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.

Cute but disappointing
Color: C-Navy+Oak, Color: C-Navy+Oak
One of my dogs love these however they are far from indestructible. Two days after giving the teddy to him, the tail of the teddy is off and there is a rip by one of the arms. They are very cute teddies but not for heavy chewers as they will only last a few days.

Nothing is indestructible
Color: D-Purple
Adorable. Looks just like the photo. My 15# JRT loves it! however the tail and one ear were gone in a matter of minutes. It’s his toy so I’m just monitoring his time with it as it’s his favorite 😍

Our Pit Bull’s Favorite Toy!
Color: A-Navy, Color: A-Navy
We absolutely love this MAXBECK bear toy! We’ve ordered it 4 times over the last 8 months because our senior pit bull is obsessed with his “babies.” He always has one close to him and even cuddles with them. The material is very sturdy and holds up amazingly well even with rough play. My dog’s favorite part is the squeaker. What I love most is that even after he finally tears into it, the rope built inside becomes a whole second toy for him and keeps the fun going. If you have a heavy chewer who destroys toys quickly, this one is definitely worth trying!

Not indestructible
Color: C-Navy+Oak, Color: C-Navy+Oak
I assume it is probably hard to create an indestructible product, but my puppy had it apart in no time.

NOT DURABLE, LONG-LASTING, OR USEFUL
Color: A-Navy, Color: A-Navy
I gave this dog toy 2-stars based on my dog toy rating system (DTRS) for “Albert” the Blue Bear! Safety (1-rating): Albert fell apart after 4-hours of use. 1. The ears were chewed off and I was only able to find one of them, which means my dog swallowed the other ear. Very big concern as it depends on how big your dog is to pass this object. The ear is about the size of 1.5-quarters. 2. The tail was almost chewed off entirely and was hanging on by a thread before I threw it out. 3. After the ears came off, the inside foam started to come out, which raised my concern for my dog’s saftey. 4. The entire body was soft and did not cause any harm to teeth, gums, paws, nose, etc. Durability (3-rating): 1. The ears and tail are the weakest parts of Albert as they can easily be chewed off. 2. The body is durable enough to sustain 4-hours of use, as I threw Albert out after the ears and tail were torn off within 4-hours. 3. The small squeaker inside Albert’s belly was broken after 15-minutes of use. Thank Goodness! 4. My next concern was how long the arms and legs would last; TBD! Squeaker (1-rating): 1. Small plastic squeaker, the size of a half-dollar, with a high pitched noise. Fatality (2-rating): 1. Albert was put to rest after 4-hours of use as I was concerned for the safety of my dog with continued use. 2. If Albert didn’t come with ears or a tail, I can only imagine how long he would’ve survived as the material seemed to be durable enough to withstand continued use. In conclusion, “Albert” the Blue Bear is not worth the money for a toy that falls apart after 4-hrs of use and with the concerns of safety. I was surprised that it was only 8-inches tall, next time I’ll confirm the size of the toy before I purchase the next one. About my dog “Cannoli” for comparison: Breed: Blue Healer / Lab mix Weight: 40-lbs Energy Level: High Age: 7-months Chew Rating: Aggressive
