My kids loved all of this wheel of Puky. In spite of not just pfleglichen handling multiple children, it is still in good condition. The children have made this wheel often simply fall to the ground (off) and never was something broken. The decision to purchase this Puky learner bike was definitely that the handlebar does not "turn on" can thus little bit protected. I recommend this impeller from about 20 months, for as the children come (if they are average in size) well with his feet on the ground. So, ages 4 and the wheel is then a bit too small.
I hope my review was helpful to you and help you to make the right purchasing decision.
