Which crossbow design is known for its simple structure without wheels or cams?

The recurve crossbow is known for its straightforward design that features limbs that curve away from the shooter when unstrung. Unlike compound crossbows, which utilize wheels and cams to assist in drawing the string, recurve crossbows draw the power directly through the bow's limbs. This design simplicity not only makes recurve crossbows easier to maintain but also offers a more traditional shooting experience, as it closely resembles the form of a traditional bow. Their simplicity can also contribute to lighter weight and ease of use, appealing to many archers and hunters who prefer a more direct connection to their equipment.
