Product Description

CAUTION:  The King Song range of eWheels are among the highest performing & most capable eWheels available today. Although these eWheels are exceptional safe (more below), because of the extreme top speeds, riders are strongly urged to wear knee/wrist guards & a helmet, at a minimum, for protection.

What’s new in this updated version of the KS 18″?
Most of the improvements are to be found under-the-hood, which results in one of the best performing Electric Unicycles made today:

  • 1680Wh Battery Capacity Option: this setup is composed of 16s8p, meaning it has 128x 18650 battery cells! This is compared to just 16x battery cells found in an entry level Wheel, or 30-32 cells in mid-range Wheel.  Not only does this provide more range, but because the load is balanced over each parallel pack, the individual battery cells are subjected to less ‘stress’ than their smaller pack relatives, which has the benefit of increasing the pack’s lifespan.
  • Active control-board cooling: a temperature activated fan extracts unwanted heat from the electronics.  Control-board overheating has been especially problematic when the motor power exceeds 800W.
  • Improved motor: King Song claims this provide at least 30% more power than the previous generation 1,200W and nearly double the output of the 800W class of motor.
  • Pedals: larger pedals with better anti-slip surfaces.
  • Other improvements: electrical switching (MOSFETs) have been replaced with components that offer 20% higher power than before, larger gauge wiring, redundant fuses, firmware tweaks for better ride experience.

How does it Compare to the other King Song Wheels?
The new 18B has a higher top speed, more battery capacity, a more powerful motor & an improved control-board, for raw untamed performance, it’s in a league of its own.

King Song 18 Wheel Comparison Guide

What are the benefits of having a larger Wheel?
Those customer who choose a 18″ find the following advantages:
1) The 18″ gives the sense of greater stability, & paradoxically many new riders find it easier to use for the first time.
2) Larger Wheel has superior off-road capability, especially on undulating or uneven surfaces.
3) There is an included padded seat that goes over the handle, that serves both as side padding & as a seat as well.
5) An addition 1.5″ of ground clearance makes the less susceptible to pedal clipping from ground objects

If I purchase the 840Wh version, is it possible to add on a battery upgrade?
Yes, while the base model is a 840Wh model (which comparatively is still a colossal amount of battery capacity & should offer between 30-40 miles of range), there is plenty of room within the Wheels body to contain another 840Wh pack.

Is the 18″ Wheel water resistant?
Reasonably water resistant: The control-board is housed in a separated chamber that’s removed from the Wheel housing; in addition, the electronics have been coated in a protective film covering the surface to keep moisture out.

To dissipate heat generated by the control-board, a fan has been installed under the top cover. Under the cover is a mesh to keep out dust, debris & water. However, under heavy rain, it’s possible for water to find it’s way down. We will be providing Customers with both the non-perforated standard covers & the slotted ones—the idea is to use a standard covers in wet conditions & the slotted ones when the weather is fine & dry.

What are some of the safety features of a King Song eWheel? Many eWheels being sold today are under-powered, this poses the single greatest risk to riders, especially in situations like going up a curb slowly. The King Song eWheels are exceptional, in that they offer an enormous amount of power for all conditions, in short power = safety. Also the maximum top speed is electrically controlled so that the Wheel should not cut-out when cruising at the maximum speed.

Key Features:

  • Best power & highest (controlled) top speed
  • Fast-charger: 2.5x faster charging than the standard one
  • Bluetooth speakers: use your eWheel as a portable music player
  • Pedal pitch: the owner can set the ride tilt-angle of pedals to their preference, making the Wheel more comfortable to ride than others without this
  • Light sensitive LEDs: as it becomes dark, the King Song will automatically turn-on the front headlight, illuminating your path ahead
  • Batteries: top quality 3.5Ah Sanyo batteries with an expected lifespan of between 3-5 years of daily use
  • Full one year US warranty: if there are problems, or manufacturer faults with the Wheel, we’ll pay for the shipping getting it repaired with minimal delay
