JHop Technique Help

Im new to the sport. im trying to learn some new skills to make my rides more enjoyable. I cant seem to complete the jhop. In the video on this site is says for step one to try and suck up your rear end while moving slowly. i cant do this at all. I was wondering if there are any tips on how i can make this happen.

When i try, i find myself jumping off the pedals rather than picking the rear of the bike off the ground. i feel i need this skill because if only helps in other areas and without some extra strength glue, im fairly far from completing the skill.

Any ideas?

Thanks.

    What the hell is a jhop? do you mean bunny hop?

    Start by doing them static (both wheels at the same time), just a few inches of air until you can keep your feet on the pedals.

    When you go for a proper bunny hop, make sure its all one motion, pull up the front (about 3/4 wheel height) and scoop the back up whilst you are still pulling up on the front, don't wait until the front is up and then try and scoop the rear.

    If you have access to a bmx try that until you can do it and get a feel for it.

    Is a 'jhop' where you hop out of a manual? I've not quite cracked it yet but I'm getting more comfortable with the technique now. The way it was taught to me is;
    1 - you are not trying to pick up the front wheel, you are to throw the back of your wrists forward and as your arms extend, they come up and around so you lift the front in a circular motion.
    2 - as your arms extend and come up, the front lifts, your arse is pushed backwards and you allow the bike to accelerate forward underneath you. Your shift in body weight towards the back lifts the front wheel and leaves you with bent knees over the back wheel
    3 - as you approach the balancing point between your body weight ove the back and the rising front end, you counteract the rising front wheel by extending your legs and then tucking up the back wheel.
    4 - it should be really easy once you can get to the balancing point to push off the back wheel, it should follow you but you can help it by pushing the bars forward, or by pointing your toes down and picking up the back end.

    I can do this every now and then, and can get a few inches but I can feel how powerful I could make the hop if only I can time my 'takeoff' over the balancing point. My tutor can jump like mad on it.

    By the by, if you watch old trials videos, you can see all the riders do this same technique where from static, they just sit their arse right back over the wheel, the shift in COG brings the front wheel up and as it does so, they extend their legs and push off. They can leap whole houses in this manner.

    I'll assume you have some decent flat pedals that dont let you feel slip off - if you dont get some.

    The way I have taught people this technique in the past is to pretend you are trying to scrape **** from your shoes. Point your toes down, and curl them over the pedals (not literally, but in your shoes), then pull your feet back and up as if you are trying to scrape crap from your shoes. At the same time you need to lurch your upper body forwards and up slightly, pivoting around the handlebars.

    Give that a go (lots of practice) and that will get you off to a start. With more experience you'll get more feel for it and learn you dont need to do it so exagerated as I describe.

    Make sure you can nail this at slow speed before you start to pick up the front of the bike or trying to hop at all.

    Thanks guys.

    Ill try with the pedals first.. I might have to look into a better set.

    A JHOP is a bunny hop, yes... but as i understand it, and keeping in mind that im new to the sport, a jhop is lifting the front of the bike off the ground and then the back half as opposed to the traditional bunny hop where both tires come off the ground at the same time.

    Thanks all..

    I've never heard it called a jhop, it's still a bunny hop.

    If I cast my mind back (many, many years ago) to my yoof, I started by just trying to scoop the rear wheel up- just as Chris'l describes. Then once you get the knack of that combine it with lifting the front...

    I saw the how-to vid for it the other day. I think its meant to be more a manual into a rear wheel lift. Essentially an overexagerated bunny hop, but not quite the same technique. Fundermentals are fairly similar between the two.

    JHOP - is that like the Japanese version of IHOP? :D

    Anyway, the principle or logic behind it as I understand it is best demonstrated off the bike. Stand beside it, quickly pull the front up and push it forward. Notice the back? It comes off the ground to follow the front.

    As I understand it, that's the key. Let the physics deal with it. The same principle apparently applies to jumps.

    I can't do it however, not as a bunny hop/jhop but I have a hard time getting the front off the ground anyway. Works on jumps and they are much the same really when you think about it.

    Nope that was never a bunny hop, front wheel then back wheel even back in the 80ies, but we all got confused and called it a horse kick!

    Lifting both wheels at the same time is considered a sh*t hop! (not my words)

    yep this what my bmx riding mate keeps telling me.

    The scoop with the rear is meant to just allow the bike to pop up, not to actually drag the backend up. But learning to drag the back end up is what teaches you the correct motion to use
