Well.. There is surface friction from the tires on the road, there is air friction from the bike itself ,, more air surface friction if your on it.. Then there is mechanical friction through the resistance of the, chain, bearing assembly grease in axle.
friction
We would need to know what the friction is to affect to respond to this question.
ice can affect friction
Speed does not affect the force of friction.
surface friction and sliding friction
Friction will slow it down
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
The nature of the surface. A measure of this is the coefficient of friction.
the smoother a surface is, the less friction it produces.

it doesnt
As water in the stream channel flows, it encounters friction; the friction slows the forward movement. The shape,size, and roughness affect the amount of friction. High friction slows the stream significantly.
