I just finished repairing a Rad2Go that I have been loaned (it was involved in some sort of altercation which bent the front fork) - this gave me a chance to take the bike apart (literally) and take a good hard look, as well as to drive it some more.
Again, I can not stress how much _fun_ driving these bikes is. They're utterly silent (1:1 drive ratio), fast (I've had mine going at least 35.. up hill! ;-)), stable (even my SO, who's never driven any type of cycle except a bicycle, was able to drive it with the most rudimentary of instructions), handle well over bumps (and in seattle, we get plenty of chances to test that). The bike is well designed for the most part, although there are some places where I think they could have used another washer or two ;-) Speed and power is roughly comperable to a Vespa, without the whining drive or the stuttering centrifugal clutch. In fact, this bike is in every way the equal of a Vespa, except that you plug it in. ;-) 20 mile range, I hear that you can drop in the 40A version of the Evercel to double that - 6 gauge wiring throughout, grey andersons on every battery (this might have been overkill, Rad2Go!), space for a onboard charger between the frame rails although there sadly isn't one right now.. full NHST rig - brake lights, turn signals, high/low beams, horn, all the controls in the same place as a normal cycle. The bike even has hydraulic damping on the rear wheel. Standard scooter tires. Seems to be pretty well waterproofed. Ignition was not easily pickable, and with steering column lock just 'hotwiring' it won't let you steal the scooter. Bike is a little heavy at 250+ lbs, but hey, aren't all EVs? It really does feel very stable. Cable-activated drum brake in front, hydraulic disk brake in the back. And sooo much fun to drive.. S.
