Both cleanly powered and built from 2 recycled bicycles, scrap steel and wood, leaking 5 gallon water jug and a lacross stick, our pedal powered tennis ball launcher allows players varying in skill levels to practice to be better at both tennis and cycling. The launcher is towed to the court on its built-in bicycle trailer. A bike is secured to it and functions to drive the device. Pedaling the cycle as one would on a trainer drives the two launcher wheels. The cyclist then aims and pulls the lever to launch balls to the hitter.
Created for the Specialized Innovate-or-Die Contest.
the whole point of a ball machine is so that one person could play alone with the machine. you might as well have the biker play the other player!
By xmikeyyc 1213887142 Reply Spam [+2] Moderate Up Moderate Down RemoveThis is for 2 people of unmatched tennis abilities. It's like having a tennis coach use a ball machine to launch balls at you. They could just hit with a racquet also, but it's more efficient to have a volley of balls to train your form.
