Measure, anticipate, ride calmly.
Looking Behind
The bicycle radar, mounted under the saddle, like the Bryton Gardia, detects vehicles approaching from behind, up to several dozen metres away, and alerts you via the GPS display or an audible signal. It features a rear light that increases in intensity as a car approaches. On country roads, it provides valuable awareness, without replacing a glance over the shoulder.

Bicycle electronics also include:
- GPS.
- Home Trainer.
- Lights.
- Smartwatches and Fitness Bands.
- Smartphones and Accessories.
- Drones and Cameras.
- Batteries.
All the electronics are gathered on the electronics page.
Measuring Power
The power sensor measures the actual effort produced in watts, making it the reference for precise training. It is located in the pedal, like the Favero Assioma, in the crankset, like the Sram Red AXS, or in the spider, like the Sigeyi AXO. A sensor on one leg estimates the total power; a sensor on both legs, like the double version of the Assioma, also measures left-right balance.
Cadence and Safety
The cadence sensor Garmin, mounted on the crank, measures the pedalling frequency, useful for improving your speed. The fall detector Tocsen, attached to the helmet, triggers an alert to contacts and the user community in case of a shock with no reaction from the cyclist. These sensors connect via Bluetooth or ANT+ to the computer and smartphone.

Frequently Asked Questions
How does a bicycle rear radar work?
Mounted under the saddle, the radar, like the Bryton Gardia, detects vehicles approaching from behind and alerts you via the GPS display or an audible signal. It does not replace a glance over the shoulder.
Pedal power sensor or crankset sensor: which one to choose?
Power sensors in pedals, like the Favero Assioma, can easily be transferred from one bike to another. The sensor integrated into the crankset, like the Sram Red AXS, is discreet and protected, but it is tied to a single bike.
Is one pedal sensor enough to measure power?
A pedal sensor measures one leg and doubles the value, which is sufficient for most cyclists. Two pedals measure each leg and reveal any imbalance; the Favero kit allows switching between the two.
What is the purpose of a cadence sensor?
The cadence sensor, like the one from Garmin, measures the number of pedal turns per minute. It helps find an effective cadence, work on speed, and better manage effort.
How does a fall detector for cyclists work?
The Tocsen detector, attached to the helmet, detects the typical impacts of a fall and triggers an alert via smartphone to notify contacts or nearby cyclists.
