CONSIDER THAT THERE IS NO SLIDING ANY WHERE


 



CASE 1 :- WHEN THE REAL WHEEL BREAKES ARE APPLIED
CASE2 :- WHEN THE FRONT WHEEL BREAKS ARE APPLIED
CASE 3:- WHEN BOTH THE BREAKES ARE APPLIED                                   SIMULTANEOUSLY 


CASE 4:- WHEN THE PEDAL IS ACCELERATING IT

In all the above cases the friction acts in forward direction. In the three cases of application of breaks the breaks tries to stop bicycle by applying force in backward direction Hence friction acts in forward direction. And in the case of acceleration the tires pushes the earth in backward direction to move forward i.e. force is applied in backward direction and friction acts in forward direction.

but the answer is 

case 1        frction will be back ward on rear wheel and forwanrd on front wheel

case 2       friction will be forward on rear wheel and backward on front wheel

case 3     friction will be back wards on both wheels

 case 4    friction will be forward on rear wheel and backward on front wheel
