Well, they
are true beach cruisers not poseurs. Decisions, decisions. Colnago or Minnesota 3.0?
As as I live next to 28 miles of Pacific Ocean beach...fat wins mostly. It's a brutal workout. Imagine rolling 2 psi rear and 1 psi front through soft sands. Hard sand means I can roll at 12 mph+ but that does take serious cardio. It's like a perpetual 1-3% grade. Then there's wind. A buddy who was a Euro
domestique for several years says the fatbike on a beach is the greatest mix of cardio & leg strength training he's ever done.
I just ride and I usually have the beach to myself.
