Is there a movie site where I can watch The Longest Ride with out a download or signup??

There are several sights where you can watch completely free, such as MEGASHARE.INFO (type movies name and megashare, for example 'cinderella megashare'). There is also putlocker and yify. :) There is also Xmovies8. :)
Also, since the movie is quite new, you might want to consider waiting a while before searching again. :)
Hope that helps!
