Yike Bike

Despite making you look like you’re riding on a unicycle, the Yike Bike ($4,450) boasts an avante-garde design that’s an engineering success. It’s foldable, electric, chainless, tops at a little over 15 mph and weighs 22 pounds thanks to its carbon fiber composite. Additional features include a lithium battery holds enough power for a six-mile ride before recharging, anti-locking brakes and LED lights.
