I have a new old timey bicycle dynamo ( i think thats what it was built for) that when spun by contact friction from the bicycle tyre turns the DC generator and lights your light proportional to your pedal speed - standard old timey bicycle lighting system (thank you Mr Max Plank et al for inventing theories that invented LED,s TBH).
Anyhoo I have put the bike on rollers so it's stationary and putting lots of different light bulbs on it because reasons.
When I put lots of bulbs on the power required of my legs to light the bulbs obviously increases but i was amazed how hard it becones to pedal with the increased power requirements.
What physically makes it harder to pedal when trying to supply the power. It's like pedalling in quicksand.
