Meet the TWIKE: a 2-seat electric vehicle you can buy today. It is environmentally-friendly and efficient. The design looks pretty decent. Each vehicle is fitted with lithium batteries. Its ergonomic joystick steering offers you a more fun driving experience. Best of all, an additional pedal mechanism is included, so you can use this as a fitness machine. It is a bit pricey but TWIKE is fun to consider if you have the money for it (see the calculator below).
