Compare that to the step through frame shown by the OP. Do you see any difference? I do:
-The distance between the top tube and the down tube at the seat tube on the step through frame is much smaller. This will greatly reduce the resistance to twist in the frame.
-The seat stays contact the seat tube at the same location as the top tube, not so on the step through frame. This will cause the seat tube on the step through frame to flex under the load of rider weight and pedaling.
While the differences are probably not a big deal to the OP’s wife, don’t pretend that the differences (in weight and stiffness) are insignificant to a serious rider.
