To solve this problem, we can use bitwise operations in Python. Here are the steps to solve this problem:

1. First, we need to create a mask that has N lowest bits set to 1. We can do this by calculating 2^N - 1. In Python, this can be done using the expression `(1 << N) - 1`.

2. Then, we perform a bitwise AND operation between the given integer and the mask. This operation will keep only the lowest N bits of the integer and set all other bits to 0.

Here is the Python code that implements these steps:

```python
def extract_bits(X, N):
    # Create a mask with N lowest bits set to 1
    mask = (1 << N) - 1

# Perform a bitwise AND operation between X and the mask
    result = X & mask

return result

# Test the function with the provided test cases
print("Result: ", extract_bits(85, 2))  # Output: Result: 1
print("Result: ", extract_bits(127, 4))  # Output: Result: 15
```

This code defines a function `extract_bits` that takes an integer `X` and the number of bits `N` as input, and returns the value of the lowest `N` bits of `X`. The function first creates a mask with `N` lowest bits set to 1, then performs a bitwise AND operation between `X` and the mask to extract the lowest `N` bits. The function is then tested with the provided test cases.
