I'm surprised at the HandyBike not being more popular too, Royalflash.
Even "Razor," the original scooter folks, have taken a shot at building a scooter-bike:

It's a toss-up for me which would be easier to get - the Razor seems solely marketed in Australia and the Pacific Rim, despite Razor scooters being all over here. HandyBike seems more targeted at Europe.
Thanks for the eBay link - I hadn't been able to turn any HandyBikes up. (I have relatives in Germany so they may be able to help sort out the shipping if I go that route)
