After reading and watching the reviews for both of these bikes, they seem identical. The IZIP is less expensive. I am an out of shape, short, overweight woman who has always loved bikes, but cannot handle even the slightest incline. I will need to be able to get it onto my bike rack so I can putter around the state park while we are campground hosting there. I would like a class 2 bike. Appreciate any input on these, or other similar models. Thanks from hilly northeastern PA!
