The wheel is made of imported PU foaming, instead of filling other padding, so its density and hardness are all balanced, let alone its durability.
The wheel hub is made of aluminum alloy and casting processed, much durable than other wheel hubs. We machined the hub again to make it to be out of roundness. Polish and electroplating treatment on the surface is to improve the density of wheel hub.
The wheel hub is composed of two separate pieces for users to change the tires conveniently.
