Zero emission & no pollution
All the power source of FreeGo F4 comes from 72V lithium battery, and it is convenient to charge by using power supply for household. You can enjoy driving about 45-50km at the speed of 20km/h after charging, without any emission or any destruction to the environment.
Low energy consumption
FreeGo F4 has an extremely low cost_0.03/km per person, 20 times less than the cost of a car with displacement 1.2L, which is 0.63/km per person. It also saves more energy than an electric vehicles because the mass of F4 is only about 55kg whereas the weight of a traditional electric vehicle is more than 1 ton, which leads to more energy consumption due to its dead weight.
High efficiency
Circular energy reserving system is another sparkle of F4. By utilizing the control module of gravity, F4 can brake and stop by judging the center of gravity rather than configuring a traditional brake system based on friction. And as a result, during the process of deceleration, kinetic energy converts to electric energy being stored in the battery without losing any heat energy due to friction. In a word, there is no energy waste.
Ideal Selection
FreeGo F4 is an ideal and advanced travel tool in an extremely crowded city because of its small size,reliable security and unique driving technology. The innovation of its structure design is based on the principle that “A little body often harbors a great soul”. With the fast development of modern metropolis, F4 is now being accepted as a superb solution for individual traveling.
