King Song S18

Price Match Guarantee

  • VALENTINES DAY SALE: $100 OFF

    This newest edition to the King Song EUC line up has a sports bike inspired design with its aerodynamic air intake system and aggressive curvature design. Perhaps the most noticeable change to the King Song design is the variable linkage dampening air suspension system using 200-57 suspension with 100mm travel.

    King Song takes the EUC experience to a whole new level with many improvements from their previous models. This wheel is crafted with an ergonomic design to connect wheel with rider. Headlights are 2 times stronger to the 16X with a 2*5w (high beam) and a 2*4w (short beam) with automatic sensor to switch between modes. The ergonomic handle is designed for pushing and lifting which can be hidden inside body frame when not in use. This is the first ever high performance wheel with limited wiring and all key components housed on PCB. The rear light is the hub for all ride information, displaying the battery level, braking and turning signals. To top it off the there is a 21700 battery system for better efficiency to space ratio.

S18 Final Production Changes

  • Adjustable Pedal -Structural
The pedals are adjustable allowing riders to lower the platform by 2cm. This allows riders of different heights to have better control and increased comfort levels on the S18.

  • Mudguard- Back fender
Previous mudguard was secured by glue and one screw. The final production is secured by a total of 3, one on each shell and one in between with the addition of glue.

  • Tiring rubbing noise
Some prototypes experienced a rubbing noise issue. The tyre we used on prototype is a little bit wider than massive production, and the mainboard holder tubes had some errors, so the tyre might be pushed to one side and scratched the body shell. We’ve adjusted the mouldings/dimensions to eliminate these issues.

  • Wobbliness
Users experienced issues where the wheel would wobble when braking. After testing we eliminated the issue being suspension related but was rather padding related. Users could not grip the wheel when braking hard, we have since increased the PU pad thickness from 4mm to 12mm.

  • Top of wheel hurting inner knee.
The padding was not thick enough causing the knee to interact with the harder elements of the wheel. Final production will have increased the PU pad thickness from 4mm to 12mm.

  • Body shell
Some users experienced the case not being durable enough when crashing. We started using a material with more flexibility causing it to be less brittle. ABS+PC.

  • Outer shells popping off
Users experienced the white body panels coming off when crashing, we have increased the thickness of the clips so they don’t come off as easily.

  • Handle
Sometimes the trigger button gets stuck, we’ve added a crystal silicon logo above the button to create a uniform force downwards.

  • Steel Slide
To increase the durability of our suspension we have changed the sliders from aluminum to steel. The steel is treated to protect it against elements.

  • Suspension support frame
Suspension support frame is changed from space grey to gold.

  • Padding durability
We have changed the material for the padding so it doesn’t rub off as easily.

I bought 2

The 2 S18s were his and hers Christmas gifts. At 51 and 48, we wanted to try something new. We started riding on the v5f 3 months ago. Best thing we ever did! Looked into upgrading and S18 seemed perfect for both of us. Rev rides is local kinda so I ordered on black Friday and went and picked them up. So far we are happy with them. Definitely a upgrade from the v5f. Thanks to Rev Rides for being so helpful. If there are any future purchases... It will definitely be through them.

This is my first EUC

I had never ridden a EUC. In fact I hadn’t even seen one out in the wild. So I wasn’t really sure what to get. After tons of YouTube videos I decided on the KS-S18. I can ride a pedal unicycle so I had some of the basics but the S18 made it smooth. Really enjoy it. I will also add that I asked a question and Rev Rides answered right back. Great Black Friday price too!

Great suspension wheel

My second wheel, first with suspension, and I'm loving it. Soaks up the bumps well and haven't bottomed out yet. Tracks pretty well, rides great.

Fantastic wheel- no regrets!

Bought the S18 after 10’s and 10’s of hours of reviews on YouTube. Wanted the S22 Eagle but talked my self into getting the S18. I knew I would want another wheel and the S18 is a great first wheel I can see myself using even after I get my dream wheel. Rev Rides were on it, I will buy another wheel from them. You won’t regret the S18 if it’s on your radar.
