KS-18 A King Song 18" 800w - 840wh unit - Lightly used condition. Motor is making a grinding sound - doesn't ride smoothly


This is early technology, and these are test / sample units, so there will be revisions in the future.

Shipping to the continental US is always free!

The King Song KS-18A is a fast mid-range self balancing electric unicycle with a large 18" wheel size. Among the fastest wheels on the market, it is comparable in speed to the famous Gotway unicycles of the last generation, however the quirks in the technology have been ironed out. King Song is a bigger company and is more focused on developing safety features and improving ergonomics.

The large 18" size gives you an ultra smooth ride, and allows one to actually sit on the unit if so desired, and so a cushion is included. See pictures of cross-country riders here.

These units all include the new wireless update, with an app for iOS and Android!

What that means to you is you get a super smooth and stable, fast, long range ride. Overall, an excellent balance of features at any price, but offered well below the competition
