What the wheel does when its still under the guardrails is crazy!Pcyklopat said:This is the best 'proof' of 'professional' use I've seen. He even holds on to the bike with full force (right hand) after he tries to get back up, and when the bike is down second time the wheel still wants to spin.

he doesnt have much speed coming out of the curve and he actually accellerates whilst skippying his bike up the stairs.
good find, looks like a motor to my layman eyes.
would be interested to hear if somebody thinks that,s possible without a motor.

A bit like this one then? Slightlly more obvious bunny hops this time.kwikki said:OK, it's the Belgian steps at Valmont Park in Boulder. There are quite a few clips on YouTube of several riders doing it......but I have yet to find one later than 2014.......
Why should he? His bike is always going (nearly) horizontally, it never climbs. So no reason for slowing down much. Or in physics terms: The increase in potential energy (i.e. the climbing) stems from the little jumps and not from the kinetic energy (i.e. the velocity).MarkvW said:He isn't even pedaling.
kwikki said:Yes but he's got his brakes on it those clips.
In the cx clip his wheels are turning
Why don't you try it out yourself. I just did. I'm really no Peter Sagan but it didn't last long until I was able to do a a couple of bunny-hops in quick succession of flat terrain while rolling forward (without brakes on). And then I even managed a few steps. All there is to it is really being able to control your bunny-hops well enough so they're neither too short nor too long. As soon as your wheels don't land on the right spot but hit the edge of a step it's game over obviously.kwikki said:I genuinely have no idea about the possibility of this. I would have thought that repeated bunny hops would have required brakes on in order to brace against the ground.
Seeing her family, canary thiefs and EPO users, she had a setback from birth, really. Strong children can overcome such backgrounds, but most don't. She could change her name and retreat to a small village and work as a nurse for the demented, or something. I'm not sure in her place I'd not end up in a deep canyon or simply would never be found again.Brian Butterfield said:I wonder what will become of Van Driessche, who does not have the luxury of a silent ban.

There is no doubt that I have seen evidence of mechanical fraud, but the clinic has gone mad (er) with everything being the result of a motor. Hopping up those stairs is not that difficult (the spacing is perfect, they aren't too tall, or steep...). Everyone that I ride with can do that. As far as accelerating, I could start from a stand and do those stairs, so yes, I will be accelerating. Obviously its even easier coming in with a little momentum like he did. If you search YouTube, there are many CXers who do that on those steps and others like them. Most of the 12 year olds at the BMX park can do it as well.kwikki said:https://media.giphy.com/media/uGjzzKY4BhtKw/giphy.gif
