WooCommerce hide shipping method based on category advanced

I sell bicycles and parts. If someone buys a bicycle in the WooCommerce webshop only the shipping method ‘local_pickup’ should be visible. If someone buys a part only ‘flat_rate’ (shipping) should be available. If someone buys a bicylce and and a part only shipping method ‘local_pickup’ should be available. How should I solve this challenge with a new code snippet?

I have two snippets that work perfectly, but only do one part of the job…

// Hide 'Shipping' (flat_rate) with a bicylce in the shopping cart
    add_filter( 'woocommerce_package_rates', 'hide_shipping_based_on_tag' ,    10, 1 );

    function check_cart_for_share() {

	// specify the category id's you want to hide flat_rate
	$category_ID = array(
    '7', // Type A bike
    '8', // Type B bike
    '9', // Type c bike
    '10', // Type D bike

	);
	global $woocommerce;
	$cart = $woocommerce->cart->cart_contents;

	$found = false;

	// loop through the array looking for the categories. Switch to true if the category is found.
	foreach ($woocommerce->cart->cart_contents as $key => $values ) {
        $terms = get_the_terms( $values['product_id'], 'product_cat' );
        foreach ($terms as $term) {
            if( in_array( $term->term_id, $category_ID ) ) {

        $found = true;
        break;
    }
    }
    }

    return $found;

    }

    function hide_shipping_based_on_tag( $available_methods ) {

	// use the function above to check the cart for the categories.
	if ( check_cart_for_share() ) {

    // remove the method you want
    unset( $available_methods['flat_rate'] ); // Replace "flat_rate" with the shipping option that you want to remove.
      }

	// return the available methods without the one you unset.
	return $available_methods;

      }

and

// Hide local ickup (local_pickup) with parts in shopping cart
     add_filter( 'woocommerce_package_rates', 'hide_shipping_based_on_tag' ,    10, 1 );

     function check_cart_for_share() {

	// specify the category id's you want to hide flat_rate
	$category_ID = array(
    '11', // Parts

	);
	global $woocommerce;
	$cart = $woocommerce->cart->cart_contents;

	$found = false;

	// loop through the array looking for the categories. Switch to true if the category is found.
	foreach ($woocommerce->cart->cart_contents as $key => $values ) {
        $terms = get_the_terms( $values['product_id'], 'product_cat' );
        foreach ($terms as $term) {
            if( in_array( $term->term_id, $category_ID ) ) {

        $found = true;
        break;
    }
    }
    }

     return $found;

     }

     function hide_shipping_based_on_tag( $available_methods ) {

	// use the function above to check the cart for the categories.
	if ( check_cart_for_share() ) {

    // remove the method you want
    unset( $available_methods['local_pickup'] ); // Replace "local_pickup" with the shipping option that you want to remove.
      }

	// return the available methods without the one you unset.
	return $available_methods;

       }

With kind regards,
