Breezer Steel

Breezer Steel 4130 CroMo: The material Joe started with, and still the staple material that most Breezer bikes are constructed from.  Chromoly tubing has earned its place in cycling’s list of top-rated materials as it offers incredible strength-to-weight properties, up to 5 times the fatigue & tensile strength of 6061-Aluminum, while also offering excellent ride quality characteristics. Add to this the ability to repair the material after welding and you can understand why adventure riders have trusted this material most to safely carry them around the world for decades. Learn More

Multi-Mount Capability

Multi-Mount Capability: A signature feature on all adventure models. Frames and forks come designed with multiple mounting options for racks, fenders and bottle cages.  These features allow you to fully customize & personalize your Breezer for the type of riding you love most.  Whether it’s loading up with five water bottles to traverse across barren wastelands or outfitting some new waterproof bags on front & rear racks for a weekend bikepacking trip, we got you covered!  Learn More
