How to calculate torque req. to move a bicycle

How to calculate torque required to start a bicycle:
give the coefficient of friction.
You want to calculate starting torque that means the torque to overcome static friction bw wheel and ground.
static friction(forcew) = u(coeff of friction) x N (weight normal reaction)
torque at wheels=forcew x radius of wheel.
divide this by 2(gear ratio)
u'll get the torque applied by rider to accelerate the bike from 0.

gear ratio=front sprocket/rear sprocket
