Assuming another no snow winter...
You'll be a half hour from Nyack area, which has good documented rides north and south, and east is interesting because you cross the new bridge into Westchester County. On that side of the Hudson, the South County section of the Empire State Trailway is about a mile away and heads to Brewster and north.
South from Nyack there's the classic loop on 9W toward the George Washington Br and up River Road.
Empire State Trailway, Maywood trail.
