When you pull your front tire up you pull the back up with the pedals

Lock your arms straight!!!! And lower your body. Like if you were going to manual. As soon as that front wheel comes up, jump up with the bike. Tighten your grip and twist. If you pull up the bars hard enough towards your chest you will feel the rear wheel pop! But if you pullback like a manual and then pop up you will feel that motion your looking for!!! And bunny hops become 100 times better if you learn to manual first.

Try doing endos of a curb, This teached me how to lift up my rear wheel.

Try to angle your feet downside then crouch a bit and try to lean forward and push ur arms forward

So when you gwt you front wheel in the air what you need to do is push your part forward and just a little bit then your wheels should pop up also you should just try doing it while stood over the bike while staying still

Use your arms to get up the back wheel while bending your legs

Try to twist your bar forward and point your toes downward

Try learning how to endo, even just an inch. Then pull up your front wheel and lean forward and scoop up your pedals with your feet as hard as you can.
