Features
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.

Getting started: pairing and personalisation
After securing Cycloop to your bike, download the dedicated app from the Apple App Store or Google Play. The one‑time set‑up is guided step‑by‑step: create your account, scan the QR code on the device, and Cycloop is linked to your phone in seconds. The app will then walk you through calibrating the motion sensors and fine‑tuning the sensitivity to match your riding style and parking environment — whether that is a busy city street or a quiet rural lane. You can also name your bike, upload a photo, and set a primary contact number for alerts.
Once configured, the home screen gives you an at‑a‑glance view of your bike’s status. You’ll see battery level, GPS signal strength, and whether the system is armed. Arming is automatic the moment Cycloop detects that your bike has been stationary for a short period, so you never have to remember to turn it on. If you prefer manual control, a quick tap is all it takes.
How the tamper alert system works
Cycloop uses a combination of accelerometer and gyroscope sensors to detect vibration, tilt, and impact. As soon as someone attempts to move your locked bike, the sensors trigger a two‑stage response. First, the device emits a loud warning beep — enough to startle an opportunistic thief and draw attention. If the movement continues, Cycloop immediately places a phone call to your registered number. Unlike silent push notifications, a ringing phone is far more likely to get your attention, whether you are in a meeting, at home, or asleep.
If you are unable to answer, the app logs the incident and starts recording GPS position updates every few seconds. This live tracking data is stored securely and can be shared with the police or your insurance company. Because Cycloop is hidden on the seat tube and fixed with tamper‑proof screws, a thief cannot simply rip it off. Any attempt to force the device off the frame will generate additional alerts and, in most cases, leave visible damage to the bike — a powerful deterrent.
Precision tracking with built‑in eSIM
At the heart of Cycloop is a multi‑constellation GNSS receiver that uses GPS, GLONASS, Galileo and BeiDou satellites, ensuring an accurate fix even in urban canyons or under tree cover. The pre‑installed eSIM connects automatically to the strongest available mobile network, so you never have to worry about coverage or roaming. Cycloop operates on low‑power NB‑IoT and LTE‑M networks, which are optimised for small, battery‑friendly data transmissions — perfect for tracking devices.
The eSIM is not tied to a single carrier; it roams intelligently across networks, giving Cycloop the best possible signal strength wherever your adventures take you across the UK. There is no separate SIM card to insert, no contract to sign, and no recurring top‑ups. Connectivity is included for the life of the device, so you can set it and forget it.
Maximising battery life and recharging
The built‑in 3.7 V Li‑Polymer battery is designed for endurance. Under normal use — with the lights disabled and the bike parked for most of the day — a single charge can last up to 12 months. When the integrated LED lights are activated (which are automatically triggered by darkness and motion), battery life reduces to around three months if you ride for about two hours daily.
Recharging is simple: a magnetic charging cable clips onto the device without needing to remove it from the frame. A full charge takes approximately two hours. The app will notify you when the battery drops below 20 %, so you have ample warning to top it up. Even at critically low levels, Cycloop enters a power‑saving mode that preserves core tracking functions for several more days.
Designed for the real world
Cycloop carries an IP65 rating, meaning it is completely dust‑tight and protected against low‑pressure water jets from any direction. Whether you are caught in a torrential downpour, splashing through puddles, or cleaning your bike with a hose, the device remains fully operational. The outer casing is made from impact‑resistant, UV‑stabilised polycarbonate, which can withstand knocks, scrapes, and prolonged sun exposure without fading or becoming brittle.
In addition to its robust build, Cycloop has been tested to withstand vibrations from rough trails and the constant jostling of urban cycling. The internal electronics are potted in a shock‑absorbing compound, protecting them from mechanical stress. This durability is what makes Cycloop truly fit‑and‑forget — once installed, it requires no maintenance beyond occasional recharging.
A visible deterrent and a safety light
The LED strip on Cycloop isn’t just for tracking visibility — it actively helps you be seen by motorists, pedestrians, and other cyclists after dark. The lights can be set to steady, slow flash, or quick flash modes via the app, allowing you to adapt to different riding conditions. Because the lights are built into the tracker itself, there are no extra accessories to clip on or batteries to change; Cycloop becomes a seamless part of your bike.
From a security perspective, a glowing light on the seat tube is a clear signal that your bike is protected by active electronics. Thieves tend to bypass bicycles that look well‑defended. Combined with the tamper‑proof mounting, the illuminated Cycloop reinforces the message: this bike is being watched.
Seamless integration with your cycling routine
Cycloop has been designed to fit effortlessly into your daily life. There’s no need to arm or disarm it every time you stop — it knows when you’ve finished a ride and automatically switches to surveillance mode. When you return and start cycling, the sensors recognise the movement pattern of a rider and disarm the alarm, so you never trigger a false alert. The transition is intelligent and transparent.
For families, you can register multiple Cycloop devices under a single account and share access with other household members. Each guardian can receive alerts and track the bike in real time. This makes it ideal for parents who want to keep an eye on their children’s bikes or for couples sharing a pair of bicycles.
