"הוא יכול לראות את האופניים האלו?"

Translation: Can he see that bicycle?

[saracen93]

I know this kind of like the English word "sunglasses" where it's considered a plural, thus they used האלו. But can this also mean plural bikes? Because I got the answer wrong when I typed "these bicycles."

[AlmogL]

You're right, it should be accepted.

So what is the difference between one bycicle and many bycicles?

[IngeborgHa14]

I think, if you have more than one bike, you would speak of זוּגוֹת אוֹפַנַּ֫יִם ("pairs of bicycles").
