The YikeBike is an electric, folding "mini-farthing" (think "penny-farthing") bike -- €3,500 gets you a 10kg electric scooter that folds up to the size of a cymbal set and travels 10-20km on a single charge at 20km/h. Ideal for short-hop commuters who are too lazy to pedal a bicycle, as well as anyone who doesn't think a Segway is dorky enough!
But it is a sweet bit of design.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
