The RMU NIGHTTRAIN

At RMU we wanted to match our boutique manufacturing passion with our obsession for Mountain Biking.  Our intent was to produce a highly sophisticated small batch (seriously there's not alot of them!) aluminum production for core riders who are dedicated to the mountain lifestyle.  So we designed the NIGHTTRAIN in partnership with Dave Weagle using his Orion Dynamics platform and dual idler layout.  The NIGHTTRAIN is a full Alloy, no compromise enduro bike that is made for the roughest of terrain to the biggest of jumps, while also being extremely efficient climbing uphill. The bike is designed to pedal very efficiently all while encouraging you to pump, jump and play around on the trail. The NIGHTTRAIN takes from our ski design philosophy at RMU of creating some of the most fun, playful, and versatile skis on the market and brings that to the Bike world.

The RMU NIGHTTRAIN is built for riders who want a true freeride/enduro crossover machine capable of handling everything from bike park laps to aggressive backcountry descents. Designed as a long-travel 29er freeride bike, the NIGHTTRAIN combines 170mm of travel with innovative mid-pivot suspension and Dave Weagle’s Orion suspension platform to deliver exceptional traction, control, and support at speed. Its unique dual idler drivetrain and two-chain drivetrain system help reduce pedal feedback while improving suspension performance through rough terrain. Built from durable aluminum, the NIGHTTRAIN stands apart from traditional alloy mountain bikes by blending playful freeride mountain bike characteristics with the efficiency and capability expected from a modern enduro mountain bike.


TRAVEL FRONT: 170MM
TRAVEL REAR: 170MM

The RMU NIGHTTRAIN 170mm isn’t just a mountain bike; it’s a statement of intent. As part of the ultra-limited production this "Midnight Onyx" edition represents the pinnacle of Rocky Mountain Underground’s engineering and aesthetic philosophy. The NIGHTTRAIN is designed for those who treat the descent as a canvas and the climb as a necessary ritual. The NIGHTTRAIN is a long-travel enduro machine that defies the sluggish stereotypes of its class.

Key Highlights

  • Size Specific Geometry and Kinematics: We designed the NIGHTTRAIN with size specific geometry and kinematics. This ensures that whether you're on an S1 or S4, that you are getting a bike tailored for you and the way you ride.

  • Elite Pedigree: A bespoke "Midnight Onyx" finish—a deep, stealth-matte aesthetic complemented by premium hardware and understated branding that whispers rather than screams.

  • 170mm of Pure Confidence: With 170mm of travel, the NIGHTTRAIN is built to swallow rock gardens, huck-to-flats, and steep technical chutes while maintaining a supportive mid-stroke for popping off side hits.

  • Precision Geometry: Engineered for high-speed stability without sacrificing the "flickability" RMU is known for. It features a slack head tube angle for the steeps and a steep seat tube angle to keep you centered during grueling transfers.

  • Aluminum Mastery: The frame utilizes 6066-T6 aluminum frame, optimized for a perfect strength-to-weight ratio.

Walking from Mexico to Canada with a great cast of characters
Format: Paperback
I thoroughly enjoyed reading Journeys North. The story is about the Pacific Crest Trail and the people who hike it (thru-hikers) attempting to walk from Mexico to Canada. The author brings the trail to life across the story, but what really stands out is the story of the characters. You find yourself rooting for them as they encounter all kinds of challenges, and you get to know them through their backstory and past experiences that are shared. People attempt a thru-hike for many different reasons, and the story is enriched by their personal stories and histories that they carry with them each step of the way. Even their “trail names” had stories that often highlighted something about the characters themselves. One of the unique things about the book is the Pacific Crest Trail itself, as the author’s descriptions allow you to imagine what it looked like and felt like (including the aches, pains, and injuries along the way). The trail is ever present across this story of the people who walked it, bring them together, and then pulling them away from one other, sometimes for weeks or even months. The trail and mother nature create for an everchanging backdrop as the characters navigate their way north. I am not a thru-hiker and I doubt I would ever attempt to walk from Mexico to Canada, but I enjoyed tagging along on the adventure of Scout, Frodo, Blazer, Dalton, Tony, Nadine and many others whose lives intersected over the course of many miles. I found myself having a hard time putting the book down, particularly as the hikers neared the Canadian border. If you are looking for an armchair adventure along the PCT, or wondered what it would be like to tackle a thru-hike of a long trail, or are curious about the people who undertake such a challenge, you will enjoy Journeys North! I would imagine that if you are a PCT hiker you would find the book even more meaningful.

Incredible Life experience while hiking the PCT
Format: Paperback
As I began experiencing great stories about the "Camino" pilgrimage in Spain, books about "thru hikes" in the US seemed to find me too i.e. The Pacific Crest Trail, and did grab my attention for various reasons... "Journeys North"-- To me, this story makes it more than apparent, that if you want to learn about yourself and open your "vault doors" so to speak, and free yourself of personal challenges-hiking the PCT could help. This book on it's own, is a wonderful treatise about the PCT, and taught me much about being open and honest with others to include oneself, and about being grateful." This story "rings" of Freedom, is intense, and at times, raw. From the comfort of my living room... Frodo, Scout, Blazer, and company drug this old backpacker (me) a.k.a. "LightningLayne" along on a fantastic journey north clear from Mexico's northern border to Canada's southern one. Along the way, I noticed how the "goodness" in people replaces just about every negative the world throws in your face. Finally, I laughed, I cried, and even felt sorry at times for all the "participants." In the end, I was "grateful" for the individual and collective stories shared. This story is one that has burrowed in deep and is one I will never forget.

A community 3 feet wide and 2650 miles long
Format: Paperback
One of the aspects of long-distance backpacking on our National Scenic Trails that those who haven't done so are generally unaware of is the tight-knit sense of community that binds hikers together, even hikers who've never met. These folks are average people with a vast range of life experiences and circumstances, and not simply a generic array of "professional hikers" involved in some sort of athletic competition. In the "real world," you can know someone for years without *really* knowing them at all, but on the trail, a single day can feel like weeks, and months can feel like years. You can bump into someone in the morning, and have a new "old friend," soulmate, or savior by the end of the day. In "Journeys North," Scout brings this community to life on the page vividly and emotionally, drawing us into not just his own life and experience, but of many others in his trail family- all making that journey north in a literal way collectively, as well as in their own personal ways figuratively. Along the way, he relates the highs and the lows of not just life on the trail, but of life in the "real world" as well. It's a crash course in empathy, determination, and sometimes just plain stubbornness. When I received the book and flipped through it quickly, I was at first surprised at the lack of photos- just a single page at the end with a handful of shots of the "main characters." But as I read the book, I quickly realized that Scout's richly descriptive prose paints a far better picture than any actual pictures could, and was grateful for the space he made for my imagination to play a part in his story. While no book could ever substitute for the actual experience of hiking a long trail, "Journeys North" serves as great inspiration for those who aspire to, as well as reassurance for their friends and family that they won't simply be disappearing into the wilderness alone.
