this, but then vice versa.

we,ve gone throuh this thousands of times. He may or may not have used a hubmotor, but the video rebuttals are plain insults to the brain. The one by A. Rasmussen is so dumb it just reeks of omerta and only feeds the suspicion that Ryders bike was forged.
Scienceiscool is bang on the dough here.

This is the best 'proof' of 'professional' use I've seen. Why don't other teams/riders speak up about this obvious fraud?? Froome on Ventoux isn't full on proof, but this Movistar rider is just too obvious.
The women seem to do it in the LA case.

Re:

What the wheel does when its still under the guardrails is crazy!

lol, who,s that?
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.

 

[kwikki]

I've no idea, I just saw it on the dreaded FB and thought it would give people here a giggle.

If it was Danny McAskill riding it would be 100% legit

Yes but he's got his brakes on it those clips.

In the cx clip his wheels are turning

I'm looking at it, and looking at it, and looking at it...and I can't see anything wrong. And then it strikes me:

He isn't even pedaling.

 

[kwikki]

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.......

A bit like this one then? Slightlly more obvious bunny hops this time.

Re: Re:

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).

I have no doubt that this is legit. He simply bunny-hops over the stairs. You have to add that it's very difficult for sure and that the setting must be perfect: The step size is just right for the bunny-hops. And you need to do it at a relatively low speed. When you're too fast you're not able to hop at the right frequency.

Er, what the guy did on the cross bike is much easier. Heck, even I can do a few steps on my mountain bike !
I can't do any of tricks Martyn Ashton did on his road bike.

In the world of the Hatter, Sagan 'must' have balloons attached to his bike....

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.

 

[Tienus]

I can do steps like that, it is not that difficult if you can bunnyhop. You dont need to peddle as you gain momentum from shifting you body weight. A bit simular to riding whoops or a pumptrack without pedalling. You can even compare it to a child using a swing.

 

[kwikki]

Can you do it with the brakes off?

 

[Tienus]

Yes. With brakes on you wont get momentum, which is why thats much harder as you need to balance yourself without the forward motion.

Re:

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.

How anyone could conclude that a motor is the most plausible explanation for these videos is beyond me.

I wonder what will become of Van Driessche, who does not have the luxury of a silent ban.

 

[Cloxxki]

About the stairs: I see the steps have steps of their own. The bike rolls down a bit. This combines with the push through the cranks and bars can really accelerate a bike even on the flat.

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.

Seems the whole family has a very tenuous understanding of honesty. During the initial tv interview the father told a pack of lies and the pet shop cctv video showed more naughtiness !

Re: Re:

Femke drew the short straw to ever be a person of person reputation, she would always have the thiefs and dopers as direct blood. To get to a decent level in cycling, she drew a longer straw, where money is somehow made available to get bikes and travel sorted. Even motorized.
What will come of her? I hope someone helps her along to bring meaning to her life.

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.
