The correct abbreviation is "km/h", so kmph is closer to the correct one than kph. kph seems like a measure of insane acidity.

  If it's about bikes it's obviously about pressure of the tires: kph means kilo-pascal hours. In other words, accumulated pressure over time.

    This sounds like the opposite of my bikes, where the pressure vanishes suddenly, too often.
