Kenneth Henry May (born April 5, 1970 from Sacramento, California, U.S.) is a former American professional "Old/Mid School" Bicycle Motocross (BMX) racer whose prime competitive years were from 1985 to 2000.
His best known nickname is "May Day", a play on words involving his last name and the international call of distress Mayday which was in turn prompted by his hard charging "go-for-it" racing determined to come in first no matter what the cost.
It often lead him to be carried off the race track in a stretcher.
His being knocked out after a severe wreck (despite having a helmet on) during the 1986 American Bicycle Association (ABA) Grand Nationals being a case in point.
He often managed to recover quickly enough to be in the next moto (heat) of racing to take the win and transfer to the main.
Incidents like this also earned him the alternate nickname of "Mayhem", another play on his name and his predilection for wrecking on the race track and his aggressiveness toward other racers while racing and not.
