Razor is recalling about 158,000 RipStik electric motorized caster boards because of a fall hazard.
The U.S. Consumer Product Safety Commission said the rear wheel can stop rotating and lock up while in use, posing a fall hazard.
The boards have two wheels, a hub motor and a lithium-ion battery.
Officials said they have a wireless digital hand remote that controls the speed up to 10 mph, the manufacturing date is on the bar code label on the bottom of the product, Razor USA LLC is embossed on the bottom, "RipStik" is printed on the top of the board and they are blue and black.
Razor said it has received more than 700 reports of the rear wheel locking up, resulting in four injuries, including one loose tooth and three scrapes and bruises.
Consumers are being advised to immediately stop using the recalled caster boards and contact Razor to receive a free repair kit.
The CPSC said the boards were sold at Target, Toys "R" Us, Walmart and other stores nationwide. They were also sold online at Amazon.com, Razor.com, Target.com, toysrus.com and Walmart.com and other websites from February 2016 through this month for about $180.
