RobustWeather resistant and UV protected, extremely strong, durable, made out of polycarbonate and glass fibers. No 3D-print!
Safety screwsTorx-Pin screws hinder unwanted removal of the WOO.
Design & precisionSmall, thin and lightweight: engineered with precision, WOO provides the perfect socket for the Apple AirTag™ to hide inside – no shaking, no rattling.
SustainableEngineered in Germany, produced in Denmark.
In the box
- 1 WOO holder (0.4 oz),
- 2 stainless steel anti-theft screws (25mm length) with key wrench,
- 2 spacer sleeves (optional use for bottle cage),
- Apple AirTag™ optionally available.
Which screw length do I need?We always put two 25mm screws in the box. With that you can mount the WOOs to most frames without hassle – no matter if you are using a bottle cage on top or not. Some E-Bikes only allow short screws which is often stated on the frame. In this case you should choose the variant with additional 16mm screws. The screws are never turned more than 10mm into the whole when mounting the WOO.

AirTags run on Apple’s Find-my-network. They continuously send out Bluetooth codes that are received by Apple devices such as iPhones and reported to the iCloud. Their owners do not notice this and cannot influence it. The codes cannot be traced back to a specific user by third parties. Only the owner of AirTags can check the iCloud to find out where their AirTags are.
Since there are more than a billion Apple devices in circulation around the world, lost (or stolen) AirTags can be easily tracked down. This works especially well in cities, where bikes are typically stolen.
With an iPhone 11 or newer, there is another advantage: Apple’s Precision Finding. This makes it possible to pinpoint the location of an AirTag down to only a few centimeters.
After you unpack the AirTag, you will hear a short sound. This means the AirTag is ready to be connected to your iPhone. When you bring it near your iPhone, you should see the AirTag displayed. You can give it a name and you’re done.
Don’t worry, your iPhone will notify you when it’s time to replace the battery. It’s a coin cell lasts a full year and is easily user replaceable.
AirTags are rated IP67 (maximum depth of 1 meter up to 30 minutes). So you could go for a swim with your bike, but we don’t recommend it. 😉
There are multiple criteria that must be met to let the Anti-Stalking-Mechanism kick in:
- The person must be moving with your bike for several hours.
- The person must be coming home with your bike.
- When coming home the bike must be in close proximity to the person’s iPhone.
If one of them isn’t met, it won’t be turned on. After a few days without connection to your iPhone the AirTag will make a sound when it gets moved.
This should give you enough time to get it back together with the police.
To prevent that, we added security screws which require a special wrench. Of course, this doesn’t make it impossible but harder to remove. Most bike thieves are deciding spontaneously to steal a bike and they have to be very quick.
GPS trackers are a valid option for bike tracking but they have some severe downsides:
- The battery runs out within days or a few weeks, whereas with the battery of the AirTag lasts for one year.
- GPS trackers are heavier and bulkier. Our holder together with the AirTag weighs less than 30g.
- The initial price of a GPS tracker is much higher, usually around 200 Euros. Besides that you have monthly running costs for the mobile contract of a GPS tracker. Also AirTags work worldwide. If somebody takes your bike to Siberia, you’ll find it there.
- Tracking indoors is impossible with a GPS tracker, this is where the AirTag shines. It can even tell you in which floor your bike is located.
No! PLA will degrade over time and change its color. 3D prints are also not very strong. That’s why we are using precision injection molding. The material is a blend of polycarbonate, ABS and glass fibers (depending on the model), which makes it very strong and life proof – perfect for outdoor use and long rides in sunlight.
The spacers are optional, sometimes you have to use them between the bottle cage and the WOO, sometimes you don’t. There are many different bottle cages, some have a convex back which naturally slides into the WOO, pretending it’s a single piece. Others have a flat back (e.g. Fidlock), which then requires the spacers to give it maximum stability. To accomodate both types we put the spacers into the package. Every holder comes with a set of spacers.
