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

Yes

The word "bicicleta" is identical in spelling, meaning, and grammatical function in both Brazilian and Continental Portuguese. The only difference is pronunciation:

• Brazilian Portuguese: The vowels are more open and clearly articulated. The "i" and the unstressed "e" are pronounced distinctly.
• Continental Portuguese: The vowels are more closed and often reduced. The unstressed syllables are "swallowed" or shortened, making the word sound more clipped and less melodic than in Brazil.

Brazilian Portuguese examples:

1. Eu comprei uma bicicleta nova. (I bought a new bicycle.)
2. Você quer ir de bike para o parque? (Do you want to go by bike to the park?)
3. A minha bicicleta está com o pneu furado. (My bicycle has a flat tire.)
4. Ele usa a bicicleta para trabalhar todos os dias. (He uses the bicycle to work every day.)
5. Você gosta de andar de bicicleta no fim de semana? (Do you like riding a bicycle on the weekend?)
