I do biketrial too, I just learnt my first pedal up last night lol.

I guess only pulling the rear wheel downward do initiate a jump?

You are right, I never realize there is a kicker.

Wow, this really solves the question in my mind. So the rear tyre becomes a kicker itself.

You do make a point. Btw does he pull up the bike with his ankle?

When somebody do a normal splatter which begins with the both wheel on the ground, I can still imagine the wheelie generates much up lift momentum to the center of mass to the bike. But this splatter begins with the front wheel already in air and he still can lift the bike over a meter 0_o

But it looks like the suspension rebounce and the jumping of the rider's body could only generate 20 - 30% of the whole lift force at most to me. How does the timing of the engine affects the lift in detail? Doesnt it only affects the forward force?

Does the swing arm actually rebounce with the aid of the engine? How does toni lift the bike to that height in terms of mechanical, body movement and physics?

I am sure that I still have a long way to go to learn the flip turns, I just have 8 months of trial motorcycling experience . I have a JTG300 to practice in my the local bike club and I am mainly practicing the basic and jap zap when I am on there. However, when I am practicing the balance at near home, I am using the gasgas tx200 randonne instead, it is extremely heavy

Thanks sectionone. I understand flipturn is totally beyond my current skill and I never want to try it at this moment. I just want to practice the hops after a landing and recovering the balance. I also can feel the front hops are easier and require less energy to do it.

Nice to meet you. I also have much good memory before 1997. By the way, the oldest trials rider in hong kong is 70 years old, and he does enduro too

@lineaway: no, I cant do all hops , and the local riders insist to tell me hopping on both wheels is easier than hopping on only front/rear wheel, as they are all practice hops on both wheel after they can do basic balancing. I doesnt want to rotate the bike in mid air, I just want to do those hops which stay in the same position or moving in sideway. @michael_t: yea, I have watched all ryan young video before, and I am following his instruction as the standard regardless how do other local rider's advise. I have the dvd of it . But it also has no instruction on how to do hops on both wheels.

Yea, I will try the way which u advised. But I found staying myself on the bike after 2 to 3 hops is rather hard.

Yes, I do practice the basics when I am in the trial club on weekends. But I really cant practice anything which requires the engine on when I am on the weekday evenings, there are no place in hong kong which allows me to practice except the private land of the trial club. So I just keep to practice balancing only. Thats the reason why I want to try the hops.

Yea, looking forward to meet you. You could reach me by visiting the hk trials club.
