WHAT RIDERS ARE SAYING

"In the five years I've spent commuting in Chicago and NYC I've had 2 bikes stolen (and countless lights, too). Being able to confidently leave my Fortified bike locked-up anywhere I want outside won't just be convenient, it's going to change my daily routine." - Tina J. Brooklyn, NY

"I love my triathlon bike but there's no way I'd ever leave it outside. I was 12th in line to get a Fortified Single-Speed because when I tested it it was fast and light, but the beefy tires and tough frame are tailor-made for city cycling." - Aman A. Boston, MA

"Commuting in SF, my bike needs to be built for the city but also handle all the hills. I rode the 8-speed and it was perfect - the disc brakes stop fast and the shifting is super-smooth. It's perfect for SF." - Lily R. San Francisco, CA
