Easy to install Mount the Cycloop on the seat tube of your bike - only 4x screws to install it in place, with screws and a special key included in the package. The anti-theft system comes with batteries already installed, so you can start using it right away.
Simple setup The Cycloop anti-theft system will pair with your phone via a mobile app. On first use, the app will guide you through a simple setup wizard. You will also be able to fine-tune device sensitivity. Cycloop comes with an eSIM pre-installed for seamless connectivity.
Deters thieves Installed on the seat tube of your bike, Cycloop acts as an effective thief deterrent. The GPS anti-theft tracker will alert you as soon as it is tampered with. Cycloop uses specially designed screwheads - it is highly unlikely the device can be removed without specialist tools or damage to the bike itself, making your bike an unattractive target to thieves.

Damage resistant Cycloop is resistant to blows, cuts and other physical damage. Unlike bike locks, it is highly unlikely the device could be removed ‘in the act’. The anti-theft system will alert you as soon as it detects any tampering - way before there is any reasonable chance to remove it from your bike.
Long battery life Cycloop comes with a 3.7V Li-Polymer rechargeable battery, with enough ‘juice’ to power the device for 12 months (without the use of external LED lights). With the lights on, Cycloop will need to be recharged only once in 3 months (with 2 hour daily usage).
Calls your phone A phone call is worth more than 100 notifications - at least in getting someone's attention. Cycloop calls your phone in less than a minute when suspicious movement or device tampering is detected. It helps you to notify the authorities or react instantly to stop your bicycle theft in its tracks.

Maintenance free Install, secure and forget. With batteries enough to power your device for 12+ months (you will be alerted via the app in case their level gets low), there is no tracker maintenance required.
Water resistant Well, of course, Cycloop is water resistant and weather-proof. Rain or shine, road or trail, Cycloop will humbly serve you wherever your adventure will take you.
Ergonomic design Cycloop combines style and security into an easy-to-install package. It bonds with your bike frame and is the best looking bicycle anti-theft device. Period. In addition to looks, Cycloop is designed to withstand damage, mounts securely on your bike and is IP65 rated.

Improved visibility It’s not only about the bike’s security. It’s also about you. Cycloop doubles as a lighting accessory at night, making you more visible to the surrounding traffic. The lights may be disabled for improved battery life.

How Cycloop Works
Cycloop is more than just a GPS tracker; it's a comprehensive anti-theft system that leverages multiple technologies to keep your bicycle safe. At its core is a high-sensitivity motion sensor integrated with a GNSS receiver (GPS, GLONASS, Galileo) that pinpoints your bike's location within meters. This is combined with a built-in eSIM that provides cellular connectivity across multiple networks, ensuring reliable communication even when your bike is stolen and moved far away.
When you arm Cycloop via the companion app, it enters a low-power monitoring state. The moment it detects unauthorized movement—whether someone is trying to cut the mount, lift the bike, or ride away—it immediately wakes up and sends an alert. Within 30 seconds, your smartphone receives a push notification, and if the tampering continues, Cycloop will actually call your phone. This direct call cuts through the noise of standard notifications, ensuring you don't miss the critical alert.
Location tracking is updated in real-time during an alert, allowing you to follow your bike's movement on a map. The system also logs historical location data, so even if the bike is moved to an area with poor reception, the last known position is preserved. All this happens automatically, with no manual intervention needed once set up.
The Anti-Theft System in Action
Imagine you're inside a cafe, and your bike is locked outside. A thief approaches, cutting the lock. As soon as they disturb the bike, Cycloop's motion sensor triggers. You get a notification on your phone. If they attempt to remove the Cycloop device itself, its tamper-resistant screwheads and internal shock sensor send another alert, and the device starts calling you. You can then call the police while tracking the bike's exact location.
Because Cycloop is mounted securely on the seat tube and looks like a sleek accessory, thieves often overlook it. They might not realize the bike is being tracked until it's too late. The loud call alert also acts as a psychological deterrent—some thieves abandon the bike once they realize they're detected.
The system is designed to minimize false alarms. Sensitivity settings in the app let you calibrate what constitutes a threat, reducing alerts from wind or minor bumps. You can also set geofence zones around your home, workplace, or favorite parking spots, receiving instant alerts if the bike leaves those safe areas.
Installation and Compatibility
Cycloop is engineered to fit a wide range of bicycle frames. The standard mount accommodates seat tubes with a diameter from 27.2 mm to 34.9 mm, covering most road, mountain, hybrid, and e-bikes. Adapters are available for non-round tubes or smaller diameters, ensuring a snug, rattle-free fit. The four-screw mounting system uses a proprietary key, so once installed, the device cannot be removed without that key and considerable effort.
The installation process is straightforward and can be completed in under 15 minutes. You don't need to drill or modify your frame—the mount clamps securely and does not damage the paint. The kit includes all necessary hardware and a detailed quick-start guide. For visual learners, the app provides step-by-step video instructions.
Cycloop is designed to be unobtrusive. When mounted, it sits flush along the seat tube and integrates with the bike's lines. It's available in multiple color options to match common frame colors, making it even less noticeable. For those who want extra security, the device can be installed upside-down or in alternative positions following our guidelines to confuse thieves.
- Fits seat tubes 27.2–34.9 mm (standard clamp)

Battery and Charging in Detail
The integrated 3.7V Li-Polymer battery is chosen for its energy density and long cycle life. Under normal use (motion sensor active but no lights), a single charge lasts up to 12 months. With the LED safety lights active for approximately 2 hours daily, expect around 3 months between charges. The app displays the exact battery percentage and estimates remaining days based on your usage pattern.
Charging is done via a magnetic USB cable that attaches to a sealed port on the device, maintaining the IP65 water resistance. A full charge takes about 2.5 hours. The magnetic connector ensures no wear on physical ports and protects against moisture and dirt. An LED indicator on the device glows green when charged, orange when low, and red when critical.
To conserve battery, Cycloop enters ultra-low-power mode when your bike is stationary and the device is armed. It wakes periodically to check for movement or network signals. This intelligent power management is what makes the year-long battery life possible. You'll receive a push notification well before the battery runs out, giving you plenty of time to recharge.
App and Connectivity
The Cycloop mobile app, available for iOS and Android, serves as the command center for your anti-theft system. Beyond arming and disarming, you can adjust motion sensitivity, set geofence zones, view location history, and manage multiple Cycloop devices. The interface is intuitive, with a clean design that prioritizes critical alerts.
The eSIM inside Cycloop connects automatically to the best available cellular network, with coverage in over 150 countries. There's no need to sign up for a separate data plan; the connectivity is included and managed by Cycloop. The device maintains a low-bandwidth connection to our secure cloud servers, transmitting encrypted location data and receiving commands instantly.
Firmware updates are delivered over-the-air, so your Cycloop gets smarter over time without any effort. The app also provides a community feature (opt-in) where you can receive alerts about theft hotspots in your area. Privacy is paramount: location data is only shared when you activate tracking mode or an alert is triggered, and you can delete your data at any time.
