This is a topic in which you can (and should) talk about bicycles. After all, we love them!
You can tell about your bikes and show their photos.
You can talk about how you want to improve them. Or have already improved. And of course - about the bike of your dreams.
You can talk about your pleasant walks, and maybe about traveling by bike.
In general, everything related to the bike.
I hope that the communication will be pleasant.
P.S. Knowledge of other languages other than Russian, to be honest, is practically absent from me. I use online translators. So if something is unclear in my messages, please do not hesitate to tell me about it. And I will try to formulate my phrases a little differently without losing meaning.
