The bike that grows with you? Unfortunately, that's just as much nonsense as a helmet that grows with you. We don't want to denigrate our competition. Just this much: unfortunately, a child is far too often put on a bike that is far too big far too early.
When a child has grown about 10 to 15 cm, the bike no longer fits perfectly. In addition, there is a transition zone of about 5 cm up and down. Children grow out of their bikes like they grow out of shoes or helmets. At NIZE, you benefit from the experience of our Whizzz Store, where we collect and evaluate our own statistics and research on the perfect bike size.
