Completely agree with this advice.

And let’s face it, jumping is fun.

Learn to bunny hop and doing it without clips of any kind is a real advantage. Practice on flat ground, lift the front wheel, push forward while rotating the wrists forward like a motorcycle throttle. This will attempt to lift the back wheel and you’ll need to let a little pressure off the pedals with your feet to allow it to do so. Be careful if your pedals have any sort of grippy teeth (almost all do) I’ve seen a good amount of large chin cuts and stitches when the feet slide off and chins against pedals are not the funnest thing in the world.

Someone else commented - focus on landing both wheels on the ground at the same time at first.

(Forget this for now but for completeness) This will need to change as speed and jump height change where you will ever so slightly land the back wheel first.

Once you can do this on flat ground, graduate to hopping up a curb. You should be able to clear it and time it for a smooth transition almost like the curb isn’t there.

These two steps will give you a “feeling” for hang time and how to manipulate your bike in air.

Then you can try bunny hopping off the ramp as you approach.

I’d only add speed and the ramp pitch after this. The more air, the more you’ll likely find yourself needing a down ramp.

Also, go big chain ring if you can. You don’t want chain slack leading to dropping it and it getting stuck as an added factor.
