B'Safe is a real technological revolution for cyclists who are looking for the freedom to ride without worrying about possible future accidents. Ride your bike, you are protected!

How it works

Provided with a powerful algorithm, this airbag vest will protect your daily bike trips! Easy to use and comfortable, it offers an optimal protection of the vital zones of the upper body in case of an accident.

An optimal protection in 4 steps

The system uses a set of on-board sensors that follow the cyclist’s motion in context (more than 1000 times per second). When a fall is detected, the airbag inflates automatically in 80 ms.

Sensor and algorithm

The algorithm:

Our team of engineers recorded thousands of data and simulated hundreds of falls to develop an algorithm capable of distinguishing normal cyclist movements from an accident.

The system consists of 2 sensors:

  • The CDU sensor: situated inside the vest, analyzes the cyclist’s motion in context (GPS, gyroscope and accelerometer).
  • The SDU saddle sensor: placed under the saddle, detects shocks.
    When a shock or abnormal movement is detected, the two sensors communicate with each other and analyze the situation.
    If a fall or accident is detected, the system triggers the airbag to protect the cyclist before impact.

The airbag protection

The vest guarantees optimal protection of three vital areas of the upper body: chest, neck and back. Three areas that can be seriously affected in the event of an accident.

The airbag is made of ultra-resistant nylon that does not tear during inflation.

After each inflation, the airbag deflates automatically and can be reused.
