Lowering the center of gravity in a gravity field of a moving

If this energy GOES somewhere, it's not potential energy.  It's
kinetic energy.

"...potential energy is stationary, with stored energy to be released;
kinetic energy is energy in motion, actively using energy for
movement."

By slowly lowering your center of mass, you are lowering your
potential energy.  Potential energy is where nothing is moving.  You
have the potential of moving but there's little or no kinetic (moving)
energy produced.  In other words, you cannot dissipate potential
energy without first converting it to kinetic energy.

If you rapidly descend onto your bicycle saddle, you do produce some
kinetic energy.  To answer your question, the kinetic energy is
absorbed by your tires.  Jump off a building and land in your saddle
and you will probably explode the tires, which is a good demonstration
of dissipating kinetic energy.

Note that both lowering your center of mass by slowly lowering
yourself onto the saddle or rapidly lowering it by jumping off a
building into the saddle are going to produce any forward motion.
