King Song electric unicycles are a fire risk, government warns

Some electric unicycles may be unsafe due to the risk of fire, the U.S. Consumer Product Safety Commission warned. 

The federal agency is urging owners of the King Song electric unicycle model number KS-16S to get rid of them at a recycling or household hazardous waste drop-off site. 

The CPSC knows of one fire related to the unicycles that resulted in smoke inhalation injuries to two people and substantial property damage to a commercial building, it said on Tuesday.
