Use studded/spiked tires, or use snow chains for bikes. Or have someone walk ahead and spread sand on the susrface.
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.
friction
Friction which causes heat.
As a bicycle rolls downhill, the force of gravity pulls it downward, converting potential energy to kinetic energy, causing it to accelerate. The increase in speed is a result of the gravitational force overcoming the resistance from friction and air resistance.
The speed of a sled increases when going down a hill due to the force of gravity pulling it downhill. The speed decreases when there is friction between the sled and the surface of the hill, air resistance, or when the slope becomes less steep.

unless you have chains or studs it would be 0 friction
Pressure certainly does increase in a water line going down hill. This is because the weight of the water pulls it.
Friction increases or decreases based on the surface changes. If a box were sliding down a smooth hill that suddenly becomes quite rough, then friction would increase. It would be the same vice versa for decreasing friction.
if there is friction on the hill it will slow you down
No, the friction of a wagon moving down a hill is typically kinetic friction. Static friction occurs when an object is at rest and there is no motion relative to the surface.
Gravity and friction. You need to keep the accelerator pressed to compensate for loss in speed.
