What's a cross-byke?

mountain-byke

Well, something similar : here you will find full explanation

Thanks, but the link you sent says it's called a "cyclo-cross bike". I never saw bike spelled with a "y" anywhere.

The "y" was a mistake, of course. Sorry! I'm going to search again on the web about the cross-bike.
Done. A lot of sites with cross-bikes! It is spelled also- 'cross bike - with ' before (for the missing "cyclo", I suppose).
The same thing is called also dirt bike and dirty byke.

I think the ' is for the missing "moto" - "motocross" is the original word, isn't it?

"Dirt bike" is a familiar term to me - not "dirty byke" - why the "y" again???

oooops..I don't know why, it comes automatic to me...(the "y".
In Italian "bici" is short for "bicicletta"; it never can be "motorbike". Motocross is something you do with a cross motorbike; cyclo-cross you do with a cross bike (two wheels and no kind of engine).

Thanks for the clarification. Anyway, I've edited it to "cross bike" - no "y" and no hyphen - and accepted it.
