In a large bowl, combine the bread flour, yeast, sugar, and salt.
Gradually add the warm water and mix until a dough forms; knead until smooth and elastic.
If making cinnamon raisin bagels, knead in the cinnamon and raisins now.
Cover and let the dough rise until doubled, about 1 hour.
Divide the dough into portions, shape into balls, poke a hole in the center of each, and stretch into a bagel shape.
Bring a large pot of water to a boil, adding the barley malt syrup or honey if using.
Boil the bagels for 1-2 minutes per side, then transfer to a baking sheet.
Bake at 425°F (220°C) for 20-25 minutes, until golden brown.
