I could have hypotheses around wheel dimensions (e.g. width, diameter), materials, etc. that are absolutely great targets for A/B testing.

That sounds like a clear no, you already know the answer to the hypothesized A/B test.

As for the other aspects they sound like great targets for testing within different use-cases, but I'm not sure why that'd be an A/B test as we think of them now.
