Nearly one million Trek bikes are being recalled in the United States and Canada after an injury that left one rider paralyzed.

Included in the recall are 900,000 bikes in the U.S., and 98,000 sold in Canada, according to the Consumer Product Safety Commission. A quick-release lever on the bike's front-wheel hub can come into contact with the front disc brake assembly, resulting in either complete wheel separation or the wheel coming to a sudden stop.

Three accidents have been reported, and Trek said all included injuries - some to the face, a fractured wrist and one that resulted in the rider becoming a permanent quadriplegic.

Included in the recall are all models of Trek bicycles sold from September 1999 to 2015 that are equipped with front disc brakes and a black or silver quick-release lever on the front wheel hub. This lever can open beyond 180 degrees, coming in contact with the disc brake.

Bikes with front quick-release levers that do not open a full 180 degrees are not included in the recall.

The bicycles were priced anywhere from $480 to $1,650. Trek advises consumers to immediately stop using the bike and contact an authorized Trek retailer for free installation of a new quick-release lever.
