Hydraulic Bike by Dave Harburg

This was designed to be a replacement front wheel for any 27inch bicycle. It stores braking energy, and later at the touch of a button releases the energy for a launch. One braking deceleration from 20mph down to 0mph will provide enough energy to reaccelerate the bike up to 15mph without pedalling and without battery power !
