E3 Peak
MSRP: $3250.0

The E3 Peak Electric Bike is a trailblazer in all senses. This isn’t last years commuter model fitted with a big fork and knobby tires; we engineered the Peak from the ground up around the only drive technology that makes sense on a mountain bike (hint: it’s not a hub motor). We spent months tweaking the software so it rides just right, then we rode it hundreds of miles just to make sure. We’re sure. This is a bike to be ridden on the back trails and to the high peaks—the ones that were always a bit too far away before. And with a 28+ mph assisted top speed, you might as well ride it to the trailhead, too.

Our 48V centerdrive motor is the right tool for the job. Hub motors are great on the road, but when it gets really hairy—and really steep—they just don’t measure up. Where hubs compromise, centerdrives excel. Easy maintenance: when you get a flat on the trail, you’ll thank us for using a quick release rear wheel. Downtube-mounted battery: who puts a rack on a mountain bike? Real engineering: we built it to be what it is—and only that. Quality component spec: A Rockshox fork, 650b wheels and hydraulic braking mean you can ride it as hard as you want.
