I kind of disagree. I can't comment on Stronger or V3 since I haven't seen them. But Agito was only an ace in terms of his strength. He had little idea of what was going on around him for the majority of the series. Wizard, meanwhile, had the attitude, but he was being played the entire season.
Hibiki, though, yeah. But it makes a lot of sense with him, since he's training the next generation of Oni, not just Asumu and Kiriya, but also mentoring Todoroki from time to time, too. Would be kind of weird for Hibiki to be a blundering teacher :lol

Hibiki is really good at certain things, but has a very pronounced lack of real world skills.

And Tsukasa is a bad photographer :) Yes, and Sento is not that good in everyday things. It is difficult to say about Geats, because we almost never saw him in everyday life.

Well this is a whole new level of crackpot theorising.
(Not exactly sure if this guy's serious or not but I still found it hilarious)

I like it, but when they get to "X" it will be difficult to justify the theory.

I fucking hate the world sometimes.

We will never be free.

Are there any Rider shows where Riders don't use bikes?

Yes, there have been quite a few:-

- Black RX uses multiple bikes, but he also has the car Rideron at his disposal
- Hibiki's riders are often transported via normal cars like Hondas
- Den-O's riders primarily use trains as per the premise of the show
- Aqua from Movie Wars MEGAMAX uses a Jetski
- Drive uses a car and has no bike
- Kamen Rider #3, similarly, uses a car and has no bike
- Kamen Rider #4 uses a plane
- Zi-O's riders primarily use time machines
- Revice uses a hoverbike

Aside from this, there are various auxiliary mechas Riders sometimes use like Kiva's Castle Doran; or other transport like G3's G-Trailer
