My mother wants to get a tricycle (upright not recumbent). I thought a light weight bike with training wheels might give her the stability she wants in a faster lighter more maneuverable bike. One problem I can see is training wheels have to be set fairly high off the ground to permit turning as you have lean to turn a bicycle.

Any thoughts on a bicycle with training wheels for the elderly. Is it a bad idea?

Any experience with a tricycle, they seem to be very heavy and difficult to store, but I have never owned one.
