I have biking legs for cruise.
My knees were burning, my hands were cramping, my feet were cold, my ass was sore, and it was plus 2 centigrade on my last venture.
I have severe emphasima and I really don't want to pedal if I don't have to.
If the wind is at my back I can see zero amps coming from my display/controller.
That's when I go no hands and let the bike fly.
