Behind the Scenes: How Stationary Bicycles Lit Up the Night in Switzerland

On Rare Disease Day, CSL brought together a team of volunteers who pedaled during daylight hours to generate energy needed for a nighttime light display in Bern.


A sign of support for millions of rare disease patients took more than a flip of a switch in Bern, Switzerland.

To model responsible use of energy, on February 29 participants took 30-minute slots on bikes connected to a generator at Burgerspital Bern, former hospital, built in the 1700s. Cyclists – in shifts from 9 a.m. to 6 p.m. – included CSL employees, members of the Bern Ice Hockey team and the BSC Young Boys football club.

The power they banked was used to create a colorful light display on the building’s east façade that was part of the Global Chain of Lights on Rare Disease Day. Watch the video above to see how their hard work paid off.
