Not everyone can pedal as fast as the motor takes them. 4 or 5mph is a good amount of extra speed for a bicycle. Besides top speed, I think the NOS would be good for added acceleration anyway.
Say you are doing 20-25mph and need to cross an empty road to get into an upcoming turning lane, but cars are coming up from behind in the distance.... You want to cross the road as quickly as possible to not get hit by cars. This is one example of many that NOS would benefit a bicycle.
