Let's say you've got two electric bicycles both powered by identical 250W motors. Both are fixed gear. Both weigh about the same and have riders of the same weight. Both riders contribute no force to pedalling - all the work is done by the motors. The only difference is the first bike has 20" wheels, the second has 26" wheels. Both bikes get up to 25kph on the flat, then they are faced with a long steep hill.
Do they perform differently going up the hill, and if so, why. Would one get up the hill more easily? Would one be faster than the other?
Looking forward to your answers.
