Why do bicycles stay up




















Researchers around the world have stated that riding a bike is more of a science than an art. The kinetic energy created is then used to move the bike. The gyroscopic effect is a direct result of the conservation of angular momentum, or spinning motion. In the absence of an external force, the total angular momentum of a system must retain the same strength and orientation.

Answer: When we stop pedalling,the bicycle slows down and gradually stops because of Frictional force. Friction is a type of contact and invisible force which is responsible for stopping an object in motion. It has to move further and that takes longer than with the mass at the bottom, giving you more time to move your hand. The stick with most of the mass at the top tips more slowly, is easier to keep balanced and means that you know how to win a balance-off every time.

There are two theories as to how the bike keeps itself upright. One is the gyroscopic theory, where the spinning wheel provides enough stability to stop the bike from falling. You can try this for yourself if you have a bike handy. So check out the following tips on how to avoid falling from a bicycle. View the discussion thread.

Equally, going downhill on a road bike, a rider needs to get their weight back in order to be stable. The rideable designs floated by Schwab et al include a bicycle which steers from the rear wheel, mentioned in the TED talk above around 14 minutes in.

Papadopoulos asserts that an experienced rider can get the hang of this contraption in a couple of minutes, and he adds that it creates possibilities for building more stable bikes that can help reduce the number of people falling off their bike. Not that this deters Papadopoulos, however. For further reading on the project, head to the Bicycle Dynamics webpage maintained by Prof. Arend Schwab. Nick is a freelance journalist and triathlon coach based in Cornwall, which is perfect because he's a grinder and loves steep inclines.

He started mountain biking in the Italian Alps, where he's from, and then had a stint at downhill. Once he tried road cycling, he was converted, but he's now pondering whether he should get another MTB or a gravel bike. His wife has agreed to try gravel riding, providing they move to Tuscany.
