In episode 2 of Fourze, he takes the name of Kamen Rider after seeing footage of Showa Riders. I'm sure Rider 1 was in those clips somewhere. If not, Riders he's had long time team ups with are.

As mentioned, Ghost has Rider 1 cameo in an episode leading into the Rider 1 movie.

Even if you consider the 00's to be alternate universes (which at the time was the easier assumption), the 10's are very well connected to each other and to Showa beyond the movies. It would be silly and needlessly complex to try to explain away these connections without just using the movies.
