You can get a similar demo if you're too cheap to change your front tire and it gets triangle-shaped. Handling will suddenly change in an unsettling way once the bike rolls onto the un-round part of the tire. It feels like you're sliding and gonna crash, but you can sort of get used to it. I don't recommend it though.

If you're not used to using the front brake, and you get into a situation where you have to emergency brake... you'll probably just grab a fistful of brake and instantly trigger your ABS, which increases your brake distance. And if your bike doesn't have ABS your front wheel will lock and slide. That's because you don't have the muscle memory of how to brake correctly. Even when you have to brake as hard as possible, instantly applying full brake power is not correct, you have to apply less force at first and then quickly increase.

We bought my SOs bike with a flat middle rear tire. I mean literally 3-4 inches wide of nearly flat tire. They only rode it on the highway so I guess it just never saw any action. It was odd having the bike "lift" up on lean initiation. Once we got the new one on, it felt like somebody took the training wheels off haha. Before, you almost had to force it on the side of the tire.
@user-ju7dx8mu6d
7 ай бұрын
I had to add a few more comments. The tire (or as I like to call them truncated variable slant bicone)/ cone discussion is great and once you start to think of tires this way you begin to understand the intricacies of tire design. However, the discussion of counter steer is still weak. To truly understand the countersteer/lean duality, hold a rapidly spinning bicycle wheel with one side of the axle in each hand. Try to turn the wheel about the Y axis as if making a slow turn to the right. It will lean so hard to the left that it could rip out of your hands if it is spinning fast enough. Now try to lean the wheel to the left. It will turn to the right duplicating the motion you made previously. The lean and the twist are powerfully linked by the gyroscopic effect. When you try to accelerate the wheel around the Y axis you are acting against the huge momentum of the spinning wheel which creates a large slanting force. If you try to lean the wheel while preventing the twist, you will have a very hard time indeed. That is why you can turn a bike by leaning if you are riding no hands. When we turn by leaning we either instinctively do not prevent the twist or do not have the means to (hands free). We counter steer in unison with the lean because we have to. If you try to lean steer while tighly holding the handle bars, your grip is fighting your lean. So does it make a difference if you think you are initiating a turn by leaning or counter steering? I say it does. To shift your center of gravity is a big and slow motion which requires you to shift your body weight. Counter steering is short and fast and it uses the rotational momentum of the front wheel to lean both you and the bike with great force. For every day steering the difference is not important but for many rapid changes in direction and/or high acceleration turns, countersteering is faster, more easily controlled and ultimately less tiring because it generally takes less energy to apply a turn initiating force in your arms than it does to shift your weight. Love to see a video with you turning a spinning bicycle wheel in your hands.

When actually riding the bike this is always the case! Never do anything else than coutnersteer. Sweden has a somewhat strange, but good anyway, part in the technical step of the final driving test for motorcycle licenses. It's called "lågfartsbana", a walking pace (chance of failure increases if you surpas ~7km/h) slalom with rather tight tolerances (hit the steer stops in almost every turn on my Street Triple) and 2 stops. The trick is of course to keep the bike upright as not enough centrifugal force is generated at that speed, and try to counter every degree of lean with your body. That course doesn't focus on countersteering.

Done it for 50 years without knowing. Then at trackdays herd about countersteering. Active countersteering instead of just doing it intuitively makes your riding so much better, decreasing lap times. Also easier to cope with dangerous traffic situations. Though not always possible. Friend who had raced at the Isle of Man several times where the northern part is very bumpy explained it as "going 120+ Mph, front wheel is mostly in the air, so you have to steer into the curves with your knees."

FWIW, all balancing modes of transport use countersteering to initiate a turn. Skiing, snowboarding, running, etc require that you outtrack to initiate a quick turn. Anyone who's ever been running and got trapped on the edge of the sidewalk or a curb unable to turn away without putting their foot in the grass or on the street will understand this one. We even do it at walking speed, but it's less obvious because our feet are naturally a little bit to one side or the other of our CG, so an outtrack to the right just means putting your right foot down not exactly under your CG, causing you to lean to the left slightly to start a left turn. For skiing and snowboarding it's a little tricky to outtrack while going perfectly straight, which is why we tend to carve out large continuous turns with the skis or board just flat enough to cause a little bit of side slip. If we're in a large radius left turn, we initiate an outtrack further to the left, by setting the edge to decrease the turn radius. The board or skis go left quicker (an outtrack to the left in a slow left turn) causing our CG to cross over to the right side, and initiating a right lean, and thus the right turn. Understanding that all turning requires counter steering, really helped me learn how to ride a snowboard.

@@kenthartfield3237 You're entitled to your opinion but the physics is clear, and entirely testable. They're both still balancing activities. Try this easy one yourself. Establish a brisk walk right on the right edge of a sidewalk (for safety find some place with grass at same level on both sides) and then at some point try to initiate a quick 90 degree turn to the left. You may be able to make a slow turn by just shifting your upper body weight over the course of a couple steps (much like riding a bicycle without hands), but if you want to change directions quickly you'll find that you have to step off the right edge of the sidewalk (outtrack/countersteer) to do so. Now try going straight, then zig zag at fast walk, then jog, then running pace. Notice that subconsciously (until now) you always wait until you can plant your right foot wide to initiate a hard left, and vise versa. As for skiing. If you're going down the hill in a wide stance you may not think you're countsteering because your weight is on both skis, but consider that to initiate a left turn you have to put more weight on the right ski. You're shifting your contact point to the right below your CG, to turn left, and vise versa. But what I was talking about is the way people ski when they go fast on packed/goomed snow, feet mostly together carving big turns. If I'm carving a left turn and need to switch quickly to the right, I can either force my left foot out further left and put my weight there (still outtracking as above) *or* I can roll up onto my skis left edges which (due to their shape and our rearward position on the ski) causes the skis to turn more sharply to the left which throws my body over the skis to the right. Visually we may perceive it as the skis cutting left and right while body just goes down the fall line, but you can't make that transition quickly without countersteering. To be clear, I do ski, and I transition this way. What I do looks no differently to how anyone else skis, I just am aware of *how* I'm doing it, just like someone who knew how to ride a bike and now consciously countersteers.

You are just spouting nonsense. Nothing you described is countersteering. Both skiing and walking are analogous to a double tracked vehicle which does not countersteer to initiate a turn. It may be that you like to turn in the wrong direction before you turn in the right direction while walking or skiing but it is neither required nor helpful to making a turn. Have you wondered why no book or video on skiing has ever mentioned countersteering? Have you ever wondered why no book or youtube video has ever discussed countersteering in the act of walking? It's because it doesn't apply. So tell me, Is ignorance actually bliss? Inquiring minds want to know.@@daemn42

@@kenthartfield3237 My assertion is testable and falsifiable but you didn't bother to take the 5 minutes to step outside and test it yourself. Just because people don't realize they're doing something doesn't mean it's not still happening. The idea of "countersteering" didn't exist for about a century yet people were still doing it while riding bicycles first and then motorcycles every day. Then people would assert "it only applies at high speeds" and that myth persisted for almost another half century, but is easily disproven. As for "multi track vehicles" the wiki article for countersteering points out "Free-leaning multi-track vehicles must be balanced by countersteering before turning." For skiing to not be free leaning you would have to maintain a fixed super wide stance where you don't lean your body, especially leaning inside your inside ski. And walking is 100% a balancing activity. There's no way to walk while keeping both feet in contact with the ground all the time.

In driving school my instructor (who was pretty nice otherwise ) told me to lean in the corners. It did not work the expected way. I have driven bicycles for years before that so I am naturally counter steering, but at that time I didn’t know it exists. And on the motorbike it did not naturally occur to me. It took me a while and at some point I was also counter steering harder so I could lean more. I think my driving instructor tried to keep it simple and most people naturally counter steer when they are told to lean, but if he told me about counter steering before it would have worked better for sure.

Yes. Which is why putting weight on the inside handlebar of a turn WILL actually make the bike turn. It's pushing the steering not offsetting weight from the center. Unfortunately Ryan equated that with "weighting the bike" and said it wouldn't make it turn. He also left off the part about the geometry of the steering and forks being the thing that is always trying to right the bike (it's not just rotational inertial, you can see this effect in a riderless bicycle going walking pace) which is why a constant pressure is required. Ease that pressure off the inside handlebar mid corner and the bike will want to stand back up.

When you added the extra handlebar, the bike was throttle locked. Being in maintenance throttle is an important detail. As long as the bike is in maintenance throttle, the rake and trail cause the bike to steer itself to be stable. And with no bar input, the bike only wants to go straight (or straighter). In order to make the bike lean quickly, you need to make a bar input. And on top of that, in order to maintain a relatively deep lean angle, you must maintain countertorque on the bars. Deeper the angle, the more force must be applied to maintain that angle. If you were to completely let go, the bike would stand back up a bit. A lot of riders are unaware of the countertorque needed to keep the bike leaned while the bike is in that stable condition, in maintenance throttle. They may do it unconsciously at lesser angles but they start to get sketched out at deeper lean angles when this force gets stronger. At deeper lean angles, riders get scared of losing traction, so it's counterintuitive to apply MORE force on the bars, even though this is just a normal part of steering. But if you are lightly dragging brake to decelerate enough, the bike destabilizes and stops steering itself. And the bike will slowly drop deeper into lean without bar input. This is a slow way to make a bike lean deeper, and it makes the bike respond more slowly to bar inputs made on top of it. But since you no longer have to maintain countertorque to the bars to keep the bike from standing up, a lot of riders falsely believe that it's the proper way to take a corner, and they somewhat laughably think they're doing advanced trail braking.

Keith Code makes a good point about "body steering", although it is kind of brief in his video and skipped over here. You can steer by putting a knee in the tank and leaning off to the inside, this does work, albeit inefficiently. But the reason it works isn't the reason the "body steering" proponents think, it is because by pulling in with a knee on the opposite side of the tank you are doing the exact same motion of bending the bike like a hinge at the steering neck that you would do much more efficiently with the bars. So either pushing forward on the inside bar, or pulling in on the outside near the steering neck causes the front wheel to move the exact same way and countersteer, it is just less efficient than using the bars.

An effect of conical profile of the tire would be to generate a twisting force, turning the tire itself until a given radius is meet, but no generating a cornering force on the bike.

When I was a toddler, I had a toy bike with square edged wheels. I would get furious when I couldn't balance because my toddler brain thought flat wheels would be easier to ride and learn on.

Nice to see the Dunlop Mutants on here again. I looked into them based on Ryan's recommendation and bought them based around everything I'd seen. Turned out to be a great little tire.

Thank you! I workt at university and last week, I tried to convince professors about nonpossibility to turn right without countersteer left at first.

Excellent demonstrations of a time old argument. The USAF was teaching countersteering way back in the '70s.

Twist of the Wrist is great book by Keith Codes. Sure did teach 18 year old me how rip in the Ozark’s back in 04. I studied that book every night after work so I could go rip with my Dad on Saturday and Sundays.

To any of you guys looking for tires for your sport bike and are undecided, get the rosso 4 corsa. It is the best tire made right now and gives you much more confidence putting it on its side. 50,000 miles on my S1K and MANY different tires, the rosso 4 stands at the top of the mountain.

back in the day I somehow got some flat MtB tire on my bike & I was shocked at how well the cornered on loose over hardpack. The shape edge would dig in the soft/loose forcing up a ties widths berm of soft banking.

Interesting. At low speeds I've always turned the handlebar like a steering wheel on a car. The slight opposite movement to initiate a low-speed turn I never noticed. In fact I'll have to check that motion out myself in a parking lot this spring.

7:13 - I have always wondered why the is no profile specification or standard so tires can be compared? As this impacts the handling, it should have and not only rely on feel. 🤓

the curviture of wheels impacting the turning radius is the reason train wheels are shaped like cones, it self centers on the track and allows for turning corners without having pivoting axles

It is the same on a push bike as well. The amount you steer in the opposite direction is extremely minimal.

Sorry @F9, but you are forgetting the gyroscopic precession which is the reason why the front wheel turns when you lean. In a nutshell, a force applied to a rotating body will act 90deg later. All the rest is great. Thanks for you super videos!

Where the hell did you find the cooool RV. When I worked in a Suzuki shop back in the 80's we had one for a shop runabout, I built a sidecar on it to carry parts etc in. It had a front on sidecar like a tilted back dozer blade and over about 25mph it stuck to the road like glue, even when turning left. Very cool.

You're correct about doing it subconsciously and learning it as a kid, which is why balance bikes are 100% the best and only way a kid should learn how to ride a bike. Learning to ride with training wheels/ 'stablizers' is the worse possible way to learn how to ride a bike as it doesnt training your brain for how an actual bike works.

So my friend just inherited his moms trike. A custom dyna from the 90s w a corvette back end. It’s so weird to ride. No leaning. No counter steering. It feels like it’s gonna tip every time you push the bars.

Great video, except for the fact that the third point kind of disproves itself. When you showed an example of the bike leaning over at 5:48, the center of gravity remained above the tyres, as you counter leaned to compensate for the angle of the bike. The angle of the tyres bares no impace on the ability to turn. By leaning over, moving the center of gravity from above the tyres, there must be a force parallel with the ground in the direction of the lean that prevents the bike from falling over. Haing flat tyres means that the resultant force from the ground is always trying to right the bike, hence additional force is reuired to keep the bike from standing back up. Rounded tyres ensure that this resultant force is perpendicular to the ground, and therefore does not act to re right the bike, allowing smooth turns. The tyres do not act as a cone as their contact patch is so small in crosswise length that it can't generate the turning force required. A cone spins in a circle becuse one end travels much further as its diameter is bigger than the other. The difference in length of the contact patch is so small on tyres this will constitute a tiny effect. If this affect were true then performing the above experonment at 5:48 with rounded tyres would cause the bike to turn, however we know this not to be true.
