Try to add the next code in Theme Options > Theme custom CSS:
.single-product:not(.product_cat-elcykler) .product-content .price { font-size: 0px; } .single-product:not(.product_cat-elcykler) .product-content .price span, .product_cat-elcykler .product-content .price { font-size: 20px !important; }
