Just to give you a heads up ...
These ESCs are meant to be installed in RC aircraft. The propeller wash is used to cool down the controller. If you dont mount a fan on your ESC it will eventually fry.
The shaft on the motor is not designed for the stress the chain is putting on it. You will need to lengthen the shaft and add support on the other side of sprocket.
