Best Pedal Kayaks For 2024

A pedal kayak is any kayak that uses foot propulsion—by means of a pedal drive that turns a propeller or moves fins under the hull—to power the boat. Most pedal-powered kayaks can also be propelled with a paddle, although these boats tend to be wider and heavier than standard paddle kayaks, making them less efficient and harder to move with upper body muscles.
