From Rookie to Master

Upgrade. Save. It’s a win-win-win.

We've planned everything for you to seamlessly transition from novice to expert on your electric unicycle journey. When your current "basketball" no longer fits your needs, you can take advantage of a special discount on the high-performance EUCs of your choice. We won't take back the S9 "Basketball" because it's the most cherished memory you'll ever have from learning to ride. Let the "basketball" that supported you in your early years bring joy to your children or other family members.

For all the EUCs riders

We understand that an EUC is expensive, and we also know that you need to improve the performance of your equipment as your skills improve. That's why we've introduced this program for riders with different time frames.

To create a better future, we encourage the use of EUC travel and help reduce traffic congestion and air pollution in urban environments by reducing reliance on traditional modes of transportation.

Carefully designing products for a sustainable future
We will design products using more sustainable materials, including those obtained through closed-loop recycling. Exemplary products - some of our tires contain bioplastics from trees.

Do I need to return parts to get this service?

You do not have to. In fact, this amounts to a free event and you don't have to lose your old device.

Is there a way to track my upgrade status?

Yes. If you participate in the S9 Upgrade Event, we will create a manual order for you and include a tracking slip number with your order, so you can check the operational status of your new device in 17track.net.

Which of the high-performance EUCs can I upgrade with the S9 "basketball"?

You can choose any KS electric unicycle and let us know!
