Honestly, I use vector composition and stuff like that while cycling
Dunno but my mentality is like this, I really really see things from a scientific aspect all the time
I remember once my brother wanted to know how strong is his muscles and how many Newtons does it produce when he rides his bicycle, so he went to buy a device to measure it and I said the following: Well, we can measure the torque produced by your leg in one cycle then substract the frection loss with the street and air using its constants then we can get the energy
he said: **** you :p
