The Consumer Product Safety Commission said some of the company's PowerWing three-wheeled scooters have sharp edges on the bottom of the platforms where riders place their feet.
Importer Razor USA LLC has received 10 reports of this platform cutting users on the ankle or Achilles tendon. Four of these people needed tendon surgery. Three received stitches.
Razor also recalled about 30,000 Chinese-made Dirt Quad electric-powered, ride-on vehicles because the throttle controls can fail and cause the vehicles to surge forward unexpectedly.
The company has received 60 reports of unexpected power boosts and two reports of injuries.
Both products were sold by authorized Razor dealers around the country. The scooters were available between October 2007 and September 2008. The Dirt Quad vehicles were available between August 2006 and September 2007
