Casey,
The areas that are closed to bikes that we are aware of are the two Wilderness segments: Mt. Rose and Granite Chief Wildernesses. There may have been a few local trails segments, particularly in the Auburn State Recreational Area that were also closed o bikes, but we can’t recall for sure. However, finding ways around the Wilderness Areas might be complicated; we have not attempted to map alternatives. You might consider contacting the Tahoe Mtn. Bike Association via the link in our report for more information about biking options.
regards,
James and Amy
