LOS ANGELES – Lit Motors calls it the C-1, but the San Francisco start-up’s untippable motorcycle seems nothing short of magic. It uses gyroscopes to stay balanced in a straight line and in turns in which drivers can, in theory, roll down their windows and drag their knuckles on the ground.

Is it a motorcycle? A car? Neither. It’s an entirely new form of personal transportation, presuming it gets off the ground.

The all-electric vehicle is fully enclosed and uses a steering wheel and floor pedals like a car. But it weighs just 800 pounds and balances on two wheels even when stopped, making it more efficient than hauling around a 2-ton four-wheeler and safer than an accident-prone bike.
