Trek's Lync 3 is a tricked-out commuter bike like nothing else out there. It starts with a great-riding lightweight aluminum frame, and quick, 700c wheels with wide tires that rip through the city and country alike. The Lync is all about convenience, with reliable, easy 9-speed gearing, all-weather disc brakes, full fenders and reflective stickers and tires. Plus, the Lync's on-board lighting system builds maximum visibility right into the bike! With an easily removable, USB-rechargeable lithium ion battery and an adjustable, 500-lumen headlight and 2 taillights, this bike is ready to go, 24 hours a day. There is literally no excuse not to ride!
