Wow! This is amazing. Great hunting.
It's about time somebody came up with a "wheelchair" with a little more about it than your standard fair. And being battery powered too, it's a great way to get around.
Obviously not for everybody, as some disabilities will prevent the drive/handling via handle bars, but for a good majority, I'm sure it's something they'd love to drive.
Not an every day option, unless you live in a rural location - where it will be an absolute must. But why should the disabled not have a fun option. I bet there'll be a few calls to increase the top speed a little too, but it's a good start.
It'd be really interesting to hear what a potential user things of this, but for me, it looks a great find.
