Press Release: Mossy Cog Designs

Mossy Cog Designs announces the Tight Stack Bike Rack, a wall-mounted rack designed to save you space. Whether you personally have a full quiver of bikes or a bike for each member of the family, our rack will pack them in tightly, freeing up precious space in your garage, shop, or storage area.

Mossy Cog Designs, based in the Pacific Northwest, was founded out of necessity thanks to our serious mountain bike addiction. At one point in time, each company member's small Seattle condo was overrun with bikes, leaving little space for anything else, and we knew it was time for a change. Unimpressed with the selection of wall-mounted racks at the time, we knew we could leverage our 20+ years of collective design and manufacturing experience to create a rack that would solve our storage issues.

We set to work, teaming up with our prior fabrication shop contacts to keep the custom manufacturing local and in the hands of people we know and trust, and thus the Tight Stack Bike Rack (TS-4) was born. We’re proud to say that our products are designed, fabricated, and assembled locally in the PNW.

Easy access to load or unload. All bikes stay in the rack, with no tangling of bars and cables.

While solutions exist for hanging 1 or 2 bikes, it’s difficult to find options that store multiple mountain bikes in a clean and functional way. Our patent-pending swing and swivel action on the TS-4 allows 4 bikes to nest close together and makes removing any one of them a breeze. Gone are the days of shuffling bikes around the garage just to get to the one you want. Simply flip through your bikes on the wall like you’re back in your youth searching through your favorite binder of old CD’s on a road trip, straighten out your handlebars, and pull your bike of choice from the wall.

TS-4 rack mounted.
TS-4 rack with a Plus1 Extension.

The base model rack can accommodate standard full-size wheels (26”, 27.5”, 29”, 650B, 700C), and adjustable length support arms are available to hold bikes with wheels as small as 16”. Single bike extensions can also be purchased and added to each end, meaning the rack can accommodate up to 6 bikes.

Adjustable arms make it easy to keep all of the family bikes in one place.
Made to be used. Made to last. Made in the USA

Why This Rack

The Tight Stack Bike Rack was designed to accomplish 2 goals: to take up as little space as possible and to allow easy access to any bike without needing to remove any others.

We found vertical mounting to be the best option for storing more than two bikes in a limited area. With any wall-mounted solution, the rack needs to be secured into a stud. While this limits individually mounted racks to a minimum spacing of 16” based on standard spacing of 2x4 studs in home construction, the TS-4 uses a single mounting plate to allow the bikes to sit just 12" apart. Rotating the handlebars ensures they don't overlap and the ability to page through the bikes means any rack position can have unobstructed access to store or retrieve your bike.

Rack Specs

Weight Limit:
50 lbs (22.5 kg) per bike
175 lbs (80 kg) per rack

 I put 3 of those along a 5 foot 2x4 and sat it on top of two rafters in the garage and it's great.

 I've tried several vertical hanging options including these books and none work well for several bikes unless you have the room to space them apart 30+" to keep the bars from tangling. This e would solve all of the issues I've had with other systems. I'll be trying this one as soon as he comes out with a fat bike adapter.

 Just flip every other bike and you can space them at 12 inches easily. @gilby82:
  • 15 17
 @GBoyd: Yeah, nope. Not when you're dealing with everything from Large 29ers, to 20" kids bikes with dirt jumpers and a fat bike thrown in. I've tried upside down. I've tried hooks at different levels. It's all a pain in the a$$. The only other option I've seen that has some of the benefits of this system is the Steady racks, which are $90 per bike and still don't allow you to pack bikes in this tight.

 the rubber on those hooks wore through and starting scratching my rims, so I put some old grips over them but then they tore off my rim decals over time

 @gilby82: correct. If you ride different styles of bike and/or have kids, the $5 hooks are bullshit. You'll never find a pattern that prevents the bikes from either a) hanging up on pedals and bars as you take them out or put them away, or b) eats up 36" of horizontal space per bike. Every time I try to pull my BMX out from between the other bikes I tear up bar wrap or paint jobs with the pedal pins.
  • 17 3
 We've tried the hooks before as I'm sure most have. Works great for 1 or 2 bikes...until they start scratching up and damaging your rims. Yeah you can stagger the hooks and try to pack your bikes in as close as you can, and maybe somebody has figured out the perfect set up and we haven't seen it. Unfortunately in our experience, getting bikes in and out of tightly packed hooks results in a not very fun game of Bike Tetris where expensive bikes end up scratched. The TS4 packs the bikes in tighter to each other without scratching anything, it keeps the bikes closer to the wall to save space, it takes up less space down the length of the wall, and it makes popping bikes off the wall headache free.

 @gilby82: I just put up a plank of wood with tire hooks in my bike room. 6 bikes, 35cm (14") apart, alternating front and rear wheel up with a DH bike, 2 trail bikes, 2 dirt jump bikes (hanging from the rear wheel), and a road bike (also from the rear wheel). 0 issues with bars getting tangled, cost 35 minutes of my time, and was free (at least for me). I will admit, once the rubber rubs off the hooks the rims will get scuffed, but no worse than rocks pinging off your rims.

 @PinkBikeWhisperer: that's pretty sweet if you're looking for ceiling-hanging storage. Unfortunately the only place I have in my garage is right next to the garage door so I can't have anything hanging from the ceiling or give up use of that garage door. I'd like to see anyone hang more bikes of mixed sizes in a smaller horizontal space and have easy in/out for all bikes. Anyone that says to turn bikes over is ignoring the fact that different sized bikes will still hit and it's a P.I.T.A to flip a bike upside down to hang out vs. just rolling them in on the back wheel. To each their own. I'll gladly give my money to this US company for solving a problem I've been dealing with for years. If someone posts a video of their Lowes-hook version that proves to hold as many bikes in as small of space and is easier to get them in and out, I'll gladly give them my money instead, but I doubt it will happen.

 @PinkBikeWhisperer: I did a similar rack a few years ago using inline skate bearings and dowel rod with spacers to keep the bearings in the track of the Uni Strut. FYI, you can also get nice machine thread hangers from Park Tool.
Uni Strut here for way less than Amazn.
Sorry, I don't have links for the other parts I used. I can dig them up if there is interest. I'm actually in a different house now, and considering building the rack again.

  • 1 0
 @PinkBikeWhisperer: I made a similar rack with the same metal track, but instead of hooks, I used Husky velcro straps (can't remember the length)... it works great. And, being able to rotate the bikes while they are hanging is a huge plus in a tight space.

 @Endurahbrah: If it’s not too much trouble I’d love the rest of the parts list. The setup shown above on youtube seems great, but maybe a bit overkill and expensive for sliding light weight bikes. Thanks!
  • 1 0
 @jdee2wheels: Sorry I don't have the parts list that I thought I had. I used threaded rod for the bearing axles, and cut them to length to fit in the U channel. Then just need a spacer that is the right length for between the bearings. You want the bearings to ride on the ridge of the U channel.

I'm eventually going to make some new ones and design something better, hopefully with off the shelf parts from McMaster Carr or local box store.

I will post more if I ever get around to doing this project.

 @jdee2wheels: Sorry I haven't gotten around to providing a parts list for the system I used years ago. But I did find this from Rockler.
This system looks like it would be perfect, and from my measurements, you could use their trolly's and hooks with standard steel Superstrut found at local home centers. Superstrut is cheaper and stronger than the plastic track Rockler is using.

 Price aside, it looks great. Would love to see something similar available in EU. I use a similar concept to store 5 bikes in my garage, but it takes more space, and the other 3 bikes Wink need to bet tucked elsewhere. Every father of a riding family would appreciate this.

 Maybe my knowledge is 20 years outdated but I heard somewhere once that mtbs with suspension forks shouldn’t be stored in a position where the fork is horizontal or upside down due to leakage concerns. I had an old Manitou fork lose all it’s oil hanging from garage rafters. That can’t be a thing these days, right?
  • 2 0
 @gnarlysipes: We've never ran into issues with fork seals leaking on us from hanging bikes up. Fork seals have only improved over time and most modern forks have a foam ring below the seals that actually get lubricated by hanging/flipping your bike upside down pre-ride. Regular suspension maintenance and replacing worn seals should keep your fork feeling good and leak free as well

 Why do so many people seem to think that these guys are ripping them off? Is it expensive, yeah, but I highly doubt that they are making a massive margin or that the founder is going to retire with millions. No one who starts a small company like this does it for the money.

 So 4 of those is $240 on Amazon. Which is cheaper than $375... But this is integrated and appears to be a better engineered solution, no plastic, etc. As a guy with 6 bikes on the wall and 6 on the floor (4 kids and a wife that rides) I'm interested in getting some garage space back...

 @laksboy: steadyrack. Currently have 6 on the wall in my garage.

 @pcledrew: how do you manage handlebar interference? Mount at different heights and specific locations for specific bikes? Still $280 for 4.

 @pcledrew: The Feedback Velohinge is the same functionality as the steadyrack but a sh*tload cheaper. I have 4 in a row and the hinge is super handy
  • 2 0
 @EnnZed: You couldn't be more wrong.

The Feedback is simply a hook with 90 deg rotation.

SteadyRack is a wheel in tray design, with 180 degree rotation, and the key feature, a no lifting required design.

My kids can vertically load / unload their 20" wheeled bikes into the steadyrack with ease. The same is not true for any hook style bike rack.
  • 1 0
 @pcledrew: Fair enough, a hook is tricky for kids. For adults, a staggered arrangement of the feedback hooks works for me.
  • 1 0
 I can store 8 bikes with removed pedals on a DIY steel pipe bolted to the ceiling, hooks are made with 4mm wide steel rod, with a bit of plastic tube protection.

Silmilar to that design:

I can slide the bikes as well.

 Just put up my SteadyRacks in the “new” garage, but this seems like a better option for a similar price. Maybe this will be my five attempt at storing more than 4 bikes on the wall…

 I'm not very good at maths, but isn't 50Lb/bike x 4 = 200Lbs? Not the 175Lbs they state as the limit. I sure do like these provided you have enough ceiling height.
  • 5 0
 The 50 pound weight limit is for the individual basket. The 175 pound limit is for pulling out of the wall studs, which is why we specified a rack limit. If you don't plan to hang 4 50 pound bikes, this won't come into play.

 Never had problems with headsets until i started hanging the bike, even wiping the fork down before putting away, I guess crud just leaches in there

 Yeah I've always been a floorack guy for that reason. Bigger footprint obviously so a different use case then what looks like a well made solution to the more-bikes-then-space problem these guys are solving. My garage is full-time gear shed / work shop and for $50 I get the bike shop look, easy access, and no leakage -

  • 1 0
 @Quinn-39 We have thrown multiple road bikes into the rack. I currently have a road bike in my rack at home right now. With a single drop bar bike, I'd recommend putting it in one of the end positions where it will be nested in front. For multiple road bikes it works best to keep them next to each other, also to the front of the rack.

Working on setting up selling to Canada ASAP

 Unfortunately, manufacturing costs drop with volume. As a small company just getting started, our volume is low.

Keeping manufacturing local does raise the price of the rack a bit. Trying to do our part (however small it may be) to keep shops and businesses in our community afloat just seems like the right thing to do with everything that’s going on in the world.
