It is the world's 2nd smallest pocketsize radio-controlled micro car from Japan. The Bit Char-G (pronounced as 'bit charge'). It is an adaptation of mobile phone vibrator technology. The development of this cutting-edge ultra-miniaturized motor allows the Bit Char-G to have an overall length of only 60 mm (about 2.25") and is so small that you can maneuver it on your desk around coffee mugs, keyboard & other objects.
