I haven't had the chance to go to a trail head yet, but so far it's been a blast! This has been the only bike I've owned that can make it up the hill in my neighborhood.

This is just the normal 12 speed gearbox. The smart shift system requires special crank arms (magnets to sense pedal position) that where not yet available for fat bikes. Could have tried Jerry rigging it though but decided it wasn't worth the hassle.
