What makes a bike stay upright?
Bicycles are inherently stable because of their geometry. The geometry causes the bicycle to always turn into the direction it begins to lean, which keeps it upright. The reason is best illustrated through a concept known as counter-steering. Counter steering is how all two wheel vehicles turn.

20km/h (12.4 mph) – many “occasional” cyclists ride around this speed. 25km/h (15.5 mph) – most commuters. 30km/h (18.6 mph) – fast commuters, slower roadies.
Are bicycles efficient?
The bicycle is a tremendously efficient means of transportation. In fact cycling is more efficient than any other method of travel–including walking! The one billion bicycles in the world are a testament to its effectiveness. The engine for this efficient mode of transport is the human body.
What force keeps a bicycle wheel from flying off?
Another idea you should know about in order to understand a gyroscope is centripetal force. This is a force that pulls on an object that is spinning around another object and keeps it from flying off in a straight line.
What muscles do bicycles work?
The main muscles at work in cycling are the quadriceps and hamstrings in the upper leg, and the gastrocnemius and soleus in the calf. These muscles contract in a sequence that creates the pedaling action. The quadriceps and hamstrings do most of the work when you ride a bicycle.
