Ordinary people ride ordinary bicycles with no speed change function, and the speed is 12-20km, so pedaling in the air 1 hour is about 14-23km, because pedaling in the air is a little easier than riding normally.

Air pedaling is a kind of fitness exercise. Steps: Lie on your back on the yoga mat with your arms close to the ground and your legs at an angle of 30 with the ground; Your legs bend and stretch alternately, and you feel like you are pedaling your bike backwards. Move as slowly as possible and don't kick hard; The back waist is always close to the ground.
