Using ERG Mode to smooth out pedal stroke

I am wonderjng if you can set a minimum wattage for a ride. I am trying to coach a 14yr old that has irradic pedaling I want to set the minimum watts at around 90 so he can’t just drop out. Any suggestions.

ERG mode workouts have a target Wattage for each segment, so it’s not really a minimum - it’s a number you need to get close to in order to complete the workout. I’m not sure if that would satisfy your needs.

Modern cycling computers can be used to generate an alert when you are not meeting a minimum power level. For example:
