Stile is recalling about 650 of it folding bicycles, saying the bike's frame can crack at the hinge on the top tube, posing a fall hazard. The recall involves Link Uno, Link D7i, Link D8, Link P9, Link P7i, and Link P24h models of Tern brand adult folding bikes. No incidents or injuries reported in the U.S. The firm has received 11 reports of the bicycle frames cracking including five reports of minor scrapes and bruises from outside of the U.S. Consumers should immediately stop using the bicycles and contact Stile Products or take the bike to an authorized dealer. Consumers will receive a free replacement frame and have it installed at no cost or they can upgrade their bike to one of three designated models at an additional cost.
