A wheel chock is formed from a bar which is bent to form opposing bottom arms; a first pair of opposing side arms which run above the bottom arms and are slightly upturned therefrom: a second pair of opposing side arms which run upwardly from the first pair of side arms; and cross arms forming a top portion which runs between the second pair of side arms. A base plate is attached to the bottom arms, this base plate having studs attached thereto and extending from the bottom thereof. The studs fit into a track fixedly attached to the floor of a transporting vehicle which may be an aircraft or a truck. A central plunger latching member which is spring loaded also extends from the bottom of the base plate and latches the plate to the track. The chock can thus be installed in and removed from the track merely by manually positioning the latching member. A wheel of the cycle is fitted into the chock with its lower portions kept from moving sideways by the side arms of the chock and with the middle portion of the wheel prevented from moving longitudinally in a forward direction by the cross arm.
