The ZBoard 2 is the lightest, fastest, longest running weight-sensing electric skateboard ever. Simply lean forward to go and lean back to stop. The deck of ZBoard 2 includes front and rear weight-sensing foot pads. Each foot pad senses how much force you apply and analyzes this information with an onboard computer linked to an electric motor. The speed control is completely variable, cruise at walking speed or race to speed of 20 miles per hour. The ZBoard 2 has two models, the Blue Edition with 16 miles/charge and 16 lbs and Pearl Edition with 24 miles/charge and 18 lbs.
