When the words "taken to" are followed by a gerund, such as "wearing", it means that they have started to do that thing with regularity, like a new habit.

Thank you, Tatyana! I'm an English beginner here. I think you asked a very meaningful question. I want to know that interesting thing, too. I hope more answers here. 

Thank you, Jessa! You let me know more.

in "Simone's TAKEN to wearing a helmet whenever she goes cycling." maybe thgere was something that made Simone to want to wear a helmet.

Means "has started to want to wear a helmet".
