It all comes down to gearing. The CIMple box has some advantages because it consists of only a single stage of gear reduction, then a single chain reduction to the wheel. Less stages = higher efficiency = less parts = less complexity = less weight.
However, this means the internal ratio is limited and it might not fit in some drive setups.
Have you learned about drivetrain gearing or some of the other considerations of drivetrain design?
What wheels do you want to use? Why?
What configuration do you want to use for your gearbox? (direct drive? gearbox + chain?) Why?
Do you want to push? Why?
Do you want to have a high top-speed? Why?
Do you want 1-speed or 2-speed? Why?
Once you understand some of the tradeoffs there and have a better idea of what gear reduction you need before your wheels, you can then make better decisions about whether the CIMple box works for your application or whether you need something with more reduction, or 2-speeds, or whatever...
If you want to email me, we can talk through the goals you have for your drivetrain, and I can help you understand some of the tradeoffs you'll need to make. Then we can talk about COTS/Custom options to achieve these goals.

Tough to have that back-and-forth on a forum.
