We opted for this Kettler Speedy because it is first, Adjustable height which is not the case always, the quality of Kettler is known and have not given to last because of the good reviews the other reviewers here on Amazon.
We were not disappointed. My daughter was not to get down for the rest of the year from the impeller and walks are thus turned out really nice. A Day at the Zoo? No Problem! Come take impeller and no longer had to carry my daughter or waiting for them but had more to do with her afterward because they DIR quickly so has the way! This one can adjust the height of the impeller is also grown along perfectly with her. Six months after my daughter started with the wheel, we have been given a normal bike for them and at first I was thinking that it is probably still too small 3.5 years. She's always wobbled back and forth and has fully supported on the support wheels. But she was so enthusiastic about the bike that I thought "Okay I'll try to teach you." So I removed the training wheels have told her and showed how they occur and brakes must and am whole 5 minutes mitgerannt with her and have supported them. After 5 minutes I was out of breath, but they unwilling to quit and is simply moved on and only with jump but then without any help.
Since that experience, I am convinced impeller fan! Of course it is not the evidence that it would have taken longer without impeller or the switch working as well in every child but I'm excited. Now in the spring, our 2nd daughter took over the wheel and tried already busy with their almost 2 years so driving around. However, it is still a little too small for what their enthusiasm but not brake!
The build quality is top! I highly recommend this impeller each without limitation.
