Bit Char-G (pronounced Bit Charge) is the world's smallest pocket-size radio-controlled micro car from Japan. It measures only 2.25in (60 mm) in length and is available in several different models and colors. The current models available are: Mazda RX-7 (Red), Mazda RX-7 (Yellow), Toyota Celica (Black), Toyota Celica (Silver), Honda S2000 (Silver), Honda S2000 (Yellow), Nissan Skyline GT-R (Blue), and Nissan Skyline GT-R (White).

Also, it is important to note that depending on which car you get, it can run on 1 of 4 different radio frequencies. This will allow you to purchase multiple cars and run / race them at the same time.
