Abstract: A crossbow comprising a tiller, a prod and a trigger mechanism. The tiller comprises a butt and at least one track, and is configured to support a bolt. The prod comprises a bow; a bow string; and a bow base arranged to connect the bow to the track(s). The trigger mechanism is arranged to hold the bow string in a cocked state and to allow releasing the bow string and thereby shooting the bolt. Either the prod; the trigger mechanism; or both, are movably connected to the track(s) such that cocking the bow string utilizes the movable connection. The crossbow exhibits a predefined drawing weight. One crossbow comprises a force enhancing mechanism arranged to allow cocking the bow string with a cocking weight substantially smaller than the predefined drawing weight, utilizing the movable connection of the prod, the trigger mechanism, or both, to the track(s).

Abstract: A modular crossbow for shooting a bolt and a method of customizing thereof. One modular crossbow comprises a tiller; a prod comprising a bow and a bow string, the bow attached to the tiller by a prod fastener at a predefined prod location; and a trigger mechanism attached to the tiller by a trigger mechanism fastener at a predefined trigger mechanism location, the trigger mechanism arranged to hold the bow string in a cocked position and allow shooting the bolt by releasing the bow string. The prod fastener is configured to allow changing the predefined prod location along the tiller, and the trigger mechanism fastener is configured to allow changing the predefined trigger mechanism location along the tiller.
