SMALL AND MIGHTY
KING SONG’S 18”
ULTIMATE OFF-ROADER
Featuring NEW built-in suspension, KS-S18 takes on a sports bike-inspired design with aggressive curvatures, applying aerodynamics with an air intake system like never before. With the S18, King Song focused on the user experience to create an ergonomic design that seeks to improve the connection between wheel and rider.

Packed with all of King Song’s now standard creature comforts, such as a robust extending trolley handle and built-in sensors that automatically disengage the motor when you lift the wheel off the ground, KS-S18 makes for an ultra-comfy and practical ride.

Three Columns - Smart BMS
VARIABLE AIR
SUSPENSION
With a unique X-shaped suspension system that allows for up to 4” suspension travel, S18 allows you to turn the suspension on or off as well as adjust the sensitivity. Different pressurization can be adjusted according to rider weight. With an interchangeable component, riders can customize it to fit their personal modification and riding style.
IMPROVED
FEATURE SET
King Song included all of their latest features to make sure S18 riders never left wanting more. Headlights will be 2x stronger than those of the 16X with an automatic sensor that switches between high and low beam. The rear light will display battery level, braking, and turning within a singular unit. Aluminum handle with robust construction means you can comfortably take your electric unicycle anywhere with you without needing to carry it, and it even has a built-in sensor to automatically disengage the motor for those times you need to briefly lift your wheel over an obstacle or up a flight of stairs.
TWO BATTERY
OPTIONS
King Song is now offering the S18 with Molicel P42A high-discharge cells! One of the main complaints riders reported with the OG S18 was the lack of power that the 1110Wh high-capacity LG M50LT packs were able to provide in high-load situations. The P42A model fixes this issue, as these cells can output several times more power than the LG M50LT cells safely. With these two options now available, riders can choose between more range or better performance depending on their riding style and use case for the wheel.

I am so geeked with this KS-S18 as my first EUC. I am about 240lbs (108kgs) and was able to put about 20 miles (32 kms) on the EUC the first week with no issues: temperatures in the low teens is why I road so little. I haven’t had any unexpected issues with performance riding at my weight. The setup was pretty straight forward and any question I had I found solutions to on YouTube, EUCO, and the King Song website. The King Song app was a bit problematic when I tried to create an account in-app, but I decided to use it generically for the wheel without creating an account and it works like a dream. This is definitely a gateway to a larger EUC and I can’t wait until it warms up a bit so I can ride more. Also, EUCO’s customer service was pretty amazing and reached out to me where there were challenges with the shipment.

Bought my first wheel from EUCO and it was a S18. Awesome wheel and I just sold to dip my toes in all the newness!!! Currently I’m looking at V11, V12, V13, and S22. Only one problem though, I loved my S18 so much that I may buy another one!!! I mean do I really need to go 45-85MPH?

It’s been amazing! I do worry about the wobble my wheel does within the housing, but I’ve been told to not worry too much about it. I would love to continue my path in the euc world and some day get something even crazier :)
