Does it have 9 speed control on one side and 3 speed on the other hand control bar?
That's about right, but could change depending on configuration.
What is the maximum speed of this?
Again it depend on yourself. Most people that test ride it can hold 24-30mph on flat ground. Been up to 70mph down hill and 4mph uphill.
Can it handle steep hills ok?
Just like any other bike, it is more work going up hill and it all depends on the gearing you choose. The prototype has been tested across the USA from Portland OR to Washington D.C.
Does it need and rear view mirrors?
It has mirrors and a rear view camera with LCD display.
Are the lights powered by solar panels?
By battery at the moment, 12v LiPo
Can it be pedaled backwards to back up or go in reverse?
There is a reverse yes but that means you have to open the door and use your
hands on the wheels like a wheelchair. The turning radius is so good that you
could usually turn around and never back up.
Does this have those power assist systems?
The first one did not. The second one does have a 250W assist that helps quite a bit.
Are the brakes disc or pads?
How often have you needed new brakes?
It would greatly depend on the type of driving you do and the type of brake pad
you use. Some pads has lasted 2000miles others did 6000miles.
How do you deal with visibility in the rain?
I do use chemicals on the windshield that helps with rain and condensation and but over all it does not bother to much.
How much would one of these go for?
It's hard to say right now for these are only prototypes at the moment but velos usually go between $8000-$15000.
