Thierry Dumaine's Miss Courant D’air is a concept bike that is quite different from any other electric bike. The bike is capable of generating renewable energy as it moves. The bike consists of three large fans that are connected to a generator. When the bike moves, the wind turns the fans and produce electricity.

Miss Courant D’air is fitted with a battery that stores the energy which can be utilized to power a small in-wheel electric motor, making it super energy-efficient.
