Have you measured your peak output power while pedaling?
How is the printed sprocket holding up?

Why remove the wheel rather than spinning a smaller wheel or drum against it? This method would give you better RPM on the generator (the bicycle wheel and drum are essentially a very large gear and much smaller pinion) and it wouldn't require disassembling the bike.

I did it with a drum and immediatly dismantled it because the sound and vibration generated by the bicycle tire is just too bothering (unless you live alone).

That's not a bad idea, but I wanted to keep as much as possible printable and I couldn't think of a good way to 3D-print a drum assembly. Suggestions welcome!
