What term describes the dangerous event of pitching forward on a Penny-Farthing?

Answer

Taking a header

Taking a header was a common and terrifying risk for riders of the Ordinary, or Penny-Farthing. Due to the very large front wheel and the high seating position, any sudden obstruction like a pothole or the application of the brake could cause the rider to be thrown forward over the front wheel. This inherent instability made the Ordinary a risky machine, ultimately necessitating the invention of a design that prioritized rider safety through a more stable architecture.
