Is there a difference in the tendency of the wheels to lock?

In German traffic rules for motorcycles and bicycles, it is important to know that the rear wheel generally tends to lock first when braking hard. This happens because the weight of the vehicle shifts forward during braking, reducing the load on the rear wheel and causing it to lose traction more easily. The front wheel usually stays in better contact with the road and requires stronger braking force to lock. Understanding this helps drivers apply brakes properly to maintain stability and control, preventing skidding or loss of control.
