At my previous agency we built the website for a competitor to a bike like this. They gave us one to keep at the office so I have a little experience with it.

The bike in this article has all the same problems as the one we had.

It's waaaaaay too heavy. You can't really peddle it, not for long anyway, it's virtually impossible. It's only a matter of time before the battery runs out on you and you find yourself stuck.

You can't get it around. The one we had took several people to move up and down things. This is a pretty big issue when you're living in a London apartment (their target market).

Then there's the segway effect. Was it PG who said that you can't ride one without looking like a smug twat? The first time my boss took it out some guys in a white van slowed down to yell "get a real bike, you lazy !#&*"...
