thank you for the great number of answers, I did not think to open such a debate, your knowledge is big, but unfortunately my english is not so smart, I use google translator to help me to understand, but often the translator doesn't understand, is it a good bike or is it not?
I post another photo, please consider that I could have the bike for 150 € I was under illusion that it could be a good bike to have and to work on, maybe not.
Thank you again, and hope to write you soon for other good advices
