Technology

SHIMANO STEPS ELECTRIC ASSIST
Shimano’s STEPS system is neatly integrated into the frame, with a
lockable and removable battery pack that fully charges in five hours
from a standard wall outlet.

STEEL IS REAL
The Pine Mountain E uses a butted and formed Series 3 4130
CrMo frame with internal dropper routing, cast thru-axle Boost
148mm dropouts, full fender and rack mounts, and a plethora of
bosses for a wide variety of gear mounting options.

27.5+ WHEELS
Large volume 27.5+ roll fast with roughly the same outside diameter
as a 29” tire but with extra tire width and air volume for traction on
almost any surface.

BIKEPACKING ABILITIES
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
rise and a long, straight top bar for cleanly mounting handlebar
packs away from cables and controls, and also mounting, lights,
phones, cycle computers, or whatever else catches your fancy.
Reviews
"...the Pine Mountain E2 is a great-performing modern eMTB with touches of heartwarming nostalgia for mountain bikers of a certain age. And if long backcountry adventures are your jam, you’re just a spare battery and some bike bags away from that epic ride experience."
