Backfire Mini Super Portable Electric Skateboard (On Indiegogo 10/25)

Double Kingpin Truck with Great Carving Experience

Many of you may be wondering what would it feel to ride a skateboard with such big wheels? The answer is: it's just like your old ones, if not better. Because Ranger X2 is equipped with double kingpin trucks, minimum turning radius is only 2 meters! Together with the 6.5" wheels, you get all-terrain riding experience without sacrificing maneuverability, it still gives you the same if not better carving experience!

Fully Water Resistant and Dust Proof Motors

Ranger X2 is a real all-terrain skateboard with water resistant and dust proof mechanism. Major components on the board like the ESC module and the battery modules are covered and protected with special materials, now, you don't need to worry about hurting your board when riding in bad weather.

More Efficient Electronic System

New Backfire Ranger X2 uses 12S 50.4V electronic system, 12S battery, ESC and motors.

Here is why Backfire chooses 12s 50.4V high voltage system as the next general-purpose system.

When energy is conserved, it can be converted into different forms. The electric energy generated by the battery will convert, in part, into heat.

If one can reduce the heat generated by the battery, the saved energy can be used to generate more power, thus more range.

There will also be heat generated by the friction of the motor parts. When the current is reduced, the energy consumption from the battery can be greatly reduced, and, in turn, so will the heat generated by the motor.  

This energy saving is in the form of kinetic energy, which supplies the motor. That is to say, by reducing the energy consumption and improving the efficiency of the whole system, the skateboard can achieve more range.

This formula may be familiar: P = UI

Power = Voltage * Current
 
When the input power remains unchanged, as long as we increase the voltage, we can reduce the current, so as to reduce the heating of the whole system and improve the efficiency. Therefore, the 12S electronic system (voltage is 50.4V when fully charged) is far superior to the 10S electronic system (voltage is 42V when fully charged), which is commonly used in the market.
