as a 29” tire but with extra tire width and air volume for traction on
almost any surface.

The Pine Mountain E features brazed-in cargo attachment points
throughout the front triangle for carrying all of the water and gear
one needs for a proper adventure. The Bedroll Bar features a 50mm

phones, cycle computers, or whatever else catches your fancy.
