What's the best way to add a battery like device to a dynamo light (lemmy.world)

Hello everyone, I bought a bottle dynamo for my bicycle with a rear and front light. Though I have one little tweak that I would like to add and that's a way to keep it light up for about 1 minute (at least 30 sec) without pedaling. I thought of putting a capacitor in the circuit to store some energy but I would like what do you all think of it ?

Thank you for your time and have a nice day you all !

I could be wrong, but wouldn't the capacitor keep it from turning on until charged?

Yes but it should not be like 30 seconde long I think, so it should be OK for a bicycle :)

It should be possible to wire it so that when the battery is on, the light turns on instantly while also charging the capacitor. Battery meaning paddling
