The 500 cyclometer has been developed by our engineers for cyclists looking for a simple wireless cyclometer to reliably measure their performance.
Discreet and very easy to install (magnet-free sensor that mounts on the wheel hub): 8 basic functions with wireless transmission at up to 3 metres, allowing mounting on the rear wheel.
The 500 cyclometer has been developed by our engineers for cyclists looking for a simple wireless cyclometer to reliably measure their performance.
Digital clock (12/24 hours) Trip time (hh:mm:ss) Current speed (instant speed) Average speed Maximum speed Trip distance Total distance (odometer)
Temperature CO₂ reduction indicator Low-intensity backlight (to illuminate the screen for night use)Auto pause mode .
An innovative sensor that fits on the wheel hub and detects speed using a magnet-free gyroscope. It's therefore really easy, fast and reliable to install. 2.4 GHz digital transmission. No interference possible. Communicates with the cyclometer over up to 3 metres. You can therefore mount it on the rear wheel and use it with a turbo trainer.NOTICE: This technology is not compatible with rough terrain and may display speed incorrectly.
Thanks to its sensor which is fitted directly on the wheel hub, this cyclometer is perfect for non-connected home trainers. It will show the distance you travelled as well as your speed. Perfect for winter indoor training sessions!
CR2032 (1 in the cyclometer + 1 in the sensor).The sensor is always active when it detects movement, whether or not it's connected to the cyclometer. If you're going on rides but don't need it, we recommend removing it to conserve your battery.
Case: Height x width x depth: 70.3 x 44.5 mm x 16.2 mm Wheel hub: First silicone band size:Hub diameter 24 mm ~ 32 mm, maximum diameter = 34 mm Second silicone band size:hub diameter 19 mm ~ 23 mm, maximum diameter = 25 mm
CR2032 (1 in the cyclometer + 1 in the sensor).The sensor is always active when it detects movement, whether or not it's connected to the cyclometer. If you're riding but don't need it, we recommend you remove it to save energy.

Discreet and very easy to install (magnet-free sensor that mounts on the wheel hub): 8 basic functions with wireless transmission at up to 3 metres, allowing mounting on the rear wheel.

Current/average/max speed, total/ride distance, time, stopwatch, temperature.

3 easily accessible buttons. Very simple, intuitive menus.

Watertight assembly, durable case.

You can install your sensor on the back wheel for using a turbo trainer.

Large figures and back-lit display to make it easy to see, even at night.

Easy to fit. Magnet-free sensor mounts on your wheel's hub.
