Need one that will fit my 5'2" frame. I am 5'2", 130 lbs. My husband is 5'10" and 220lbs. A step through would be helpful. My husband could not get a good leg extension with the folding bikes that we tried. We are hoping to spend under 1500.00 each. We have a motorhome and tow a small SUV. We thought we could fold them and put them in the SUV.
