Friction which causes heat.
Yes, as the bicycle rolls down the hill, there is still some friction present between the wheels and the surface of the hill. This friction helps to slow down the bicycle's descent and eventually bring it to a stop.

If you are asking about the method of turning your front wheels into the curb when parking on a hill, it can help reduce the risk of brake failure.
Don't leave the engine on. Set the parking brake and turn the wheels toward the curb.
Turn your wheels heal toward the curb, set the parking brake. This way, if the brake fails and transmission slips it will not roll into traffic.
When parking on a hill, always set your parking brake and turn your front wheels toward the curb if facing downhill, or away from the curb if facing uphill. This helps prevent the vehicle from rolling if the parking brake fails. Additionally, it's important to put the vehicle in gear or, if it's an automatic, in "Park" mode for added security.
When your parking downhill you always turn the wheel to the right no matter if there is a curb or not. When your parking uphill you turn the wheel to the right if there is NO curb. If there is a curb you turn the wheel to the left. Hope it helped.

The energy stored in a bicycle at the top of a hill is potential energy, which is due to its position relative to the ground. This potential energy can be converted into kinetic energy as the bike descends the hill and gains speed.

You want to park the car with the front wheels turned toward the curb so if the emergency brake were to fail the car would simply roll into the curb and stop. Put the car in first gear if it is a manual tranny and set emergency brake.
The force of air resistance and friction from the ground act against the motion of the bicycle, eventually bringing it to a stop on a level surface. The energy that was gained while coasting down the hill is gradually lost in the form of heat due to these opposing forces.
