wherein the truck is configured to:
extend at least partially into the barrel through the barrel channel to engage the bolt, and
slide along a channel extending along a length of the crossbow parallel to the barrel, the truck extending from the channel and into the barrel channel.
2 . The crossbow of claim 1 , wherein the bolt magazine is further configured to direct the bolt of the plurality of bolts to a chamber of the crossbow such that the truck can engage the bolt of the plurality of bolts.
3 . The crossbow of claim 1 , wherein the draw assembly comprises an electric motor configured to move the truck to engage the drawstring and move the drawstring to the cocked position.
4 . The crossbow of claim 1 , wherein the draw assembly comprises a release configured to engage the truck, the release comprising a trigger configured to cause the release to disengage the truck when the trigger is actuated.
5 . The crossbow of claim 4 , the truck being connected to the drawstring, wherein when the drawstring is moved from the cocked position to a fired position, the drawstring transfers an elastic energy from one or more limbs to the truck and the truck transfers at least some of the elastic energy to the bolt.
6 . A crossbow system comprising:
