I posted a thread in the ebike section concerning riding an electric bike for my womanly 5'2" , 300 lb stature. I received a lot of good advice and decided to order a bike from online that my son recommended and try it without a motor and if still feeling I needed the electric motor to put one on. That said.... I searched and searched and thought I was doing the right thing and ordered a 16 size woman's bike. Of course, when I went back on the site, I noticed I should have ordered the 14 size and they are closed for the weekend. Is this bike going to be to hard for me to ride due to the size of this frame? Can the size make that much of a difference?
