Bicycle Rolling Resistance Calculator. Just curiosity as i frequently bike the same route and wanted to see how much i was burning. 42 5 kg 94 lbs rr 80 psi 5 5 bar rolling resistance at 60 psi 4 1 bars single tire speed.
The force resisting the motion of the bicycle f total consists of the sum of rolling friction f roll aerodynamic drag f wind the force needed to accelerate f accel the upward slope resistance f slope bearing friction resistance and loss due to the drivetrain efficiency factor η greek letter eta. Rolling resistance at 100 psi 6 9 bars single tire speed. Unfortunately lower tyre pressure also.
29 kmh 18 mph load.
Rolling resistance will be reduced and the bike will run smoothly with plenty of propulsion. Unlike the other quantities acceleration and upward slope resistance can also be negative. All rolling resistance rr figures shown below are for a 50kg load on the rough surface drum. 42 5 kg 94 lbs rr 80 psi 5 5 bar rolling resistance at 60 psi 4 1 bars single tire speed.
