Yikebike: How much: €3700~ ($5400) | How far: 9-10 km (5.5 miles) | How fast: 20 kph (12 mph)

For comparison...

Segway: How much: $2-7000? | How far: 38km (24 miles) | How fast: 20 kph (12 mph)

Another comparison:

My shitty commuting bike: 50€ | Range: unlimited | Top speed: a bit more than 30kph depending on how fast you can spin

I agree. But to be fair, you should compare it to a Brompton folding bike (that have an excellent design btw, the parts fit perfectly). http://www.brompton.co.uk/

I'm sure it compares favourably to the Yike, but the range on your commuting bike is not unlimited. How far can you ride before you have to stop and eat?

I bet I can go farther on my bike before stopping and eating than the Yike can go without stopping and recharging.

I can eat on the bike, actually. I did 210 km one day, a number of years ago, and only really stopped once (I had plenty of food that I ate as I went), but that wasn't with the city bike, for sure. Even the nice bike costs half of what this thing does, though.

Bicycles, on reasonable terrain (i.e. roads of some kind, or rideable trails) are the most efficient form of human transportation, in terms of energy / km.
