Are apes bipedal

Most apes 'can' be bipedal, in that their hip joints allow them to put their legs directly below their body. Chimpanzees, Bonobos, Orangutans, Gibbons and Siamangs will willingly walk on their hindlimbs in a bipedal fashion to some extent (particularly the gibbons!). They usually braciate or knuckle-walk (depending on species) for preference. It is only humans that are bipedal the majority of the time.
