Unless the OP is under a medical restriction not to lift 25#, which is what it sounds like from her specificity.

Ordinarily I would say yes, that the reason to buy a lighter bike is because you want to ride a lighter bike, but if someone doesn't have the strength to lift 30# straight up twice in the same day, they need to work on their strength. A hybrid by definition is a "jack-of-all-trades," and light weight really isn't a criterion.

jjkkee, can you be more specific about what you need and why? You may be best served by a lightweight CX bike with road wheels, but without knowing what exactly you're looking for, there's no way to answer your question.
