This quest is triggered after you complete A Model Citizen. Pick up the Vault 88 Suit near the entrance of the vault. You can also find additional suits and Pip-Boys for your other settlers in the Vault 88 trunk. Transfer and equip the suit on Clem, and then find the Overseer to speak about the experiments. Using the prototype yourself will give you an Endurance Boost.
The Overseer believes that exercise is an inherently selfish activity and a societal ill. Her suggested cure is the Power Cycle 1000 experiment. Choose a location to build one Power Cycle 1000.
You'll also need to build a terminal and a generator to power both. Connect the generator to the terminal, the terminal to the Power Cycle and boot up the terminal to choose your parameters for the experiment.
All of the Overseer's experiments have three parameters you can choose from. Your choice of parameters will affect the final version of each object, which will be permanently added to the Workshop.
Power Cycle 1000 Parameters
Additional Power Production
Choose this parameter to administer electric shocks when the subject's rotations per minute dip below acceptable levels. It encourages faster cycling and increases the amount of power generated.
Sustained Usage Incentives
Choose this parameter to administer discret Buffout injections. It helps the subject pedal longer, faster and classically conditions them to associate the effects of the drug to the cycling.
This parameter uses aromatic essential oils and a soundtrack of gentle waves in the hopes that positive feedback will naturally help encourage productivity. The Research and Development notes indicate this approach was developed against objections and deemed a dismal failure.
After selecting your parameter
After you select your parameter on the terminal, the same series of events will transpire. Clem will come to the Power Cycle's location and ride until he blows out the power in the vault and the Power Cycle breaks.
Toggle into Workshop Mode to repair the Power Cycle, and then report back to the Overseer who will have different commentary depending on which parameter you chose.
Completing the experiment with any parameter and reporting back will complete Power to the People and trigger The Watering Hole.
