The U.S. Consumer Product Safety Commission announced a voluntary recall of about 2,100 Outer Edge Snow Bikes from Tech 4 Kids Inc., of Canada.

The front ski can crack or break, causing the snow bike to stop suddenly and posing a fall hazard to consumers. Tech 4 Kids has received three reports of consumers falling off the recalled snow bikes and sustaining injuries as a result of the defective front ski cracking or breaking. Injuries included a cut requiring stitches and a dislocated shoulder.

The recall includes OUTER EDGE brand Snow M Ski-Doo and the Snow MX-X Games snow bikes. The Snow MX-Ski-Doo snow bike is yellow and black with “Ski-doo” printed on the steel frame and on the front ski. The Snow MX-X Games snow bike is blue and black with “Snow MX,” a skull and swords printed on the steel frame and on the front ski. “OUTER EDGE” is printed on the snow bikes' packaging.

The items were sold at Costco, sporting goods stores and other retailers nationwide and online at Amazon.com and Walmart.com from September 2010 through January 2011 for about $150.
