More than 900,000 bicycles in the U.S. and Canada have been recalled due to a problem that can cause the bikes to suddenly stop.
Trek bicycles equipped with front disc brakes from model years 2000 through 2015 are affected by the recall.
According to the Consumer Product Safety Commission, the quick release lever on the front wheel hub can open far enough to come in contact with the disc brake, causing the front wheel to come to a sudden stop or separate from the bicycle.
Three crashes have been linked to the issue. One resulted in quadriplegia, one resulted in facial injuries and a third resulted in a fractured wrist.
The bikes were sold in stores nationwide from about September 1999 through April 2015 for between $480 and $1,650.
Anyone with an affected bicycle should stop using the bike immediately and contact a Trek retailer for free installation of a new quick release on the front wheel.
