Part of me wonders why only 6 years. It doesn't seem like someone who would do this has much respect for the sport.

Because six years for a 19 year old cyclist is essentially a lifetime ban. There is little to no chance of her returning to the sport after that kind of extended absence.

It makes me wonder if the engines would be this sophisticated if they weren't for cheating?

Even rather casual cyclists will want something as light as possible and the in-frame hub drive arrangement has nice aesthetics.

And less likely to be stolen if parked. Though not sure if anyone would park a bike with such an engine.

I don't see it in the article but I heard it recently so I guess I'll share.

Lance Armstrong was on the Joe Rogan Experience and discussed doping within the sport. He said at one point in time, people would thread fishing line through a wine cork. They'd tie the line to the tail of a car and stick the cork in their mouth. As the car starts moving, the cork pulls against your teeth giving you just enough pull.

Most probably not. It's pretty clear in the FranceTV video (It's in French though) in the section starting at 14:40 https://youtu.be/e0s2yo6ws9U?t=884

Starting at 17:00, he describes an electro-magnetic wheel, Lipos inside the tube, magnets all around the wheel, remote controlled by a wristwatch. Priced 50K€ at 200K€, can't possibly be used for casual cycling.

Yes but casual cyclists will not pay €2499 for the pleasure of doing so

Earlier quoted context omitted.

These motors work by directly coupling to the pedal shaft in the bottom bracket. It's hard to tell but it seems pretty clear to me that the pedals on Hesjedal's bike are not turning when it lands. The angular momentum is just from the back wheel which is still spinning.

Probably a different type of motor. If you watch the video the back wheel slides along sideways for a while. This would stop all usual motion of the wheel and there is no way that it would maintain sufficient power to move the bike as it does even if there was some residual rotation.

What kind of motor then? Wheel hub motors are sufficiently large that you could recognize one from meters away. There are only so many places to put a motor on a bicycle and at some point you have to come up with an explanation for what happened that doesn't involve a motor.

It's enough to destroy her career which is all they really needed to do.

To do it you have to have no respect at all. Sure EPO is awful, but an extra 200 watts for no extra work is a different level.

That's got to be the most French way of cheating I've ever heard.

If the motor was installed by a family friend, why would that person need to conceal the switch?

And there was the race at the Koppenberg where she smashed everyone up the hill setting the Strava QOM, then lost lots of positions on the descents and technical parts, right until the next lap of the hill where she smashed up it again. Rinse repeat. It's not surprising the ban starts at a date earlier than when she was caught, the UCI strongly believe she was using the motor earlier.

I'm not familiar with that race specifically, but it's not unheard of for a young rider to have massive strength, but little technical skill. The ability to descent and maneuver technically only comes with years in the saddle.
