Frequently Asked Questions About S9

Please read our frequently asked questions to find out more.

What is the relationship between Kingsong and Top-feel?

Topfeel is the official website of KingSong, which will be launched to all retail customers in 2023 and will be managed directly by KingSong.

Why make an S9?

We have found that no EUC on the market today is intended for beginners. So the learning process is always accompanied by wrestling and pain, so we gave birth to the S9.
This little guy that looks like a toy is the perfect tool for you to enter the world of EUC, with unrivaled safety to ensure you can complete the novice tutorials with peace of mind and enjoy the envy of others!

What is an EUC?

An Electric Unicycle, or ‘EUC’ for short, is a powered, single-wheeled mode of transport. EUCs are self-balancing and powered by a rechargeable battery. In non-technical speak, EUCs are the most fun you can have on one wheel!

How do you ride electric unicycles?

EUCs have footrests which you will use to stand on. In simple terms, if you lean forward, you will go forwards, and if you lean back, you will slow down. To turn left or right, simply lean in that direction, and the EUC will do the rest.

Are EUCs Safe?

EUCs should be perfectly safe as long as you follow some basic rules:

  • Ensure you are wearing a helmet and other protective clothing, such as gloves and pads.
  • Wear high-vis clothing if possible
  • Be aware of the environment around you, including other people or traffic
  • Stick to a speed that you are comfortable with
  • Ensure your battery is fully charged before you set off and that your EUC is in perfect working order
Does my ride come with a warranty?

Yes - all vehicles come with a 1-year warranty. For more information, please refer to our policies page.

We also offer extended warranties for all vehicles - click here for more information.

Why are you doing such a "CHEAP" EUC?

It's true that there are over 100 mid EUC models on the market today, however, none of the real wheels are specifically designed for newbies, we've shed a lot of features to make this little toy-looking guy, which only has unrivaled safety to ensure that you can get through the newbie tutorials in peace.

I just want more people to join the EUCs family and work together to protect this fragile world.
