RSSTrying to encourage your child's tennis skills, but can't serve to save your life? Daniel Bauen uses a pedal-powered ball launcher. From his site:
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 is a unique innovate or die entry. It 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.

Most people I know can't just bike to their tennis court. They would have to load up this contraption in their SUV and haul it and the bike to the court. Secondly, most people that play tennis don't have a partner that would rather ride on a stationary bike than practice hitting the ball.
I understand why this product has not made it to market yet.
