> e-bicycle with a small roof can ride as long as the Sun shines

Is this true? I can go through a 630Wh battery in 2-3 hours of riding and I can't imagine current solar being able to keep up with that. I think you might get an extra ~30 minutes of riding, but not ~forever~ unless you mean pedal power.



Your mileage will vary, but the order of magnitude works:

I think you just confirmed for me that you don't know what you're talking about.
