Tic
Simple motor tics are typically sudden, brief, meaningless movements that usually involve only one group of muscles, such as eye blinking, head jerking, or shoulder shrugging. Motor tics can be of an endless variety and may include such movements as hand clapping, neck stretching, mouth movements, head, arm or leg jerks, and facial grimacing.
List of cycling records
Motor pacing is a type of human-powered record where a pace vehicle is modified by adding a tail fairing to keep the wind off the cyclist who is riding behind it. This type of record was invented by Charles "Mile-a-Minute Murphy" who drafted a train to set a record in 1899. A mile of plywood sheets was attached to the railroad ties, so Charles would have a smooth surface riding behind the train.
