Considering a fixie bike for commuting in the city? The Fortified single speed is a great alternative to a fixed gear bike. We make the toughest, more reliable single speed bikes. Riding fixie bikes can be extremely dangerous if you're not an experienced rider. It's important to understand that fixed gear bikes require that the pedals are always moving.

Fortified is the only single speed bicycle women and men alike trust to meet the daily needs of a commuter. We pack these bikes with anti theft power from the wheels, to the seat, to the handlebars. Unlike any fixed gear bicycle, for side visibility,  the Fortified Invincible has white retro reflective decals that make you shine.

I love the bomb-proof simplicity of this bike. After 6 months, the bike is virtually maintenance free, rides awesome and I know I can lock it up anywhere.
