As for Kettler, we got that years ago for my daughter who is now 8 and I was so disappointed in it. Maybe they have changed the design, but the problem I had was that the pedals didn't move if the child was pushed in the tricycle. I think the company sees that as a plus because they sell the bar that can be inserted into the trike to use as a push handle (making the trike a pseudo-stroller), but it made it very hard for me to teach my kids how to pedal. At least with a regular tricycle when you push them as they learn they can at least see how the pedals go around when the wheel moves.
