Electro-Superbike... "the Ferrari of electric bikes." it can zip you up to 28 mph, and then you can assist with the pedals at the same time. Beyond its speedy road capabilities, it's a trainer, too, letting you ride it in stationary mode while it simulates the hills and valleys of real-world bike riding. And, you can simulate that same terrain while you're riding on flat land. It's pretty light for an electric bike, but its price isn't: $9,250.
