Maybe in some contexts? But generally, no. Umět is about skill rather than ability.
"Are you able to ride a bicycle" is generally asking if you're physically able - for example, I'm not able to ride a bicycle when I'm tired, when I have a broken leg, or when someone's stolen my bike. None of those examples work with "umět". Even if I currently can't ride it for any of the mentioned reasons, I still know how - I still "umím jezdit na kole".
"Are you able to ride a bicycle" translates to "Jsi schopný/á jet na kole?" if it's about the immediate ability to ride it now or "Jsi schopný/á jezdit na kole?" if it's more general - to ride it at all.
