Good wheel defects

In the first year everything was great, but our impeller is always indoors and is not exposed to moisture. The turn radius is limited, but what I personally feel is also very good. I prefer when the metal impellers, where the driver can turn on its own axis.

Nerve point is here with us the saddle from sliding deeper again. No matter how determined you turn the screws (and ours are quite strong in the wood inside) - he slides every few weeks back down. Meanwhile, we have built between washers and put their own screws, but really good is something else.

If the impeller cost only 50 euros, I could certainly live with it very well. At twice the price so what is not but. We have now bought us as 2nd runner for the brother of one United Kids for 50 Euro. This has holes instead of continuous adjustment and will hopefully not slip. The big brother is already test driven and said that it travels much better than his (ie the BambinoBike).
Expensive so do not always seem to be good.
