Ukuthengiswa kwemibhobho yethu yokunisela ngenkasa kube kuhle kakhulu. Amapulazi amaningi amakhulu asicelile ukuthi sithenge imibhobho, futhi impendulo evela kumakhasimende yinhle kakhulu. Kunezinhlobo eziningi zemibhobho yemibhobho yokunisela ngenkasa, yonke eyenziwe ngepulasitiki. Phakathi kwabo, umbhobho wokunisela ngenkasa we-rocker-arm usetshenziswa kakhulu. Umgomo wawo osebenzayo ukuthi ingalo ye-rocker yombhobho ithinteka ukugeleza kwamanzi, ukuze ingalo ye-rocker igxume, nengalo ye-rocker ibuyiselwe ngokushesha endaweni yayo ngaphansi kwentwasahlobo, futhi umbhobho uzungeziswa ekhoneni elithile ngamandla we-inertial impact.
