My son the trike has wanted from Santa Claus. He is six years old, 1.16 m but not the biggest. The assembly was a bit tricky on the steering wheel. An assembly video on the Internet has helped us after we had jumped from a terminal to a fastening part and we have not understood it alone, as this part is to be tuned reinserted. Then it was easy. Our son has a seat on the forefront of setting, so the future still a lot of space, since each extended leg is really almost fully extended. As long as there is not much going uphill, it is also pleasantly easy to drive, I suppose, more easily than a heavier Kettcar. The trike is also used in the friends of our son good. There is also no problem with brake and freewheel (as mentioned elsewhere), so that even more rapid descents are quite possible.
