Mechanical engineering

My six years old son had a two weeks’ vacation. So we decided to do a small project. I took the real wheel set of a broken toy quad bike to make a tricycle which is powered by a 12V car battery.
I decided to make a slight modification to the wheel set when attaching it to the frame of the tricycle. In the quad bike the motor and gear set are firmly attached to the frame. In the tricycle, I didn't screw the motor and gear set to the frame. Instead I attached it to a spring which allows the motor and gear set to move around the axil to some degrees in response to varying force.
My gut feeling is that this design has some mechanical advantage over the other. As you watched in the video the tricycle negotiated the obstacles and bumpy up hills better.
I have no qualification in mechanics or background. I don't know whether this design facilitated the motor and gear set to generate an increase in torque. Or the springs simply acted as clutch or differentials or both?
Or simply I am imagining things?
Please comment.
