When you load the panniers of your bike before a long trip, it’s difficult to ensure that the weight is equally distributed.
This is also important, so that the machine is safely rideable.
Today’s invention is a balance for the parcel rack on a bicycle.
This has a fulcrum and a lever arm.
The panniers can be filled and the arm slid from one side towards the other until the bags exert equal turning effects clockwise and anticlockwise.
The arm is then locked in place before cycling off.
