Frequently Asked Questions

Most trackers announce themselves. A bright plastic tag on your bike tells a thief exactly what to remove first.

MIMBO hides the tracking inside things you already carry. The Tracking Bell looks and rings like an ordinary bicycle bell. The Tracking Card is the thickness of a credit card and disappears into a wallet slot. You get the location, without the giveaway.

Each MIMBO tracker sends out a short, encrypted Bluetooth signal. Any nearby smartphone running the matching network picks that signal up and privately relays the location back to you — the owner of that phone sees nothing and is never told.

The Tracking Bell uses Apple’s Find My network, which runs on the iPhones and iPads around it. The Tracking Card uses Android’s Find Hub network, which runs on nearby Android phones. Both networks are already built into hundreds of millions of phones, which is why there is no subscription to pay.

No, and the difference matters — so here it is plainly.

A GPS tracker carries its own satellite chip and SIM card, reports its own position anywhere on earth, and needs a monthly data plan to do it. MIMBO uses Bluetooth and the Find My / Find Hub networks instead. Its location updates when a compatible phone passes close enough to hear it.

What that means in practice: in a city, a campus, a train station or any busy street, updates arrive often because phones are everywhere. On an empty rural road or inside a sealed metal container, there may be no phone nearby and the location will show where it was last seen.

The trade-off is deliberate: no SIM, no monthly fee, and a battery measured in months rather than days.

Start with your phone, then your item.

• iPhone, and you want to protect a bike — the Tracking Bell. It mounts to your handlebars, works as a real bell, and runs on Apple Find My.
• Android phone, or you want to protect a wallet, bag, passport or luggage — the Tracking Card. It is 1.8 mm thin and runs on Android Find Hub.

They are not interchangeable, because Apple and Google run separate networks. Pick the one that matches the phone in your pocket.

The Tracking Bell. It pairs directly with the Find My app that is already on your iPhone — nothing to download, no account to create.

The Tracking Card is built for Android’s Find Hub network and will not appear in Apple Find My.

The Tracking Card. It pairs with Find Hub, which is already on Android phones from Samsung, Google Pixel, Motorola and most other major brands. Keep Google Play services and Find Hub up to date for the best results.

The Tracking Bell runs on Apple Find My and will not pair with an Android phone.

No. Apple’s Find My and Android’s Find Hub are two separate networks, and each MIMBO tracker is built for one of them.

If your household runs both, that is fine — the Bell can be paired to the iPhone and the Card to the Android phone. They simply live in different apps.

It fits handlebars from 22 mm to 31.8 mm, which covers the large majority of city bikes, road bikes, hybrids, e-bikes and many scooters. Mounting adapters are included in the box, so you do not need to buy anything extra.

Measure the flat section of your handlebar next to the grip if you are unsure.

Yes. It rings like any other bicycle bell — that is the whole point. Nothing about it reads as a tracker, so there is no reason for anyone to pull it off.

Both products are rated IP67: sealed against dust and able to survive being submerged in up to one metre of water for 30 minutes.

In everyday terms, rain, road spray, puddles, snow and a wallet that went through the wash are all fine.

85.6 × 54 × 1.8 mm — the footprint of a bank card and roughly the same thickness. It sits in a card slot you already use without making your wallet bulge.

A polycarbonate and ABS housing with a copper dome for the ring. It measures 80 × 100 × 50 mm and weighs 100 g, so it adds no meaningful weight to the bike.

Under a minute, on the iPhone you already have:

1. Mount the bell to your handlebars using the included adapter.
2. Open the Find My app and go to the Items tab.
3. Tap Add Item, then Other Supported Item.
4. Hold your iPhone near the bell and follow the prompts.

No app to download, no account to create.

Equally quick, on your Android phone:

1. Open Find Hub.
2. Choose to add a new device or tracker.
3. Hold the card near your phone and follow the prompts.
4. Slide it into your wallet, bag or luggage.

No cable, no extra app, no account to create.

Yes. Add as many MIMBO trackers as you like — a bell on each bike in the family, a card in a wallet and another in a suitcase. Each one appears separately in Find My or Find Hub, and you can rename them so you know which is which at a glance.

Yes, and it is the feature you will use most. If the tracker is within Bluetooth range, open the app and choose Play Sound. That is what actually finds a wallet under a car seat or a bag behind a sofa.

Yes. Both Apple Find My and Android Find Hub are worldwide networks, so your tracker keeps reporting wherever compatible phones are around — which is most populated places on earth.

You do not need to change a setting, buy a local SIM or pay a roaming charge.

No. It runs on a standard CR2032 coin cell that lasts 6–8 months depending on use. When it runs down, swap in a new one — they cost a couple of euros and are sold in every supermarket and hardware shop.

No cable, no charging night, no dead tracker because you forgot.

Wirelessly. Set it on any Qi wireless charging pad — the same one you use for your phone works. A full charge lasts around 3 months.

For the most reliable result, place the card on its own rather than stacking other cards or metal objects on top of it.

Your phone tells you. Both Find My and Find Hub show a low-battery indicator next to the tracker, so you get warning well before it stops reporting.

No. Find My is already on every iPhone and Find Hub is already on supported Android phones. There is no MIMBO app, no login and no account to create — which also means there is no extra company holding your location data.

Yes. Both networks are built around end-to-end encryption. The phones that help relay your tracker’s position cannot see what they are helping find, and their owners are never notified. Only you, signed in to your own Apple or Google account, can see where your item is.

MIMBO never receives your location at any point.

The Tracking Bell is built on an Apple-certified Find My module, which is what allows it to appear natively in the Find My app alongside Apple’s own products. That certification is held by the module manufacturer.

MIMBO is an independent brand and is not affiliated with, endorsed by or sponsored by Apple Inc. or Google LLC. Apple, Find My and iPhone are trademarks of Apple Inc.; Android and Find Hub are trademarks of Google LLC.

Yes. Because MIMBO plugs into Apple’s and Google’s own tracking frameworks rather than a separate app, it keeps working through iOS and Android updates without anything for you to reinstall.

None. You pay once. There is no subscription, no activation fee and no data plan, because MIMBO uses the Find My and Find Hub networks that are already running on the phones around you.

Yes, and they are where the value sits. Buy 2, get 1 free and buy 3, get 2 free are applied automatically at checkout — no code to enter.

Most people who buy more than one do it for a second bike, a partner’s bike, or to put a card in both a wallet and a suitcase.

The product should come back in its original condition and packaging, and you will need your proof of purchase.

Email support@getmimbo.com with your order number and a photo of the problem. We will send a replacement or refund you — you will not be asked to argue for it.

Every MIMBO product carries a 12-month warranty against manufacturing defects, running from the day it is delivered. If something fails because of faulty materials or workmanship, we replace it.

The warranty does not cover theft, loss, accidental damage or normal battery wear. Your statutory rights in your own country apply on top of this.

An honest answer, because it matters more than a reassuring one.

MIMBO substantially improves your chances — most bikes are taken in populated places, and a tracker that a thief has no reason to remove keeps reporting. But no Bluetooth tracker can promise recovery. If a bike is stripped, taken somewhere with no phones nearby, or shielded inside metal, the location will stop updating.

If it happens: report the theft to the police and give them the location history from your app. Do not go and confront anyone yourself — a bike is replaceable and you are not. MIMBO is a tool to help the police act, not a reason to take a risk.
