Is the word ciclistas the same in Brazilian and European Portuguese?

Yes

The difference between "ciclistas" in Brazilian Portuguese and Continental Portuguese is purely related to pronunciation. There are no differences in meaning, spelling, or grammatical function.

In Brazilian Portuguese, the "s" at the end of the word is generally pronounced as a soft "s" (like the "s" in "sun"). In Continental Portuguese, the "s" at the end of a syllable or word is typically pronounced as "sh" (like the "sh" in "shoe"). Additionally, speakers in Portugal tend to reduce unstressed vowels more significantly than Brazilians, making the word sound slightly more "clipped."
