BTW I love how the pictures being used are illustrating clearly the point that the tires are not pointed into the turn.

How can I tell? Look at the rider's head. The rider is looking into the turn. Does the wheel line up with the rider's head? The answer is clearly no in the pictures below:

You can't be serious. The first picture clearly has the front wheel turned in the direction of the turn. Left turn, wheel is left of center.

I did this for a bit and it blew my mind!!! just not quite what i expected.

anyone reading this thread, just do this and you'll figure it out.

Your head does not track, exactly, the turn of the handlebars. If it does you are really not turning correctly. So you can't follow that as a reference for how the bike is tracking the turn. Look at all of those pictures again. In each one the front wheel is towards the inside of the center line of the bike. None of them where the bike is at the apex of the turn has the wheel on the opposite side of the center line. Since the rear wheel can't steer, use it for determining where the center line is.

When this reaches the level of a high school paper, much less a PhD dissertation, then we can say that Wikipedia isn't credible source. However the discussion isn't at that level, now is it?

You have been shown numerous examples of bicycle wheels turn into the corner of a curve. You have been shown explanations for the centripetal force acting on a bicycle wheel. You asked, and I explained, how you can ride a bike while leaned in a straight line. In the face of all that you still contend...as do others...that the wheel of a bicycle is pointed away from the turn during cornering.

It is up to you, now, to show how centripetal force works opposite the direction of a turn. I'd like illustration, pictures, etc. of a bicycle that clearly the wheel to the opposite side of the centerline of the bicycle. The picture also has to be of a bicycle clearly in control without the rear wheel sliding to the outside of the curve.

I look forward to your proving that centripetal motion and centripetal force don't work the way that it's been taught in physics classes for eons.

Edit: Camber thrust? The friction of the tire pulling the bicycle around the corner? How is that any different from what I have described? It doesn't appear to me to say anything about the bicycle being steered in a direction opposite to the direction of travel. It simply makes the bike not go off in a tangent to the curve. In other words, it still centripetal force acting on the tire. The curvature of the tire helps pull the bicycle around the corner. So another thing you need to show. How does this make you steer opposite the direction of the curve? Or is this just a red herring?

Here's a little light reading. Look at page 13 in particular. First paragraph. "...To stay balanced, the handlebar's angle of rotation will deviate from zero depending on the radius of the curve and the velocity [of the vehicle]." With an illustration that clearly shows the handlebar's deviation from zero in the direction of the curve. Just like the computer animation I linked to.

Wiki still rocks - there are references and terms; it is a starting point.

I'm sorry, did someone cite their thesis in this thread? ...must'a missed it.

From there, I go out and see (uhm, saw) for myself, starting out with walking around the driveway with one of my bikes. Tonight is the local crit, where I test my OWN conclusions - from there, that's it, for me.

I'm resurrecting this... try this for a test.

Put both hands right next to your stem (one on each side of course). Ride. See which side you push on to go in each direction. You'll find you'll push forward on your right side to go right. Push forward on the left side and you'll go left. Now do that on a descent around a curve. The more you push right, the sharper you will turn to the right. (and vice-versa on the left)

^^^^^

Exactly. With the hands in the hooks, you'll find that turning to the right can be done with only the right hand, in a open position, where it can't be used to pull on the bars. There is never a need to pull on the bars or push with the left hand. Just vary the countersteering pressure and the bike will go from leaned over and turning sharply, or back to upright if no pressure is applied. Use the left hand for left hand turns.

seeing the pictures above, i made a conscious effort today to turn the head and also the shoulders into the turn on a particular curve where before if i didn't slow down i would swing wide into the middle of the road. i also leaned my body in line with the tilt of the bike rather than staying more upright than the bike.

result was whooooooshhhhh. very tight turn at higher than normal speed.

^^^^

Leaning with the bike should be the natural thing to do. Leaning away from the turn makes no sense. The bike isn't going to fall over. I still have to emphasize countersteering. It takes little effort on a bicycle compared to a motorcycle, but the principle is still the same. Learn to countsteer and you won't swing wide. If you do, at least you then know how to correct the problem.

I still say that most cyclists would benefit greatly from an introductory motorcycle course. They don't cost that much.
