On a bike, even at speed you can initiate a turn by simply leaning on the side.

[marodox]

The front wheel still kicks out in the opposite direction and counter steers for you due to the natural stabilizing properties of the bike

[jstanley]

You can, but it's not very effective.

This 3 minute video explains how important counter-steering is with some actual experiments: https://www.youtube.com/watch?v=JWuTcJcqAng

Easiest way to try/prove this is ride without holding handlebars. You can turn corners easily.

Limits (compared to regular turning) are your lowest speed is higher (where you'd lose balance without holding handlebars) and the fact your center of gravity and stability are messed up (can't turn as tightly). And self preservation of course.

See 2:33 in this video: https://www.youtube.com/watch?v=JWuTcJcqAng&t=2m33s

Turning by leaning only works at all because when you lean it causes the handlebars to countersteer.

To prove it, lock your handlebars so that they can only point straight forwards, and then see how easy it is to steer. It's practically impossible.

It's impossible to start going straight even. The point was that leaning will initiate the turn (no limits on method).

That's totaly not my experience.

With all due respect, your experience, internet denizen, is overruled by reported experiment. See the video linked above.

[baud147258]

It's experience vs reported experiment, I don't see how one is can overrule the other. I'll check the video later.

[komali2]

You're right, "overrule" is probably too strong a term.

I meant it more as a comparison between anecdotal evidence vs research evidence. I.e., someone saying "I've never seen a fire, I'm not sure why we need to bother with fire drills."

Maybe better would be "why bother getting vaccinations, I've never seen a bacteria in my life."

[baud147258]

I've done a lot of riding without holding handlebars, so that's how I learned this.

Another limits is that you've got a delay to reach the brakes, which can make it dangerous for others in addition to yourself. And I agree that having your center of gravity moved up really mess up your stability.

[maskros]

Only if you've got a stupid racing bike with only hand brakes. Coaster/foot/back-pedal brakes are standard issue around these parts, and I wouldn't ever want to ride a bike without one.

[JoeAltmaier]

Depends on how you ride. An adult in the US, you're on a road bike bent over the bars and going 15-20mph. Hands on the brakes at all times. I do a ride every summer with 20,000 like-minded people and if you see even one bike with coaster brakes all week its unusual.

[maskros]

Europe is full of city bikes with coaster brakes. Everybody here has a bike, not just the hard-core bikers.

[baud147258]

I've rarely seen coaster brakes, especially among the non hard-core bikers here in Paris.

[JoeAltmaier]

I don't know if all 20,000 people are hard-core. Its just that road bikes are very, very common. Kids bikes might have coaster breaks, sure. But hardly anybody over 15 has one.

[perl4ever]

Brakes on rear wheels only are relatively ineffective, so I don't understand why you would prefer them. Unless there is such a thing as a front wheel pedal brake, which I have never heard of.

[maaaats]

Why is hand brakes stupid? Much better control/modulation, especially with hydraulic disc brakes.

[maskros]

Rim brakes either grip too hard or not enough, and sometimes don't work very well in rain, and need regular maintenance and replacement. Coaster brake supplemented by hand brakes for emergency stops just feels safer and more in control in traffic situations.

[komali2]

Unless your feet are on the pedals wrong...

Or cheap basic road bike.
