Knee hitting isn't unusual with bars that go back, an upright riding position, and when riding very slowly around turns (though the bar ends make it happen at a shallower turn angle). I have a 78cm PBH and it has happened to me with: Bosco on a Clem, Bosco on a Bubbe, Albatross on an Appa, and Billie on a Hillsen. It shouldn't be happening at speed since one tends to steer by flopping the bike sideways rather than turning the handlebars.
