202 years ago Mounta Tambora erupted, having an effect on the global weather. The famine that followed led to people having to eat their cattle and horses, meaning they no longer had animals to draw carriages and plows. In response to this need (to enable people to use an alternative mode of transportation) the German inventor Karl Drais developed the world’s first bicycle. 12 June marks the day he undertook the world’s first bicycle ride, 200 years ago. To celebrate this occasion the Geological Survey of Norway (NGU) encourages you and challenges you to grab that bike and ride 8km on 12 June! Have a look at the flyer for more information. So have fun and start cycling!
