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.

Liked so much, I bought TWICE!
Color: 23 - Ice Blue, Size: Twin
These sheets are such a great quality for the price. They feel soft and comfortable right out of the package and make the bed feel so much more cozy. I’ve washed them multiple times and they still feel great with no fading or pilling. The fit is also excellent — the fitted sheet stays securely in place and doesn’t slide off the corners during the night. I was so happy with the comfort and overall quality that I ended up purchasing a second set. Definitely worth the money and I would highly recommend them to anyone looking for comfortable, well-fitting sheets at a great price.

Finally we BOTH can sleep comfy!
Color: 08 - Black, Size: Queen
So for years my boyfriend has always liked “jersey sheets” or “tee shirt” sheets or sheets made of flannel. He says he doesn’t like the feeling of cold “silky” feeling sheets as he’s always cold. I’m opposite and am always hot, and anytime we stayed in a nice hotel I looked forward to being able to sleep on cooler, taught, soft sheets for a couple of nights. I was able to deal with our old sheets but the issue we both hated was after awhile any sheet we got would get pilling. We even splurged and got a $60 flannel sheet which did the same thing forcing me to shave off these little annoying fuzz balls that make it feels like there is thousands of crumbs on the sheets. I also would wash our bedding once a week because the Jersey sheets seemed to “grow” as we move around in bed making it so the sheet was not taught and super annoying to lay on. The day I would wash them they would be comfortable but ultimately by the end of the week they would be almost hanging off our mattress. I ordered these sheets on a whim and got them the same day and immediately just threw out the jersey sheet and put this on (I didn’t even wash it, I know it’s gross but I was desperate for a comfy nights sleep and they came around 8pm) when I put them on I realized how soft and comfortable they felt. I also liked how the pillow cases are larger than most pillow cases that I have had in the past. We’ve been using these sheets for about a week and I love how I don’t wake up with my pillow popping out of the case anymore. The sheets have loosed ever so slightly since a week of sleeping but still are really taught and comfortable. They are cooler than flannel or fabric sheets and are initially cold when you first lay on them but I wouldn’t consider them “cooling” but they keep me from feeing extremely hot. They are way better than I ever would have expected for the price. I look forward to laying on them at the end of each day, even my boyfriend laid in bed the day I got them and said “wow I didn’t think I would like sheets like this, these are so soft!” And fell asleep immediately. We ended up ordering a second set in grey and the color is pretty. I still have yet to wash them, I usually use 2 tide pods when washing the bedding but I might get some fabric softener (as I hear it helps with pilling) to prevent the possibility of having that happen to these sheets in the future. I am hoping they hold up well after the wash and longer use. If they start to pill after wash, I will come back and update my review. Until then, I would highly recommend these sheets for the quality and the price point that they are offered at. Honestly, at this point even if they pill months from now I probably wouldn’t even be upset as long as they stay the same price I would just buy another set as they are just that comfortable and soft. UPDATE: So it has been about 3 months since I have purchase and used these sheets. They are still as soft as the day I first put them on. I’ve been washing them bi-weekly along with my comforter and pillowcases. I wash them with warm water using a combination of tide pods and added Downy fabric softener. They say to hang dry them in the description but I have been putting them in the dryer on medium and have been taking them out after around 20-25 minutes, they seem to dry extremely quickly. They have yet to have absolutely any pilling and also have not shrunk or stretched. Also I have a cat that is very active and also sleeps with me who enjoys kneading on my bed and I haven’t even noticed any signs of wear what so ever to the eye or to the feel. I highly recommend these sheets. I still have yet to even open the second set I purchased!

Amazing quality for the price! So fresh and lightweight
Color: 03 - Light Grey, Size: Queen
I am very impressed with this queen sheet set! I originally bought it because of the great price, but the quality has exceeded my expectations. The fabric is incredibly soft, lightweight, and stays very fresh throughout the night. It truly gives you that comfortable hotel bedding feel without breaking the bank. If you are looking for breathable and budget-friendly sheets, I highly recommend this set

Utopia bedding is GREAT
Color: 15 - Sage Green, Size: King
I had never heard of Utopia before I suddenly needed to buy bedding for my adult autistic son. He has sensory issues so shopping for anything that touches his body is a bit of a nightmare. I took a gamble on these sheets but it paid off big time! He says they are the most comfortable sheets he has ever slept on and that he doesn't overheat sleeping in them. What I liked about them is that the pockets were deep enough that it fit on his oversized plush mattress easily. I love the color and the ones I bought were very true to the picture. These are soft, comfy, they look nice and they are affordable. I liked this brand so much that I went ahead and got pillows and a comforter from them as well. Its is great for my son and I am very pleased to have found a fabric he tolerates.

For soft, sensually awesome sheets- LOOK no more!
Color: 15 - Sage Green, Size: Full
Would give 10 stars if possible! (And this is a nonpaid for review!) When I received the sheets, instantly I knew that I had the right ones, had bought a down comforter close in color as well.. these sheets? The material is strong yet, soft and warm. So so especially soft, and when I make up the bed, ahhh! plus the corners on the fitted, such a cinch to pull over the mattress, even with a topper on the bed! Feels almost spa-like <3 Very comfy, so far in the winter and in 85 degree heat! Soft and easy peasy to care for, too. Washing is a breeze, dry and fold. So far the only thing I can smell on these sheets is my wonderful detergent! Will purchase again. And possibly, again! Thank you!!
