Comparison of the King Song S18 vs V11

Inmotion V11 vs King Song S18 Electric Unicycle Comparison & Specs

The Inmotion V11 was announced about a week before the King Song S18, so how do these two new suspension Wheels stack up against each other on paper? In the graphic on the left is a side-by-side comparison of the different design philosophies the two Companies have taken in producing their first suspension Wheel. In short, King Song’s S18 is intended as a comparatively short range ‘sport’ vehicle, with emphasis on being nimble & light, while the V11 offers a larger sized battery pack (the largest produced by Inmotion to date), which could be considered more a Cruiser. At the time of this writing, there has not been a head-to-head test to assess their relative ride qualitie—this information is gap is expected to be answered around mid-May.   

  • Suspension: On paper the S18 has an extra 30mm of vertical travel, 100mm vs 70mm on the V10. Both the S18 & V11 have air suspension that can be adjusted according to the Rider’s weight and/or ride performance. On paper advantage goes to King Song.
  • Battery & Range: the Inmotion V11 packs in an additional 20x LG M50T/18.75Wh 21700 type battery cells within the internal motor cavity, this compares with the S18’s 60x cells of the same type. All other factors being equal, the V11 should yield an addition 12 miles of range.  
  • Max Speed & Motor Power: there are several factors that determine a machine’s true power capability, including the number of parallel battery cells, voltage, controller’s rate-limiting, & the motor itself—a higher wattage motor does not necessary translate into a higher operating speed. On paper, the S18’s 2200W motor has 10% more sustained power, but with only 3x parallels of 20x cells each, the limiting factor of the battery pack may see the two models at an equal pegging (this has yet to be determined). Both manufacturers have set a firmware max set speed to 50kph/31mph.
  • Retractable/folding Handle: here the two models have adopted very different solutions for their trolley handle: the V11 has an external ‘scorpion’ style, which appears improved over the earlier V10/V5F type, while the S18 has the retractable telescopic rails extend through the Wheel’s body, similar to earlier models. From the standpoint of efficiency, the Inmotion V11 appears to use the internal body space more efficiently. 
  • Lighting: both designs have jettisoned the typical side LED atmospheric light-show of models, in favour of dramatically increased headlight—in the case of Inmotion, taillight too—luminosity. The S18 has a unique high-beam/low-beam headlight, that dips when there’s an oncoming light source. Both the S18 & V11 offer substantially higher illumination than found on earlier models.  
  • Weight: in this category, the King Song S18 has a clear advantage in being 11lb lighter than the V11. 
  • Misc: there are unique features found on both models; for instance, the V11 has an integrated folding stand, to keep the Wheel upright; while the S18 will be shipping with a fanless 2.5A/84v charger as standard equipment. Each Wheel is fitted with XL >9″ grippy pedals & the lift for motor disengagement function.

Frequently Asked Questions

  • When is it expected the first video reviews will be made?
    If all goes to plan, the first pre-production S18 will be sent out to our YouTube reviewers around mid-May.
  • If I put a deposit in today, when will the S18 actually arrive? 
    King Song have set a target production release date by the end of June. We have placed our order first in the production queue; if there’s demand, we may have some of the first S18s flown in, at an estimated supplementary shipping cost of about ~$250.
  • How do the shocks work, are they adjustable for different loads?
    In contrast to the comparatively simple pedal arm suspension in the V11, the King Song S18 has taken a completely different approach, where the the whole lower assembly is transferred to a single air shock suspension module, the DNM AOY-36RC-165, at the back of the Wheel, which can be adjusted to the Rider’s preference & weight.
  • What type battery pack/cells are used in the S18?
    The pack is configured in a 20S3P/60 cell configuration, using the LG M50T 5Ah 21700 format cells, for total capacity of 1,1110Wh. The estimated range of this battery pack is 44.5 miles, based on a standard energy usage measurement of 25Wh/mile.
  • How is it possible to have a controller rated for 5KW of peak power, while the cells are only rated for 7.3A output?
    With 3 parallels of 20 cells (72v nominal) x 7.3 Amps, yields only 1,576.80 Watts output; however, these cells are rated to provide up to 80W/each of burst power for up to 10 seconds = 4,800W

  • Does the S18 have integrated Bluetooth speakers for streaming music?
    No, the S18 does not have the typical speakers found on other King Song models. This Wheel is designed around the concept of being more of a ‘Sport’ ,’Adventure’ Wheel than the other models.
  • With so much of the structure exposed, will the S18 be less water resistant than other models?
    The S18 will hold equivalent IP55 weather-protection. While the inner-structure is open from above, the sensitive elements, such as the battery, controller area & are enclosed in sealed spaces. Also, the mud-guard extends through the body, so any spray/wash, should be kept confined within there.
  • Will I be able to use a 5A/84V charger?
    Yes, charging at 5A is still within the normal charging tolerances of the battery pack.  
  • What is the brand/type of tire what will be used? Will there be a knobbly/off-road tire option
