We bought a couple Rad Minis a couple years ago and there great. i had to modify the seat post on the wifes, she's short to the ground. now it works good for her. the Rad bikes are very hi quality and fold up into a small unit. only down side i have is the weight, they are a little heavy about 70# i think. they have a regulated speed of about 25mph and a range of around 25-30 miles varies on how much you assist by peddling.
