You may not think of it until you need it but the headset fork bearing for the Xiaomi Mi M365 electric scooter does a big job. This 1-9/16" diameter ring bearing allows the handlebar assembly and front wheel fork to pivot smoothly in the frame.
Note A: Unlike standard shrouded or shielded wheel bearings, a headset fork bearing requires a nice coat of lubricant for best functioning. Any moving part can eventually wear out but a little grease will enhance their longevity.
Note B: This may also be compatible with M365 clones such as the rental scooters used by Bird, Lyft, Spin, and others.
