I feel like a traitor, but here's my position right now. IF the YikeBikes were sold in the US, I would consider selling my Segway in favor of one. Here's why - It's compact, and would likely be viewed as a bike, hence not resisted as much.
I have moved further West where getting somewhere means leaving 20-30 minutes earlier just to walk to the subway. A Yike Bike would allow me to zip there, then fold and take it with me. Even if I zip to the subway via a Segway, it'll stand out more. Plus, how does one get a legally unregulated Segway on a train with cops everywhere? Paying for tickets isn't in my budget.
The elevators in my new place are smaller, but there's more residents. The Yike Bike folds small, which is ideal in cramped spaces.
Don't misunderstand. I love the Segway. I think it's the best transportation alternative invention. My desire for a Yike Bike is based on stupid, baseless Segway resistance, which makes using it difficult.
While moving, I had many tasks to take care of. Most involved running to one store to grab a few items, then to another, etc. I wasted time, money on subway and cab fare, and my feet were throbbing.
I would prefer to have used the Segway, zipped to a store and zipped back home. If NYC would welcome Segway use, I wouldn't even LOOK at a Yike Bike. Take that back. I'd look at it and go, "Yikes! No thanks."
