A TDay puzzler to ponder....
Let's suppose I have a bike with a flipflop rear wheelfixed on one side, free on the otherwith a single chainring up front. The fixed sprocket and freewheel are both identically sized; that is, they have the same number of teeth (and neither one is missing teeth ).
On a windless day, I climb a hill, from base to summit, with the bike in freewheel mode. After walking the bike back down to the base of the hilland taking enough time to recover completelyI flip the wheel over. I then climb the same hill, from base to summit, in fixedgear mode. A glance at the bike computer shows both rides are done with the same average speed.
My question, then, is as follows....
Assuming my strength remains constant, which rideif anyrequires less energy to reach the summit?
