I question that it is easier because then you have to worry about the chain loosing contact with either the middle or the back wheel. on the direct drive you only need to make sure the output shaft is the right length and this makes it really easy to make duplicate sides and parts cause they will all be the same size and postion. All you have to do is switch the positive and negative into your h-bridge or what ever you are using to control the motors.
