I just bought my first bike in probably a decade (Schwinn Discover hybrid bike). There is a quick release for the front wheel. The skewer had a nut, lever, 2 springs, and these 2 washers on it. The instructions explain all the other parts, but don't mention the washers. Any idea what I should do with them?
Those washers help prevent your axles from dropping out of the dropouts if your quick releases become loose. In the USA, the CPSC requires some sort of secondary axle retention device -- if you don't have "lawyer's lips," you're likely to have these.
With some solid axles, they also help a bit with the axle nuts not loosening by themselves.
With ebikes, they can serve as antirotation washers, preventing the torque of the hub motor from twisting the axle loose.
They should be flush against the outside sides of your forks, right next to the bolts. There should be a notch in the fork or dropout in which the indent fits. The photo is of solid axle rear dropouts so just imagine them in a vertical orientation with front quickreleases.
