MADISON, Wis. (AP) -- The Wisconsin Department of Natural Resources is warning cycling enthusiasts that so-called "fat" bikes may not be allowed on snowmobile trails.
Fat bikes have wide, low-pressure tires designed for pedaling on snow and sand. Cyclists can use them on DNR state trails that allow biking at other times of the year unless that trial is open for cross-country skiing.
But DNR officials says most of the state's snowmobile trail system runs through county, federal or private land that may prohibit bicycle use. The agency says winter cyclists should check their favorite trail's regulations before heading out.
Brigit Brown is the DNR state trails coordinator. She says fat bike cyclists operating legally on snowmobile trials should still watch out for snowmobiles that might be traveling at high speeds.
