Water Cooled Motor

Could a a motor like this be the future of small fast turning motors ?

The one drawback I see with this one is that even the lower KV setting is way too fast of a KV for E-Bikes/E-Trikes .

There a quite a few watercooled small motor options on the market. Alien power systems offers watercooled versions of the more common ebike rc motors. The design considerations for use on a bike are always the same: does the cost weight and complexity of plumbing and radiator end up diminishing the benefits compared to just using a larger motor that doesnt require the watercooling?

In an rc boat you have free access to unlimited water and free pumping from the motion of the boat so its way simpler compared to the parts necessary to watercool a land vehicle.

I've definitely thought about watercooling a bike motor plenty of times but I always remind myself that simplicity is one of my favorite parts of electric vehicles.
