Designed for Every Rider’s Peace of Mind
Whether you commute daily through busy city streets or enjoy weekend adventures on rural trails, knowing your bicycle is protected gives you the freedom to focus on the ride. Cycloop’s discreet design blends into your bike’s frame, so it doesn’t attract unwanted attention, yet it remains always on guard. Its advanced motion sensors can distinguish between a gust of wind knocking your bike and an actual theft attempt, reducing false alarms and ensuring you’re only alerted when it truly matters.
Unlike bulky GPS trackers that are obvious and easily disabled, Cycloop is engineered to stay hidden. The tamper-detection system immediately notifies your phone if anyone tries to forcibly remove it. Because the unit is bolted securely and requires a special tool to detach, thieves cannot simply snap it off. In the event of a theft, real-time location tracking provides accurate coordinates, helping law enforcement recover your bike faster.
Key Fob Technology: Hands-Free Protection
The included Key Fob is the heart of Cycloop’s effortless user experience. Keep it on your keychain or in your pocket, and as you approach your bike, the system recognises the fob’s unique encrypted signal and disarms automatically. No pressing buttons, no app to open – just unlock your bike and go. When you walk away, the absence of the signal arms Cycloop, creating an invisible shield around your bicycle.
The fob uses long-life battery (included) and has a range optimised for reliable detection without interfering with neighbours’ property. You can pair multiple fobs with one Cycloop, which is perfect for families sharing a bike. The encrypted communication prevents relay attacks and signal cloning, so only your fob can disarm the tracker.
Install Like a Pro: Tips for a Perfect Fit
Mounting Cycloop on your seat tube is straightforward, but a few tricks ensure the best performance. First, choose a location where the tracker sits flush against the frame and is shielded from direct knocks. The two included sizing rubbers help adapt to tube diameters between 25 mm and 37 mm; select the thicker insert for narrower tubes for a tighter grip. Before fully tightening the four screws, check that the tracker does not obstruct your pedalling or interfere with any bottle cages. Once mounted, give it a firm shake to confirm it’s rock solid.
Next, download the Cyclooptracker app and follow the pairing wizard. The eSIM inside Cycloop activates automatically during setup, so you won’t need to insert a physical SIM card. After a successful pair, test the system: arm the tracker, take the key fob out of range, then gently move the bike. You should receive a test alert. That’s it – your bike is now connected.
Stay Connected with Built-in eSIM
Cycloop comes with a pre-installed eSIM that works across the UK and over 150 countries, so whether you’re touring in Scotland or cycling through Europe, your bike’s location updates continue seamlessly. The first two months of service are on us; after that, the subscription is just £36 per year, giving you unlimited tracking and alerts. You can manage your subscription, pause it, or update payment details directly in the Cyclooptracker app.
Because the eSIM is integrated, there’s no need to juggle separate SIM contracts or worry about physical cards being removed. The network automatically selects the strongest signal from multiple carriers, maximising reliability even in weak coverage areas. All cellular data is encrypted end-to-end, safeguarding your location information.
Long-Lasting Battery and Proactive Alerts
Cycloop’s battery is designed to last up to 12 months on a single set of batteries under normal use. When the power runs low – typically well in advance – the Cyclooptracker app will push a notification to remind you. Replacing the batteries takes only a minute: unscrew the weatherproof cap, swap in two fresh AA lithium batteries (recommended for best performance in cold climates), and screw the cap back on. The tracker will retain all its settings, so there’s no need to re-pair.
The app also keeps you informed of the tracker’s health. If the signal is weak or the device hasn’t checked in for a while, you’ll know right away. This proactive monitoring means you’re never left wondering whether your protection is active. It’s just another layer of confidence Cycloop provides.
Smarter Than a Padlock: Integrated Security for Modern Threats
Traditional U-locks and chains only delay a determined thief with the right tools. Cycloop complements your physical locks by adding real-time location tracking. If a thief cuts your lock and rides away, you receive an immediate phone call. You can then open the app to see the bike’s movement on a map, share the live location with the police, and dramatically increase the chance of recovery – often within hours.
Many Cycloop users report that the visible presence of a tracker acts as a powerful deterrent. Even though the device is discreet, the knowledge that a GPS tracker might be fitted changes a thief’s risk calculation. Combined with a good-quality lock, you’re building a layered defence that makes your bike a much less attractive target.
Tailored for the British Cycling Lifestyle
From the cobbled streets of Edinburgh to the coastal paths of Cornwall, British cyclists face diverse weather conditions. Cycloop’s casing is IP67-rated, meaning it’s fully protected against dust and can withstand immersion in water up to 1 metre for 30 minutes. Rain, mud, or even a splash through a ford won’t faze it. The internal electronics are sealed against moisture, and the external metal components are corrosion-resistant.
We understand that cycling is a year-round passion in the UK. That’s why Cycloop is tested to operate in temperatures from -20°C to +60°C. Whether it’s a frosty winter commute or a hot summer ride, the tracker stays reliably on guard. Mounted under the seat or on the seat tube, it benefits from some shelter while remaining fully functional.
