I'm a snowmobiler in addition to bikes and I've watched for a good bike track to come along. The RADIX looks like it takes on the powder the best, and is very impressive climbing, in the videos. Still nothing as floatable as the regular snowmobile for climbing in powder. Shifting would suck, but those bikes look to be as smooth if not smoother riding than a traditional sled ,,, thus very viable for trails and Spring (heavy packed snow) conditions. A bike with E-start would sure be nice for this application.
