Skibobbing is winter sport involving a bicycle-type frame attached to skis instead of wheels. Although the original idea for a bicycle with skis was patented as early as 1892, and skibobbing had been a form of transportation in the Alps, it wasn’t until 1954 that the first international race was held.
Czech Republic is very strong in skibobbing. First public competition was held in 1914 in Liberec. The most successful contestant in this sport in history is Irena Francová-Dohnálková who got 29 world championship titles.
