There is nothing worse than getting a skibike only to find out that the mountain you want to ride at does not allow them.  Don’t assume that a particular mountain is skibike friendly just because you saw a bike there.  A lot of mountains are NOT skibike friendly, but may allow bikes to people with disabilities through their adaptive program.   There is a full list of skibike friendly mountain found on the American Skibike Association’s page Where To Ride.
