95 for you
• You want three arm lengths in the box for angle adjustment
• You'd rather buy from someone who tells you plainly it's a printed part than from someone who tells you nothing
• You own a 3D printer and want to use their published model
• You're comfortable with no warranty and checking the mount before rides

Buy MotoRadds if:

• You're in the United States — or in the EU, where we ship from Czechia and you pay no customs either
• You want warranty coverage on a part that holds a camera at 70 mph
• You want one mount that fits nearly any helmet — including a discontinued lid or a brand they don't cover
• You'll own another helmet within this mount's lifetime
• You want a 30-day return that doesn't cross an ocean
• You want a published cure time and proper installation guidance
• You want to read independent reviews before you buy
• You're mounting more than one camera and want windscreen, fork or in-helmet parts from one brand

The verdict

We want to be fair about what COREmounts is doing well, because two things stand out. They tell you exactly what the part is made of and how it's made, which is more than several far bigger companies in this category will do. And selling through Etsy means US import duty is prepaid at checkout — which, since de minimis ended, makes them the least painful overseas purchase in this whole comparison set. Neither of those is nothing.

But the thing you're buying is a bracket that holds a camera to your helmet while you ride, and the seller's own listing says — in German — that it is not a safety-relevant component, that heat, cold, UV radiation and vibration can impair its material properties, that it must be checked for secure seating before every ride, and that use is at your own risk. That's an honest disclosure and we'd rather have it than not. It is also, read plainly, a description of a part sold without a warranty into exactly the environment the seller has told you may degrade it.

Our answer to that is a steel core, a silicone seal, a published cure time, and lifetime coverage for premature wear that's included in the price rather than disclaimed away. For a few dollars more, from Arizona, with a 30-day return and outside reviews you can go and read.

If you're in Europe, your helmet is on their list, and the five-dollar difference is what matters, we'd understand the other choice — though we fulfil EU orders from Czechia too, so you're not paying customs with us either, and you'd be trading a lifetime warranty for that fiver. If you're in the US, we don't think it's close.

FAQ

Is coremounts.com the helmet chin mount company? No. coremounts.com is a Mississippi woodworking business that makes mounts for tree-core samples, and coremount.co.uk is a UK handrail manufacturer. The chin mount brand COREmounts has no website — it sells on Etsy (shop name COREmounts) and eBay (seller coremounts) only.

Does COREmounts offer a warranty? No. There is no warranty statement on any of their listings. Instead they publish a German-language liability notice stating that use is at the buyer's own risk, that they accept no liability for damage from improper installation, unintended use or external influences, and that the mount must be checked for secure seating before every ride. EU consumers still have statutory conformity rights regardless; US buyers are relying on Etsy or eBay buyer protection. MotoRadds covers its mounts for life with proof of purchase.

Are COREmounts 3D printed? Yes, and they say so. Their listings state "high-precision 3D printing from carbon fiber reinforced polyester." Carbon-fibre-reinforced filament is chopped fibre in a printed plastic part, not a composite laminate. Credit where it's due — a lot of brands in this category are far less forthcoming about their process.

Will I pay import duty buying COREmounts from the US? Not separately. Their listing states that Etsy policy requires import duties and fees to be included in the checkout price for US deliveries, which is why the USD price runs above a straight euro conversion. That's better handling than most overseas sellers. On eBay it is not prepaid — their listing states that under US customs policy the buyer pays import fees to the postal courier before delivery. Trade rules change; verify current requirements.

How long does shipping take from Germany? Roughly 1.5 to 2 weeks to the US based on their published estimates. Shipping is $18.17, free over $35 — note the cheapest single sits below that threshold and the $42.56 set clears it.

What's the return window? 14 days on Etsy, 30 days on eBay, buyer pays return postage in both cases, and cancellations aren't accepted. From the US that means transatlantic postage on a $30 item. MotoRadds gives you 30 days to a US address. With either brand, once the adhesive liner is peeled, assume you own it.

Which cameras work with each? COREmounts lists GoPro Hero, DJI Osmo Action, Insta360 Ace and "other action cams with standard GoPro mount" without a model matrix. MotoRadds covers GoPro Hero 5 through 13, Insta360 X3/X4/X5, Ace Pro and Ace Pro 2, GO 3 and 3S, DJI Osmo Action 3 through 6, Osmo 360 and Nano, and makes dedicated in-helmet mounts and vertical adapters. MotoRadds mounts your camera on a fingertab joint rather than requiring a separate buckle clip, and that joint is included in the box at no extra cost.

How long should I wait before riding after installing? 24 hours, minimum, with either brand. COREmounts doesn't publish a cure time; we do. 3M VHB builds strength over hours and needs a warm, clean, degreased surface. Never bond outdoors in freezing conditions.

Can I move the mount to a new helmet? With a MotoRadds FLEX Slim, yes — heat to release, clean, fresh VHB pad, reshape. With a COREmounts mount, no: the geometry fits one shell.

Are there independent reviews of COREmounts? Not that we could find. They have 125 Etsy reviews at 4.8 and strong eBay feedback, but no Trustpilot profile, no Reddit or forum threads, and no YouTube reviews. That's a genuine gap for a part where failure means a camera in the road.

Do I pay customs buying MotoRadds in Europe? No. We fulfil EU orders from a warehouse in Czechia, so a European order is EU-domestic — no duty, no brokerage fee, no customs hold — and returns stay in Europe. Our lifetime warranty applies worldwide. Most of the time, our website won't let you check out if it's not in stock at your service warehouse.

Is a one-person Etsy shop a bad thing to buy from? Not inherently — small sellers often give better support than big ones, and COREmounts' reviews repeatedly praise exactly that. The trade-off is what happens if they stop trading, and what recourse you have when there's no warranty and the marketplace window has closed. Weigh that against saving five dollars.
