After fall bicycle feels really slippery
For the most part, whenever the front wheel on a bike skids or slides at speed, the rider wipes out. The only people that manage to stay up right are either very lucky or have reflexes that Jedi warriors would be envious of.

If you are riding after a recent fall and feel like your front wheel is sliding, but you are still upright, then you have some sort of post-crash confidence hit, and are interpreting any motion as being an imminent crash.

Check that your fork isn't damaged, handlebars are aligned, and that your wheels are true, but otherwise just keep riding and rebuild your confidence.
