   In an ideal situation with no energy loss the force is the same.   
      
   Even with out any air resistance there is a small energy loss in the   
   bike that is more than 10 times bigger for B than for A but not much.   
      
   The biggest difference is that B most work his body 10 times as fast as A.   
      
   So you can say you don't need a stronger bike to go faster uphill,   
   but you need a stronger/faster body to push the pedal faster.
