Dagu Wild Thumper Wheel


I’m trying to figure out the axle size, in millimeters, that this wheel will take without using the adapter. The shaft adapter it comes with converts it to 4 mm, but what is the original size?

I’m buying…
^ that motor. It has a 6 mm shaft. I’m also buying the aluminum hubs that fit this motor, but I don’t see how I could attach that hub to this wheel. These wild thumper wheels are the only good off road wheels I could find on this website.



The Wild Thumper wheel has a hexagonal cavity on the backside of its plastic hub that the adapter fits into, with a hole for the screw to hold it in place. You can see the cavity in this picture.

Unfortunately, we do not have a good solution for mounting this wheel on a 6 mm shaft.
