premise: He calls me back and proceeds to tell me that this is the second time this week " the bike has done that to him " , and he offers to sell the bike to me for $ 10 . I really have no use for a bike ( at least , I ' ve more use for $ 10 ) at that time , so I decline . Just to make him feel better , though , I agree that it 's certainly an evil looking bike . I start to head off again , and he calls me over again . Why does the man want to sell his bike ?
hypothesis: He really has no use for a bike .
