How do you remove the fork on a bike? Could never figure it out ? Answered

From the head stock

There are lots of loose ball bearings in there so be prepared to catch them in or on something.

there is a lot about servicing bikes on line if you look

More modern bikes may have a different arrangement where the headstock is held together with a long Allen bolt and have spacers to set the handlebar height. generally called a threadless head set.

You can look up how to dismantle them on line.
