The theory about cycling is confusing.(Almost they ignore the basical theory of physics.)
\nI think that the principle of cycling are on the above picture.<\/p>\n

The mass of a rider are supported by 3 positions. Wheel, saddle,and pedal.
\nAnd the mass supported by pedals produces the power wheeling bicycle.
\nAnd its energy are equal to the elastic potential energy.
\nThen we can calculate it by the next formula,<\/p>\n

Work (J)=mass(kg) \u2022 height(m) \u2022 G(N\/kg)<\/p>\n

And if you want to run a bicycle faster, you should increase the power (work in a second).
\nThe formula about power is below.<\/p>\n

Power (W)=Mp(kg) \u2022 0.34(m) \u2022\u00a02 \u2022 G(N\/kg) \u2022 n (\/sec)<\/p>\n","protected":false},"excerpt":{"rendered":"
