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
“If you’re searching for the perfect gift for
the city cyclist in your life. Fortified
Bicycle has you covered."
"I can say it feels like a great investment to me after seeing it and riding it in person"
"If a bike does go missing, the security team trawls Craigslist and eBay, where more than 80 percent of stolen bikes are resold"
"Fortified set out to create the ultimate city bike. This is a bike that will survive pedaling the mean streets, but more importantly will be there where you locked it up when you come back"
"Fortified are keen to emphasize that their bicycle is not just special for its anti-theft properties. This, they say, is a bike designed for the city"
