The reason they are using the versa may be because the output shaft on a versa is actually a .5 hex, which is an ID that banebots sells their wheels with.

Locking a stage in a planetary gear is fairly simple - look up how people did it with globe motors. It involves glueing the sun gear and planetaries together with something, then dremeling off the teeth of the planetaries so they don't touch the ring gear.

FYI, you can't really be guaranteed that you can direct drive a banebots with a cim without installing an insert and broaching it with a keyway. The unfinished bores on the banebots wheels are not actually a measured diameter: it varies. They ream it to .375, but in most cases it comes bigger than the 8mm shaft of a cim from their manufacturer, and hence will not work directly on a cim.
