The Yike Bike looks like a nifty device. Very compact. The only problem I would see for myself is the 100kg (220lb) weight limit. I am slightly below that limit but with my backpack and such I would be over the limit. I wouldn't replace my Segway with this but add this to my collection of transportation devices. Too bad it's sold in Europe for now. Not a cheap device @ $5300usd. Just might have to start saving my pennies for one of these...
