I’ve decided to buy a bike for my mother! For health improvement of course (and you all thought for racing hah?). Yes, I know it’s so sweet of me, however, she has no place to store it and I want to buy her a folding bike http://www.dahon.com/folding-bicycles-us-models.htm. Click on Vitesse D3. Here is my question: Will the “different” geometry and sitting position of this folding bike do the same job in health improvement as well as a regular frame geometry? Meaning weight loss, muscle gain.
