air Resistance is proportionate to velocity squared, so air resistance is dominant over a certain speed, but below that speed it will be rolling resistance that is the biggest factor.
At 12mph, 80% of your effort goes into overcoming air resistance on a cycle.
On a level surface it is rolling friction. If you arte going uphill it is gravity plus rolling friction
If a moving object slows down, as in this case, the most common cause is that it is friction that slows it down.
friction
It was released as heat
Friction is that force.

Three things work to slow down a bicycle: wind resistance, rolling resistance, and tire resistance. As you ride along the air behind your back creates a vacuum. That slows both you and the bicycle. Each time the bicycle hits any type of bump, it provides resistance against a tire. That increases rolling resistance. The bicycle rides on the bottom of the tire. It is flat against the ground. To stay that way, the tire flexes. The energy used as the tire flexes slows down the bicycle.Because of losses. The tires steal some energy as they squish under the rider, the bearings drag a little as well, there's wind resistance too. As soon as you stop pedalling there's no longer any force countering these losses and you'll coast to a stop,
Using brakes slows your speed.
The limiting frictional force is the force that slows down the tennis ball on the roller coaster.
