Muc-Off's Clever New Product Allows You to Hide an Apple AirTag in Your Wheel

May 13, 2022 at 14:24
by Sarah Moore  

Muc-Off has introduced a new way to stow an Apple AirTag on your bike, completely hidden and not easily removed by bike thieves. The new Stealth Secure Tag Holder is a covert tracking solution, hidden inside the tire of a tubeless-compatible mountain or gravel bike.

According to a study from Direct Line Insurance, in the five months between April and August 2020, there were more than 110,000 bike thefts in the UK. As for the United States, bike registration specialists 529 Garage reported that there are over two million bike thefts every year. Locks, alarm systems, and insurance have historically been the best ways to protect your prized possession, but with the release of the Apple AirTag in April of 2021, we've seen an additional way to keep tabs on your bike.

There have been a couple of different companies that have released products that allow you to hide an Apple AirTag on your bike, including the Ninja Mount that hides the AirTag under your saddle and Project4AGZE's holder that mounts under your water bottle. Muc-Off also has a similar product called the Secure Tag Holder which allows you to install a tracker to your frame using the bottle cage mounting holes, so you can track down your bike down in the event of theft and locate it.

bigquotesTechnologies like the Apple Airtag can be a great defense against would-be bike thieves. This is what led us to develop our Tag Holders, we wanted to give riders secure and thief-proof ways of fixing the tracker to their bikes. The newest offering – the Stealth Tubeless Tag Holder - is a completely unique undercover solution unlike anything we have seen on the market so far. We will continue to embrace emerging technologies to enhance every rider experience, as we continue our exciting program of innovation in the future. Alex Trimnell, CEO at Muc-Off

The Apple AirTag (not included) on the Stealth Secure Tag Holder is housed in a protective, 3-part silicone and rubber tubeless valve mount and supplied with a range of tubeless valve bases, so you can ensure an airtight seal is achieved against the rim when installing inside a tubeless tire.

Also built-in to protect the rim and the AirTag from high-impacts is a sacrificial stem that compresses and rebounds under extreme loads. Although the holder will absorb impacts, Muc-Off says it is secure to the valve with a durable stem mount which allows sealant and air to flow through the valve as usual and will not rattle inside the rim and tire.

The Apple AirTag itself works by allowing users to track any item from their phone, using the Find My app. Once activated, any item to which the tag is connected appears on the radar within the app, so you can track down your bike by looking on the map.

If the thief has an iPhone, their iPhone will notice when an AirTag is separated from its owner and is travelling without you and send the thief an alert. This is an anti-stalking mechanism. After a while, if the thief hasn't found the tag, it will start playing a sound to show where it is. Regardless, the AirTag hidden in the wheel should give you more time to alert the authorities and hopefully recover your bike than other options.

The Stealth Tubeless Tag Holder retails via Muc-Off distribution network and at for £14.99/€19.99/$19.99 and as part of a kit which includes a set of black Muc-Off 44mm Tubeless Valves for £34.99/€42.99/$44.99.

 I have an AirTag in my wife's purse and I've noticed she's always going to my best friend's house when I'm at work. I think they're planning a surprise party for my birthday! I'm so excited!
  • 69 0
What a coincidence, she has an AirTag on your wallet so she and your best bud know when it's time for them to put the party planning on hold and rush home before you arrive. "Oh hi honey, how was your day? I'm just going to hop in the shower, I'm all sweaty after my run..... again."

 @dlford: While the comedy is not lost on me. I had this exact thing happen to me. AirTag didn't exist at the time tho so I had to use other means to learn about my surprise party planning sessions. haha

 I don’t have anything snarky to say. This is a genuinely good solution to a problem nobody ever wants to confront, and it seems very well thought out.
  • 35 2
 Idk it seems like a cool idea but honestly it would Make me worry so much about the wheel. If they could show a test of it with someone hammering down a trail. I would be all for it

 What happens when u get a flat? U cant ride the bike cause you will smash the airtag.
  • 37 0
 @letitwhip33: We need slow motion huck-to-flat video; I’m sure after enough attempts that could land on the stem section of the rim.

Would probably be a decent accessory for commuter bikes though, which quite frankly are probably more likely to get stolen on a regular basis.

 @naptime: its a last resort, but I have a couple of times over my 37yrs of mtb. in 92 I flatted in a xc race 250metres from the line, I wasnt going to stop & fix it. my 1st ever win was my most memorable.
so no I wouldnt recommend it, but sometimes you just need to get home or at least to civilisation/ mobile reception to bum a lift

 Exactly. That's really good idea in a long time without marketing bullshit everywhere.
  • 5 6
 The thing is, why would anyone want an air tag on their bike in the first place? The things are useless for theft prevention, unless the thief knows it’s there, and they’re useless fir getting a stolen bike back, because the airtag will alert the thief, long before you have a chance to get to them.
  • 2 1
 @FuzzyL: Yeah that's so stupid!! They alert the thief if he has an Iphone and if the thief didn't find the device, it will make a sound just to be sure that he can find it, destroy it and get away with it! We want to find the thief and makes him regret it or at least make him arrested by the police so he doesn't continue with other bikes!

 @Timo82: I’ve had one in my bike for a few weeks now, I’ve ridden and drove around with iPhone buddies, stayed in the same apartments, with the bikes in close proximity, etc, they’ve never been notified that there’s an AirTag near them. I think maybe if you stuck it in their pocket or bag, etc, it might see that as stalking, but if you’re just regularly moving around the tagged thing, then they’ll never know.

 @pbuser2299: Did you have your iPhone with you? Of course there won‘t be an alert if you travel with your airtag.

 The problem is how does the tracker communicate with you?
Does it communicate with your phone? In which case it needs a sim too. If it communicates directly via bluetooth for example, that's pretty useless. Or does it communicate with its own receiver? In which case you can add a bulky receiver and £600 to the cost of the bike.
It's an easy solution to suggest until you consider what it actually involves.

 Why not just stash it inside the frame via the head tube or swat box or bottom bracket openings? Use some double sided tape or something….

With this changing the battery means dismounting the tire…
  • 7 8
 inside the frame will block the signal. Also inside the tire, would destroy a carbon rim if it gets punctured. We need something else still maybe tape to the saddle could work.
  • 25 0
 Gp lama has tested airtage position vs range extensively
1.Inside aluminium stem. Signal completely blocked (useless)
2 inside carbon bb signal distance lowered to 21m
3 onhead of metal seatpost 23m
4 in plastic 3d print bottle cage mount. So basically outside of bike. Best range at 35m ( a bit obvious for the smart thief)

People have successfully recovered bikes by having mounted 2 tags. Thief removed one before taking bike to home location of their own phone and then 2nd tag pinged location

 @naptime: I was hoping that given Find My is a protocol than can be used by other products. I had hoped that the focus would have been on say a Find My compatible stem cap, rather than various holders for Air Tags.
  • 3 1
 @gcrider: Why in would anyone put an RF device inside the BB when they could put it anywhere else? Your signal is blocked on at least 3 sides by metal bearings & the axle. Literally anywhere else inside a carbon frame would be better. Likewise, why would you put it directly on metal seatpost when you can tape it to the saddle shell? Sounds like this Lama character has more spare time than sense.
  • 1 1
 In the bottom bracket was actually under the cat flap beside the bottom bracket in his carbon frame
On top of metal seatpost was not visible to thief but outside of frame ( all shown in his video)
Having it taped to saddle would be easier for thief to spot and remove if the thief was smart ,

 I have it double sided velcro taped to inside of both my E-Bike (Intense Tazer) just out of reach (you need a key to remove the battery), and on my Spaz Enduro it's behind the bottom of the SWAT box. Same double sided velcro tape. No issues and range is perfect.

 I never knew AirTags would alert a person near it that it's been separated from its owner. This pretty much makes them useless as an anti theft device doesn't it unless you instantly know your bike is missing which would rarely be the case?

 Only alerts thief once they get home. And saves location for the owner to view. @Kimura:
  • 15 2
 @Kimura: Before this I thought AirTags were one of the smartest things out there, now I think they are one of the most useless things out there. They literally will tell people that they have/are near something expensive of yours and that you are nowhere to be found. Awesome.

Not knocking this Muc Off product, it's actually quite smart aside from this Apple flub.
  • 17 0
 @gcrider: From Apple:

If someone else’s AirTag finds its way into your stuff, your iPhone will notice it’s travelling with you and send you an alert. After a while, if you still haven’t found it, the AirTag will start playing a sound to let you know it’s there.

So I would say they will know long before they get home.
  • 9 1
 @warmerdamj: that seems like one hell of a design flaw! And apple doesn't give the air tag owner a way to toggle that feature on/off ? Seems very dumb....maybe the a result of anti-surveillance laws? I guess it's a pretty powerful tool for stalkers/criminals who might want to use it for other purposes
  • 50 0
 @rory: Stalking is exactly why they have it make a noise, so somebody cant air tag you then follow you home and kill you.

This is human innovation at its best:

1. Make a really useful device to find lost things.
2, Realize that people are such f*cking pieces of shit they will exploit it to hurt others.
3. Make said device less useful.

 So initial alert sounds when tag is out of range of owner. So all depends on if you park your bike and if you move out of range or the thief moves it out of range. If the thief moves it. They will get alerted. But so will you. Then they will have to remove tag or battery before they get to where they are taking the bike to before you get to them.

 Yes, this is true and is also the reason I have Tiles instead of AirTags mounted under all of my bike's saddles. This is true for ALL devices that use Apple's Find My Network. I reached out to Chipolo, another company that makes an Air Tag competitor that piggybacks off the Find My Network and they confirmed this. Tile FTW. With the Amazon Sidewalk network (pings off of all Alexa and Ring devices, just like the Find My Network pings off of iPhones and iPads) the Tile's are just as good, but can also be used for theft recovery.

 @Mtmw: honest question about how these things work. The tag will be picked up by any IOS device and then those devices will send your phone a signal via cell phone network?
  • 5 0
 @Speeder01: any iOS device will read the tag, send the location at that point in time to the cloud, where your phone retrieves the location for you. Neither phone ever know where or who the other phone is/belongs to.
  • 15 0
 @Speeder01: the Find My architecture is incredibly complex. It is an anonymous, global, peer to peer mesh location API. I’m going to wildly oversimplify here: The AirTag tells any iOS device where it is. That message gets put into an unbreakable envelope and shuffled out into a global mishmash of devices until it gets to your phone, which holds the only key which can break open the envelope. Apple has no idea where the device is and neither does the network.

 Only after 8 to 24hrs at this point in time

 @Speeder01: There are three ways to prevent AirTags from working on an iOS device: 1) opt out of "Find My" network, 2) turn off Bluetooth, 3) turn off Location Services. On my phone, bluetooth is *always* off b/c I hate the technology with a passion, so I'll never be a transmitting or receiving part of Apple's AirTag surveillance racket.

 In principle a neat idea and good solution for … riders running tubeless.

Two problems with having it in the tire:

- Low Psi-setups over rocks or roots seems a menacing risk to the airtag being smashed

In general:

Airtags not being paired with your personal iOS devices notify you that someone elses is travelling with you after about 45 minutes to an hour. Experiencing this with my Airpods Pro from work that i take home with my work-MacBook.

Tire issues - these can happen and you might destroy a couple of Airtags.

Notifications - at least you will have about an hour to see where your bike is headed, in case it hasn’t been discovered.
Or … the thief does not have an iOS device.

Probably the best solution would be if the industry would settle on a technological GPS-tracking and Owner-ID standard, similar to what VanMoof is doing integrated in frames.

 Apple recently introduced an update to the app to alert users to the presences of nearby airtags, due to the numbers of people using them to track/stalk their ex's. This of course means thieves might just go looking for a bike to steal that isn't setting off an air tag alert if they have an iphone and the app.

 An “AirTag Found Moving with You” notification appears when your iPhone or iPad has picked up the same Bluetooth ID as you move from place to place over some unspecified period of time. In addition, one of the following conditions must also be true:

You’ve arrived home, as determined by the address set for the Me card in Contacts.
You’ve arrived at a “significant location,” explained below.
It’s the end of the day (whatever that means), even if you haven’t gone home or to a significant location.

What’s a “significant location?” Your iPhone and iPad track locations that they believe have some relevance to you, whether you’ve visited once or every day for a month.

At a random interval after 8 to 24 hours, the AirTag plays a sound. The sound recurs every so often thereafter.
  • 1 0
 all these are enough for me to figure out where the bike is and hit the thief in a head. The last part takes about 5 min to remove / disable speaker for good so there is no sound whatsoever ( Also 3d printed sleeve reduced sound by like 75% ( just my personal feel)).
  • 2 1
 I don’t see the point of the AirTag for theft prevention as in the U.K. the police still won’t do anything even if you show them the location. They are more likely to arrest you for attempting to recover your own bike than arrest the thief

 Especially with eBikes, there’s just no excuse for manufacturers to not add gps locators to bike frames. Beyond that, there are companies working on the problem. Also, if you look on Facebook marketplace, you will find a low cost option that hides the AirTag in the bottom of the steertube, but as has been pointed out, AirTags aren’t the best solution.
  • 1 0
 Airtags have an OD of 31.9 mm (, so they could fit inside most fork stanchions. Bet someone clever could make a little pocket for one in a 3D printed volume reducer.

Still have the problem of alerting the thief, but I bet most thieves wouldn't think to open up a suspension fork. They'll just destroy the rest of the bike trying to find it, lol.

 Or, you know...I could just put it in the frame. Or paint it black and put it under the seat. After all, I wouldn't be surprised to see it parted out immediately. This is pretty much good for if you forget you wheels places. One hard rock strike is going to destroy this
