I have a Magnum Metro with rear hub drive. The throttle seems like exactly what you need to get in motion. Spinning the crank is extremely easy because as soon as the bike recognizes the cadence it kicks in the motor. Assuming that you have little power in your legs, you can set the PAS level to make the bike go whatever speed you want. You just turn the crank at a leisurely pace with no effort at all. Unlocked mine will get you to 24mph on a fully charged battery without any work. And about 22mph on a moderately discharged battery. Throttle use only will get you close to 20mpg.
