In the snowy areas of the country, the fat bike has made a way for us to keep riding and not hang up the wheels for the winter. If you are gravity-addicted, then a ski bike might make a better ride for your winter. This is nothing new, as Lenz Sport has been converting their summer bikes for a long time, and even has a ski-specific model.
If you are lucky enough to be in Germany or Austria during the winter, Sledgehammer is promoting their new ski bikes by renting them for €30 per day, including shipping them to you, and shipping them back at the end of the rental. They hope this access will make people interested in giving them a try.
The video is a pretty good explanation of what happens with a ski bike, and is great to watch, especially if you like watching people crash as they attempt to try a backflip.
