Innovative Battery Technology: Extended Range and Performance
Equipped with a 720Wh battery, the Explorer Peak ensures a large range and balanced ride, and for those seeking more, an 835Wh battery upgrade is available at checkout. Using new battery cell technology, Explorer Peak batteries provide even greater energy density without increasing size.
Modern Luxuries for a Better Ride
Stay in control with the new integrated top tube display, providing essential information at a glance. The internal noise-canceling design prevents cable rattle, and integrated rubber chainstay protectors reduce chain slap noise, ensuring a smooth and quiet ride. UDH derailleur hanger makes for easy service and is compatible with Transmission drivetrains.
Don’t Stop Riding When the Season Changes
The Explorer Peak is not just a bike, it's an adventure machine for all seasons. Each build option comes equipped with the essentials including powerful 4-piston brakes, 1x drivetrains, and robust tubeless-ready wheels and tires.
Go ahead, take it for a spin.
Size Specific Geo
The Wire Peak geometry is not built around one size and then shrunk or enlarged for each size like most bikes on the market. Instead, each actual angle is adjusted on each frame size to give the same effective angle.

Customer Reviews
I got the bike with the plan for winter to set track faster.,Steeper and further. We'll so far it's been a great bike for that. I also use it to clear downfalls on trails with my Saws. Unstoppable Steed surefooted steed!.
So so much fun! I’ve ridden a regular fattie for years, but the eFattie brings the speed and distance back into the experience. Further, faster, funner. And the Explorer Peak is dialed in just right. Solid ascents and perfect geometry for descending. Love this thing.
I got my Explorer Peak at the end of August 2024. I did a number of rides (250+ miles worth) on the dirt just to get it warmed up for Winter. I took this bike up trails I never would have attempted on my Delano Peak, mostly 'cuz I'm old (72) and a bit fat. I could not believe the abilities of this bike. I'm glad I ordered it with the Manitu suspension fork for some of those rocky downhills up Payson Canyon.
In the snow this thing is a beast. I'm amazed at how well it plows through 6 inches of fresh snow. I'm going to really enjoy this bike this winter.
This bike is so aptly named. It has literally become my exploring bike. I can't recommend it enough.
Have had an absolute blast with the Explorer Peak with all the different assist modes and its versatility. This bike is the new favorite in the lineup now.
