No one can criticize you if you keep it simple*:

Cinelli |bike|
Pinarello |bike|
Colnago |bike|
Ciocc |bike|
Battaglin |bike|
Bottecchia |bike|
d'Croce |bike|
Guerciotti |bike|
Bianchi |bike|
Motobecane |bike|
Gitane |bike|

Examples:
How much is that "bike" over there?
That's a really nice "bike".
Hey, I have that same "bike"!

*Note that in some circles, "Schwinn" is synonymous with "bike" - So don't be too surprised if that Pogliaghi is listed on CL as a "Schwinn".
