Snow biking is the newest hit in the USA and starts to pick up here in Europe, too.
Everyone who is used to ride an ordinary bike has no problem to learn snow biking in one morning. To know the run is not necessary. After a 3 hours crash course you should be able to glide, carve, drift, taking short curves and of course the ski lift is no problem either. O yes and after lunch you already are terribly addicted to this sport.
