1. Make bagels: Combine water, flour, sugar, salt, vegetable oil, and yeast in the bowl of a stand mixer fitted with the dough hook. Mix on low speed until dough is well-developed, about 8 minutes. To ensure the gluten has developed fully, cut off a walnut-sized piece of dough. Flour your fingers, and then stretch the dough: if it tears immediately, the dough needs more kneading. Fully developed dough should form a thin translucent "windowpane."
2. Transfer dough to a lightly oiled bowl, cover it with plastic wrap and a kitchen towel, and let rise for 2 hours.
3. Punch dough down, place it on a lightly floured work surface, and use a knife or dough scraper to divide the dough into 6 pieces (or more, for smaller bagels). Roll each piece of dough into a sausage shape about 6 inches long. Join the ends to form a circle. Repeat with the remaining dough, and let the bagels rest for 15 minutes.
