Not enough power

First, I will start out by saying you can do anything you want to do.

With that said, I would highly recommend against using the globes for drive motors. The main reason is they do not have the power to justify using them.

Second, by gearing up (increasing speed) you are double dipping on gear ratio. What I mean by this is that the gearbox attached to the globe motor already has a pretty big reduction, so you are "reversing" that ratio to get more speed .. very ineficient.

Last, the shaft on that motor can't take any side load so you need to add another bearing.

It is too much work for not much gain.

If you are going to pick drive motors use the Chiaphua, drill, or Fisher-Price or any combination of the three.
