How Does It Compare?


King Song 14D Background:

Back in early 2015 King Song’s first breakthrough into the world of Electric Unicycles was their 14C. At the time, it was unique for a 14″ Wheel, in that it possessed, what was then, a massive 64 cell battery pack & a 800W powerful motor & quickly found favour in the enthusiast community. While this Wheel had the raw performance, it also had several failings that held it back from being the success it might have been:

  • Control-board Overheating: if the Wheel was pushed at all, the temperature would quickly rise, forcing the Rider to dismount
  • Width: at over 8″ wide, it was short & stubby, not the most comfortable stance to ride in
  • Design: it was frequently accused of being a bit of an ugly duckling
  • Durability & waterproofing: it’s main weakness was that motor axle that was used had a tendency develop hairline fractures which degraded over time. The water-protective measures were not very good at all

The King Song Engineering team built on the lessons, of the brilliant but flawed 14C, to create the 14D/14S line. It’s now equipped with a larger heat-sink & active (fan) cooling to dissipate unwanted heat build-up during high intensity operation; in the case of the 14D, the Wheel is 2″ thinner; is beautifully sculptured & now has the all important retractable handle alleviating the need to lug it around. On the durability side, there are dozens of small improvements that are almost too numerous to mention, better screw holds, thicker shell; but for durability, the most important improvements are probably the ticker axle & better pedals.

Key Features of the KS14D:

The King Song 14D is the perfect choice for Riders wanting to keep their budget under $1,000, but still have an eWheel which is convenient, practical, powerful, reasonable fast & has 15-20 mile range:

  1. Speed: the cruising speed to 50% battery is 18.6mph, thereafter the speed is gradually reduced to preserve the Rider’s safety;
  2. Power: the 14D is equipped with a 800W (sustained) motor & a tuned control-board that can output several times more than than nominal power output in short burst;
  3. New Control-board: the six MOSFETs (electronic switches that power the motor) have upgraded to 350A of MAX power, up-rated connectors, better power delivery, several under-the-hood improvements;
  4. More Atmospheric LEDs:  there are more programmable LEDs on each side of the Wheel for a greater visual impact;
  5. Integrated Telescopic Handle: the handle is ma
