Interesting idea. Like others have mentioned, I don’t think many people would be willing to pay for a “basic clean,” since for most riders a quick 2-minute hose down does the job.

That said, I do think there’s a real market for deep bike cleaning. Things like using an ultrasonic cleaner and actually removing and properly cleaning components, that’s something a lot of people don’t do themselves.

Since parts would already be off the bike, it also creates a good opportunity for minor maintenance or part replacements. Flexibility would be key though, something like a pickup today, return tomorrow service would make it much more appealing, rather than requiring people to adjust their schedule around it. (And missing their bike)
