You will love the interesting video, "Most People Don't Know How Bikes Work" by Veritasium - [VIDEO]
Read original comment ↗Indeed. I like this clip where they show bike steering to the left, without its front wheel ever going to the right side of its original path, by only leaning and no countersteering. [VIDEO]
Read original comment ↗Beautiful article. There's a similar neat video, "Most People Don't Know How Bikes Work", where they fix the steering so the handlebars can only be turned left, and people then aren't able to turn left. [VIDEO]
Read original comment ↗Beautifully illustrated and brilliantly explained. Derek Muller (Veritasium) on YouTube has a related video diving into the mechanics of bicycle riding. It shows what happens if you prevent the rider from performing the countersteer before leaning into a turn [1]. [1]: [VIDEO]
Read original comment ↗Veritasium did a video where they stopped him from counter-steering and couldn't steer anymore. [VIDEO] He might be wrong, and just didn't know enough, but he is usually researching his videos very well and I would be surprised for him to be wrong about this.
Read original comment ↗Here's a good video showing how a bike actually works, and the relation between steering and leaning: [VIDEO]
Read original comment ↗> You only think you understand how a bicycle works, until you learn to ride one. I realize this is just for motivation in a subtitle, but people generally don't grasp how bicycles work, even after having ridden one. Veritasium has a quite good video on the subject: [VIDEO]
Read original comment ↗As someone who can ride aggressively without handlebars, you counter steer even without touching the bars. [VIDEO]
