e-CAL 1020

/2017

The Punkt. Urban Mobility Project is an educational collaboration between Punkt. and three leading design schools: ECAL (Lausanne), RCA (London) and Design Academy (Eindhoven). The brief: create a personal transportation product that innovates in both style and function, specific to the needs and opportunities found in the cities where the students are studying.

Traveling in Lausanne means short distances but steep hills. This retro-fit motor harvests downhill braking energy that would otherwise be wasted as heat, and stores it ready to send back to the wheel the moment it is needed.

Under the guidance of Thilo Alex Brunner, Head of th programme, ECAL Master Product Design students created e-CAL 1020, a plug and play electrical engine which transforms your bicycle into an e-bike. It is solely recharged by human effort using a generator similar to KERS (Kinetic Energy Recovery System), a technology used in Formula 1.
