Pretty good sound description; thank you very much 
Please jump here and listen; it’s the same noise, correct?
If yes - we have here another classical creaking noise issue…
(And you don’t need oil/lube below the cup spring 367, you need anti seizing compound.)
Sideway movement of the rear wheel
Strida 5.0 “clicking” noise
crackling noise repair kit instructions
I’d say that’s common, many Strida’s are doing that.
(Just checked at an EVO and wondered that it did not…)
Sorry, but I can’t verify that - would you please tell me where you found this?
And I’m afraid I don’t understand your last question…could you try different words?
