Niner WFO e9 3-Star SRAM SX Eagle E-Bike: You’re free. Free to pedal instead of shuttle. Free to roam, explore, and ride whatever you want, whenever you want, with nothing holding you back other than your imagination.

Your access to the rowdiest terrain, steep backcountry lines, and local chunder just got a lot better. With aggressive geometry, 180mm suspension travel, a coil spring, 29” front wheel / 27.5” rear wheel, and Bosch Performance Line CX drive system, the WFO e9 is ready to punch your ticket to the top of any trail and capably carve its way down.

180mm suspension travel: a remarkably supple, balanced suspension curve riding on a coil spring, ready to tackle the toughest terrain.

Welded 6061 aluminum frame and one-piece motor mount: unifies the upper and lower pivot locations with the shock mount for exceptional stiffness. Forged seat- and chainstay yokes, rocker arm, hollowed dropouts, plus our signature Enduro Max Black Oxide pivot bearings, make this all-new Niner chassis rock solid.

Bosch Performance Line CX motor: delivers smooth pedal assist with no surprises. Torque sensitive, zero-lag power delivery is predictable in all conditions. And the 625wh battery means you can ride farther without fear of losing the juice.

29er front/27.5+ rear wheel setup: The smaller rear wheel keeps the chainstays short for snappy trail manners and offers up massive traction.

Niner x Bosch
Our new e9 series of ebikes is powered exclusively by Bosch, a global leader in ebike technology. The Bosch Performance Line CX is the best choice for Niner’s e9 series.

• Bosch’s latest Performance Line CX Gen 4 motor is smaller by 40% and reduced in weight by 700 grams (26%) while increasing efficiency (more range for the same battery) and keeping the torque performance, compared to the prior version.
• Bosch’s motor is the most efficient on the market today with the flattest torque curve. This means that at any cadence between 30-110rpm the torque is even and available to the rider.
• Bosch has the most responsive (fastest processing speed) torque sensor on the market. It’s 20x faster than the nearest competitor. This means the system adds assistance faster and also shuts off faster when the rider stops pedaling.
• Bosch’s battery is the only UL listed battery and charger on the market. We are using Bosch’s new PowerTube battery in the 625 Wh size, integrated seamlessly into the frame to optimize low center of gravity.
