14d

The KingSong 14D is a 14-inch self-balancing electric unicycle positioned by KingSong and reviewers as an entry-level, beginner-friendly machine. It pairs an 800 W rated hub motor (2400 W peak) with a non-removable 420 Wh battery built on 18650 cells, rated at 60 V DC and charged to a maximum of 67.2 V. KingSong quotes a 30 km/h top speed, up to 40 km of range and a 120 kg maximum load, with a net weight of roughly 14.5 kg that keeps it portable for stairs and public transport. The 14D sits in the middle of KingSong's 14-inch family: it shares the 800 W motor and 30 km/h ceiling of the 14S but carries half the battery (420 Wh versus 840 Wh), while the smaller 14M drops to a 500 W motor, 174 Wh and 20 km/h. The wheel runs a 14 x 2.125-inch pneumatic tyre with no suspension, and adds quality-of-life features common to the line: a telescopic trolley handle with anti-spin lift sensor, honeycomb pedals, customizable side LED strips, headlight and taillight, Bluetooth speakers and KingSong-app connectivity over Bluetooth. It is UL 2272 certified for electrical and fire safety.
