Cycle racks

Hi everyone,just got 2 new electric power assist bikes but I am struggling with best way to carry whilst towing.They weigh about 42kgs and I reckon with an empty front locker I can safely carry them on the A frame without exceeding my noseweight.I am concerned that such a set up might cause problems when turning with rear of car catching the bikes.Does anyone have experience and a recommendation for a suitable model if there is no problem?Thanks David F
