I can lose weight doing either one and I ride both ways. But it's more about matching calories eaten to calories burned. I ride in part
so I can eat stuff I like (all of which is fattening). Doesn't matter whether I burn that 350 calories on my bike with the motor or without - but
if I eat more than 350 calories over my baseline and don't do extra riding, I'll gain weight. Probably good that lots of places are closed
right now - less tempted to ride from bakery to bakery, lol.
