can anyone tell me the method by which the aspect ratio for the motorcycle tire can be decided given that load capacity of bike is known.

that's what I'm asking what am i doing wrong?

am i doing it right?

no i don't know the fish and rope method

μMg

the friction which will oppose the motion of wheel

i'm also interested in knowing the friction force on the rear wheel.

no please tell

im asking for starting torque because it want to know the reduction ratio i have to provide coz my motor is providing me a peak torque of 20 nm

thanks everyone for replying... my problem is...my bike is standing with a load mentioned now i want my bike to move on the road,so i think static resistance will come into play.i'm confused about how much friction force does the motor have to overcome when it will rotate the rear wheel.

hey everyone I'm interested in finding the starting torque of a bike weighing 120 kg with a load of 150 kg and having the tire specification of 120/70 R17. starting torque means the amount of torque i need to provide to wheel in order to start moving the bike from rest. power source is a 4kw motor.

hey azfireball, how to proceed if i want to calculate the starting torque required for a bike weighing 120 kg and a load of 150kg with tyre specification of 120/70 r12.
