Description

Ride with Confidence

Inspired by naked-style motorcycles, the KS-S18 combines a bold open-frame design with practical performance. Built for riders who want more than just a commute.

The KS-S18 is one of the first electric unicycles in the world with a fully functioning shock absorber. The wheel moves inside the body, and the visible suspension at the rear absorbs bumps and rough terrain.

High-Built for All Terrains

With a large 18-inch wheel and 3-inch tire, the S18 is perfect for both urban streets and forest trails. Adjust tire pressure for extra grip on uneven surfaces.

A built-in telescopic trolley handle automatically cuts power when lifted. It’s easy to roll and carry upstairs or into public transport.

Next-Level Battery Tech

Powered by 21700 battery cells, the KS-S18 offers higher energy density and longer lifespan than older 18650 batteries. This means a broader range and improved long-term performance.

Like all King Song models, the S18 connects to a mobile app, where you can adjust ride settings, customize speed limits, and manage safety alerts.

Comfort Meets Safety

The 1600-lumen front headlight automatically switches between high and low beams. The rear brake light activates as you slow down—ideal for riding day or night.

Soft side padding protects your legs on longer rides. We recommend always wearing a helmet, plus knee and wrist protection as needed, especially for beginners.

FAQ

FAQ

Are electric unicycles street legal in Europe?

In most European countries, electric unicycles fall into a legal grey area. Some jurisdictions permit them on bicycle lanes if limited to 25 km/h, while others classify them as motor vehicles requiring registration and insurance. Always check local laws before riding.

How fast does an EUC go?

It depends on the model. Many city‑oriented electric unicycles top out around 25–40 km/h. Under ideal conditions, high-end off-road or performance models can exceed 70 km/h or more.

How to ride electric unicycle?

Learning an EUC takes practice. You’ll start by balancing slowly, using body lean forward/backward to accelerate or decelerate, and shifting your knees/hips to steer. At Voltride, we offer professional riding training in Tallinn — schedule a session with us to accelerate your learning curve.

What is the typical battery lifespan of an electric unicycle?

Most EUC batteries are rated for 500–1000 complete charge cycles. Moderate use often equates to 2–4 years of reliable service.

How long does it take to charge an electric unicycle?

Charging typically takes 4–8 hours, depending on battery capacity, charger quality, and whether the device supports fast charging.

Can you ride an electric unicycle in the rain?

Many EUCs are built with water resistance ratings (IP codes) to handle light rain. But intense downpours, deep puddles, or heavy water exposure can damage internal electronics. Ride with caution and avoid submersion.

What safety gear should I wear?

For all riding, use at least a certified helmet, wrist guards, knee & elbow pads. For speeds over 40 km/h or off-road, consider body armor, full face helmets, and protective jackets.

Safety and Warnings

Warnings

⚠️ WARNING: Failure to follow these instructions might lead to serious injury.
⚠️ WARNING! Tilting the unicycle forwards or backwards will cause the wheel to move forwards or backwards, maintaining the pedals in a horizontal position. When sideways, the wheel does not balance itself.
ALWAYS ride an electric unicycle with a helmet and arm, elbow, and knee protection. We recommend the use of a helmet with chin protection and special protective clothing (motorcycle jacket and trousers) with back protection.
DO NOT charge the unicycle if the charge port or power cord is wet. DO NOT charge or use your battery if it is damaged or shows traces of water.
DO NOT ride the electric unicycle in the rain or through puddles. Water damage is not covered under warranty, and the warranty will be voided. It is forbidden to wash the electric unicycle with water or other liquids.
DO NOT ride the electric unicycle if it has been damaged.
DO NOT ride the electric unicycle on stairs or over obstacles.
DO NOT store the unicycle in wet conditions or at temperatures below 15°C.
DO NOT modify the electric unicycle or use accessories not approved by the manufacturer.
DO NOT rest your feet on anything other than the pedals when riding.
DO NOT exceed the carrying capacity of the electric unicycle.
DO NOT use a mobile phone when riding a unicycle.
DO NOT touch the motor after riding. It may get hot during the ride.
DO NOT ride the electric unicycle with passengers. An electric unicycle is designed to transport one person.
DO NOT ride an electric unicycle if you are pregnant, have balance problems, or have other contraindications.
DO NOT ride an electric unicycle if you are under the influence of alcohol, drug,s or other potent medications.
DO NOT attach objects to the electric unicycle that may impede steering or balance. The device is not designed for transporting objects.
DO NOT ignore warnings and malfunction messages on the screen, in the app on your smart device, or audio alerts on the electric recliner.

Riding an improperly serviced electric unicycle may result in an accident or failure of the unicycle and will void the warranty.

This equipment is not intended for acrobatic use.

This equipment is not intended for commercial or rental use.

Always obey traffic laws and local requirements when riding an electric unicycle.

Be familiar with and take into account the overload and other protection functions and warnings programmed into the bike's software:
- Speed and acceleration limit according to rider weight, battery capacity, and charge
- Automatic switch-off if the unicycle's side inclination exceeds 45 degrees
- Overheating protection
- Power short circuit protection

DO NOT rely solely on the above wheel protection measures—you are primarily responsible for your safety. When the battery charge drops to 60%, avoid sudden accelerations and ride at the maximum speed the wheel allows. The performance and safety of an electric unicycle are directly related to the battery charge level, which will decrease significantly as the battery is discharged.

⚠️WARNING! Braking abruptly or in a bend can cause loss of control, which can lead to serious injuries. Serious injury. Always ensure your road is safe and drive at a speed appropriate to the driving conditions.

⚠️WARNING! As with any mechanical component, the electric unicycle is subject to stress and wear during use. Different materials and components age and wear differently. If the expected service life of a component is exceeded, it may break unexpectedly, causing injury to the user. Cracks, scratches, and discoloration indicate that a part under high stress has exceeded its service life and should be replaced. Such latent defects are checked during regular maintenance. At the same time, the user must also watch for such defects and service the wheel if necessary.
