In the context of bicycles and motorcycles, caster is more commonly referred to as "[[Bicycle_and_motorcycle_geometry#Steering_axis_angle|head angle]]", "rake angle" or "rake and trail", especially in [[American English]]. The terms caster or castor angle are still predominantly used in [[British English]].

Some bicycle constructors refer to the angle subtended by the mechanical trail at the wheel center as caster.<ref>{{Cite web|url=http://www.bikeforest.com/CAD/caster_angle.php|title = Arctan(Trail/Wheel Radius)}}</ref>
