I'm well aware of this, that is why I mentioned GPS-tracked bikes. If you actually READ the source link you posted it stated EXACTLY why this one firm failed...

"Unlike rivals, the firm did not put GPS systems on its bikes and by the time it realised the technology was necessary, money had run out."

What's sad is Biki will be in the next sucker to go belly up as they don't use GPS. The bums will just go get a $5 VISA gift card at a convenience store and never return the bike to the station and Biki will never return our $2-million they took from us.
