Motorpsycho and Up! represent two very different tendencies within the Meyer filmography.

This is a rather tedious Western with whacked-out nutcases on bikes substituting for the Indians.

One of Russ Meyer's black-and-white "Gothic" films, 'Motorpsycho' is down-and-dirty, but looks great and has a pulse-pounding energy.

If nothing else, Motorpsycho should be acknowledged (but generally isn’t) for helping kick off not one but two exploitation genres -- and I’m not even including the usual Meyer classification of sexploitation.
