Man needs to do some form of physical work in other to remain healthy, this work is similar to the work done by any machine or equipment and thus should be channeled to give useful output, but rather, it is usually dissipated into the environment in form of heat. The regenerative bicycle ergometer takes advantage of the greater power generated by the limbs and arms, thus conserves, converts and stores the energy dissipated by the rider with an ideal mechanical advantage of 7.6, it strategically uses simple mechanisms to magnify its work and then converts this mechanical energy into electrical energy by the use of a dynamo, with a speed ratio of 108.5 and a transmission efficiency of 89%, the rider pedals 27rpm to obtain the dynamo’s rated input of 2600rpm, giving an output of 12.6volts. The regenerative bicycle ergometer is designed and constructed to perform all the core functions of a bicycle ergometer, having an allowable load of 116.5kg and a maximum resistance of 65.33N which is equivalent to a mass of 6.66kg. The energy converted is stored in a 12volts battery, making its use flexible, clean and meeting the energy demands of man.
