Compatibility between motors, wheels and hubs

Hi, I’m looking for components to build a robot and I’d like to know if these parts are compatible each other:

robotshop.com/eu/productinfo.aspx?pc=RB-Ban-183&lang=en-US
robotshop.com/eu/productinfo.aspx?pc=RB-Ban-140&lang=en-US

Thank you very much! :smiley:

You would need RB-Ban-141 (0.75" hex) for the hub that you chose. Note that the hub is two wheels wide as opposed to one wheel wide.
