The project focuses on renewable energy.
The rigid cover is composed of a battery and a plug powered by a dynamo driven by the front wheel and a solar panel.
The goal is to recharge a smartphone slipped into the rigid cover and multiply the sound of the phone when this one's ringing for the user to hear when he's rolling bicycle.
The rigid cover is protected by a shell shocked carbon containing LEDs to be seen from front and back. That is contoured to reduce windage.

Finally, the system is attached to the left bicycle's fork because in France we drive on the right of the road pavement (like a lot of country).
