King Song S18

$1,899.00

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.

Willing Suspension of Disbelief

REV Rides: Absolutely cannot be overstated.. The Best People. I called to setup my S18 pickup date and explained that I may need a bit of help setting up the wheel due to days before having had a lil' spill (always wear gear) making my right arm tender and mostly useless. I know they have been busy so I didn't expect too much, I was wrong, the wheel was completely setup and I was provided a 15min tutorial from a rider that was experienced with this specific device, offering me personal insights from a first-person perspective. I could go on but think that you get how happy I am, the last thing that needs to be mentioned here is the proof that going the extra mile is standard here; 3-D printed aftermarket pedal clips, provided and installed for free without request. My pedals never fault and always work perfectly. Thank you very much to all of you!

Wheel: When I look at this device I see the precipice of perfection, I can notice the subtle way it intends to stay relevant in the years to come. Beyond ascetics (which are very pleasant) the design is elegant and pushes innovation of the industry as whole. The ride is soo smooth that I often look for rougher terrain to flex the shining achievement of the wheel. I understand the idea behind the turn-signals but they do not function in a useful way, please disable. Riding at speed is very stable and the foot pedals are slim and shapely, also night rides are well lit by the automatics headlights. I have about 100 miles of S18 under my feet and feel like each mile only gets better, like a good pair of shoes you have to break it in until the fit is personal and worn to your style.

Cuts out and cheap plastic breaks

I rode the Kingsong s18 for a total 20 minutes since receiving it yesterday. Took it to a MTB trail that I’ve ridden with the Gotway MPS countless times. 20 minutes into the ride, it cutout and broke the fender. This happened 5 more times before I realized my knees couldn’t take another unexpected fall.
This is a pathetic effort by Kingsong.
Battery was 100 percent charged when the ride started.

Smooth Transaction.

Rev Rides provided their own product improvement pieces!!!

Very happy customer

For my first eu I decided on the King Song S18.
My thinking was not just a great looking machine but a great 64 year old man scooter.
After adjusting the shock my joints have not felt any stress.
My new beautiful machine came with a few issues, I assume from shipping but RevRides had my back and resolved those issues immediately. I am happy with my first eu and pleased I chose RevRides when purchasing.
Happy riding all, Tim Grant

Just looking at the ZERO 10X can raise your pulse. Originally designed for off-road riding, this body plan was so successful that the designers adapted the scooter for urban riding.
