Re: completely new
I think that if it was me and I was young, I would start out with a good multi speed pedal bike and ride it back and forth to work. Then when I had accumulated enough money I'd buy a magic pie electric motor which is super reliable and installs easily and quickly. The initial outlay for an electric bike is more, but there is virtually zero maintenance. If you could plug it in to recharge it once you got to work you're golden. The laws in most states are a lot more ebike friendly than for gas motored bikes.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
