Depending on the application, you can view this as a pro or a con. If the goal is a longer duty cycle with weight being a non-issue, it's a pro.

The Mini-Bike CIM has a huge amount of mass, lower power, and higher efficiency than the CIM (and MiniCIM), which means it's far more robust. It being slower also means less reduction required to hit a given speed.
