The Ford Th!nk and the LaFree are electric assisted bikes (pedelecs) and are not moped like. There is no throttle, and they do not propel you if you don't pedel. You have to put in the some pedaling force, and they are designed to disengage the clutch after 20mph and then you're on your own. To be honest, it feels like a supercharged bike. If you pedal softly, you will get very little response. if you slam down hard on the pedals it will assist in really torquing down the rear wheel. You will most definitely be getting exercise on one of these! The positives are for the same amount of exercise you go 4 times the distance so it's a fair trade -- exercise that makes a commute possible.
