You're combining two different methods of doing this which will fail, need to choose one or the other, try this (Sorry for these not being in code boxes, my work PC doesn't like DaniWeb):

Change line 13 to:
return this.front_gear * this.rear_gear;

Change line 16 to:
document.write("this is a " + bicycle.gear_ratio + " speed bike");
