Summary of the technology

Regenerative braking device capable of storing the kinetic energy absorbed during the braking process of the bicycle, by compressing ambient air and storing that energy as compressed air. This compressed air is used as an energy source in case of need extra help in cyclist’s pedalling.


New and innovative aspects

The main novelty is the accumulation of kinetic power through a pneumatic regenerative braking system instead of an electrical one, as usually occurs in mainly all the similar technologies nowadays.

It uses simpler and cheaper elements, fact that decreases manufacturing and maintenance costs.

Main advantages of its use

  • Possibility to be joined, as a "kit" to any bike model, from mountain bikes to city ones (the set of mechanisms associated with this process are inside the rear wheel).
  • Facilitates displacement going uphill sections or high effort through the consumption of the stored energy.


Bicycle with the purpose of use the energy lost in braking process to dispose of it when necessary, similar to KERS cars racing applied to cycling. This converts the kinetic energy of the user and his bike in pressure by compressing atmospheric air to an engine / rotary vane pump and stores it in a tank of carbon fibre.

When user needs extra power, turns the accelerator and the system delivers the energy stored in the reservoir to the compressor, so it does motor functions.

This device includes an electro-hydro- pneumatic control system that implements the regenerative brake, non-regenerative brake and accelerator functions.


Users who want simultaneous access to a conventional or impulse bicycle according to the effort requested in each section of the journey.

Users with special needs for moving.
