The potential energy of your mass elevated in a gravitational field is converted to the kinetic energy as your mass is put into motion due to the acceleration due to gravity. The kinetic energy is then converted to thermal energy (hot braking mechanism and warm tires.

Homework!
Potential energy - the bicycle on top of the hill
Kinetic energy - the bicycle rolling down the hill by gravity
The brakes convert mechanical energy (wheels turning and momentum of bicycle) into heat energy with friction.

Gravitational energy (the energy from the force of gravity) and kinetic (the energy of motion).
Friction (between the bike and the air and road) transform a small amount of the gravitational and kinetic energy to heat (thermal).
When the brakes are applied, the friction transforms more of the kinetic and gravitational energy to thermal energy.
