  • Why we Designed it:

    We wanted to create a gravel bike we would ride and own. Gravel bikes are all over the place these days: huge tires, suspension, storage, aero, integrated, etc... In our opinion, those ruin the very thing that makes the gravel bike great: its simplicity. With BigLeaf, we designed it for a relaxed fit, clean lines, and nimble handling. No gimmicks, just a simple, reliable steel gravel bike.
