My back wheel will no longer spin freely - Bicycles Stack Exchange.

Take the brake band off, then put it back on with the tension very loose. Slowly increase the tension until you can feel the wheel pulling the yarn into the orifice. You might also want to try putting your drive band onto a larger whorl, which causes twist to enter the fiber more slowly.. The gyroscopic effect of the wheels by itself is likely not that strong, but the gyroscopic effect on steering works with the angle/rake of the fork to turn the tire in the direction of the "fall" and provide even more self-stabilization.

Truing Wheels - Sheldon Brown.

I took the wheel off to take a better look and noticed a ton of metal shavings in the wheel well of the frame as the wheel seems to have been eating away at the gear derailleur metal plate slotted into the frame. The bolt going through the wheel has 2 flat sides and the wheel well doesn't seem to have those matching ones anymore?. The first step in repairing a wheel is to check the condition of the rim itself. If the rim sidewall has a blip (bulge), no amount of spoke adjustment will help the problem. A rim brake will catch on the spread-out part of the rim. This will cause dangerously uneven braking, and possibly may even cause the wheel to lock up under hard braking.

A good way to do it is by pressing it closed with your palm. This lets you put your fingers behind the frame to help squeeze the lever to close it (the lever should be tight enough to leave its impression in the palm of your hand). If you can only close the lever part way, open it, unscrew the adjustment slightly and try again.

Why does a bicycle remain balanced when riding, and fall when... - Quora.

When I power it on and lift it off the ground both wheels do spin in unison for a short time and then they stop after about 3 seconds. Looks like it's fixed right? Wrong. When I put it back down on the ground only the right wheel moves. I read about turning it upside down and powering it on (that didn't work)..

How a bike's wheels and crankshaft influence how the machine handles.... The two numbers that describe motorcycle steering itself are the rake... these bikes' wheels spin at over 3,000 rpm. Answer (1 of 142): It is a common misconception that gyroscopic effects are responsible for the stability of a riding bicycle i.e. the bicycle balances itself in a similar way to a spinning top balancing itself. While this may be intuitive to think so, it actually is not true. Gyroscopic precessi.

Stand at the front of the bike and locate the forward-facing pop-pin just below the handlebars. Use one hand to pull it out a little into the unlocked position and use your other hand to lift the bars up or push them down. Let go of the knob or push it back in once you've adjusted the bars to the right height. [15]. Up until a few decades ago, scientists thought a bicycle is self-balancing when in motion because of gyroscopic effects and caster effects alone. "Gyroscopic effect" means that a spinning wheel tends to stay aligned in its original direction..
