I saw the video below on Facebook. It was a from a corner at the World Cup today in Italy of Wout Van Aert running a technical section of the race. The video is short and it initially looks like the his rear wheel accelerates on its own when it leaves the ground.
Obviously, the left pedal hits the ground and the crank rotates 1/4 of a revolution. Is that enough to accelerate the wheel so quickly?
There have been something like 70000 views at the Facebook page. Lots of the comments are in Spanish, but there are over 400 of them. Plus, 530 people have shared the post.
To me, it doesn’t look like it is an issue, but if you don’t pay attention, or don’t watch the video more than once, it is easy to think the bike has a motor. The way the dude rides many times, you’d think he has a motor.
You decide for yourself.
