How to fix 'Type of conditional expression cannot be determined'

Question

I am getting the following error:

Type of conditional expression cannot be determined because there is no implicit conversion between 'Car' and 'Bike'

public interface IVehicle
{
    int Wheels { get; }
}

public class Car : IVehicle
{
    public int Wheels => 4;
}

public class Bike : IVehicle
{
    public int Wheels => 2;
}

public Garage()
{
    var licenseHeld = false;
    IVehicle vehicle = licenseHeld ? new Car() : new Bike();
}

Why cannot this conversion be done when both Car and Bike implement the same interface?

The type of consequent and alternative must be the same, or there must be an implicit conversion from one type to the other.
