Freego scooters includes Electric scooter (E-bike) and Self-balancing scooters and others. Finally Self-balancing scooter brought us a new hope after 2 years research and development on personal transportersIt means that you can drive it freely according to your thought,just go anywhere freely and enjoy gliding.Freego senses the lean of the rider with the assistance of two-dimensional inertial navigation system and two accelerometers that sense the angle of the FreeGo with respect to gravity at 100 times per second. It balances the rider by applying forces to the ground in the direction of the lean. If you lean forward the FreeGo applies motor torque to the wheel to push it forward, bring you upright and balance you. When you lean back, it applies reverse torque to slow you down and balance you accordingly.It can save the time spent on traffic and improve the efficience.It is green instrument.It conforms the requirement of new energy in new century.
