Paketa Magnesium Bicycles

Our mission is to build lightweight, high-performance bikes that ride better than any other bike on the market.  We believe that magnesium is the best bike frame material available, and after you ride a Paketa, you will too. We custom build our road, mountain, and tandem bicycles right here at our shop near Denver, Colorado. Please email us if you will be in the Denver or Boulder area and would like to test ride any of our bikes including the famous V2 and V2r racing tandem bicycles.
All Paketa bicycle frames are built with custom geometry for a guaranteed fit.  We work closely with you to build you the tandem, road, or mountain bike of your dreams.

 2013 Nationals: Paketa team riders and racers brought in lots of medals at the US Masters Nationals Road Race. Congratulations to all of our team riders including Dave Walker and Terry Malouf, the entire Radsport Team, Henry Abel, and more. Thank you all for your continued support.

I want to personally thank you both for an incredible opportunity & phenomenal memories. The Paketa was so fast; so much fun to race. And, as a result of having such superior equipment, Steve and I flew through that TT course at Master’s Nationals, winning a gold medal. That will always be an epic event in my life!  — Beth Graff – Gold Medalist, US Master’s National Championships, Mixed Tandem 110+ Time Trial

 

Designed and crafted entirely in the USA

 

Paketa Cycles have been based in Boulder, Colorado, since the company’s birth in 2001. Boulder’s rich cycling heritage and extensive depth of both riders and technical cycling experts makes it the ideal place for us to design and test our proprietary extruded- and TIG-welded magnesium frames. The last two years have been all about testing, refining and delivering the first truly available magnesium bikes in the world. It wasn’t an easy road, but we never thought trying to revolutionize what bikes are made of, and exactly how to do that, would be. Why go to all the trouble? Well, when you try a Paketa, you’ll see for yourself. Riding is believing!

We invite you to “step outside of the box” and see just how much better a Paketa is than any other bike in the world. That’s a bold statement, we know, but we aren’t about being subtle. If you value ride quality as much as light weight and good looks, magnesium will force you to re-evaluate what bicycle frames should be made of.

 The next step is getting you on our bikes . Let us know what we need to do to make that happen so you too can “Ride the Revolution!”

Paketa Custom Colors

Choose one, two, three, or four color custom paint jobs
 Paketa Cycles believes in providing you with the exact bike you want. That’s why each frame comes with fully custom geometry, components, and even paint job. The boundaries are endless to what you can make your bike look like. We will work with you through each step to make sure we make the bike look good. Choose from simple sharp looking one color paint jobs, two color fades, or multi-color custom designs.
  •  STEP 1: Choose number of colors. prices vary
  •  STEP 2: Choose color or colors
  •  STEP 3: Discuss options with Paketa sales manager
  •  STEP 4: We will do a digital mock up of the design and submit to you for review. see samples below.
  •  STEP 5: Adjust design until it looks like your dream bike. (more than three changes in digital design will incur extra fees)

Corrosion

Magnesium does not carry an increased risk of corrosion.
Magnesium bicycle frame care

 Paketa has had almost no bikes returned with signs of corrosion since we began building bikes back in 2001. It’s true that bare magnesium can corrode, just like steel and some aluminum alloys, but a properly coated and cared for Magnesium frame will not have a higher chance of corroding than other materials. To test the corrosion potential of a magnesium bike, we built up a demo bike that was completely unpainted, bare magnesium. JP, the owner and framebuilder, has been riding this bike to work everyday for 3 years with no signs of corrosion.
rocket unpainted
This frame has been on the road for three years. No paint, no coating of any kind, and no corrosion whatsoever. During the three years, it has been ridden in rain and snow, and left out in the rain a couple of times. Even in those conditions, no corrosion. Magnesium that is bare can corrode, so we powder coat or paint all of our frames and coat the inside of the frame with CorrosionX. We use these precautions to make sure our customers don’t have corrosion issues. Paketa riders can also take extra care of their bike to make sure it doesn’t happen. First of all, keep your bike inside and dry. If you ride in the rain, make sure no water is sitting inside the frame. This simple care is congruent for all types of bikes. Second, spray Framesaver or Corrosion X inside the frame once a year just as you would a steel frame.  In general you don’t need to be concerned with corrosion, and following these simple care guidelines will keep your frame free of corrosion for years to come.
 Care Guidelines: Follow these guidelines to help your custom Paketa Bike frame last many many years.
  • keep your bike inside and dry. towel dry to remove water or sweat.
  • hang your bike upside down with the seatpost removed regularly, or after contact with water or lot’s of sweat.
  • spray corrosionX or framesaver inside the frame regularly. Tilt the frame around in different directions to allow the fluid to coa the inside.
  • ANNUAL – we recommend removing the crank and bottom bracket once a season. With the bottom bracket removed, you can spray corrosionX inside the tubes through the holes into the BBshell. It is also good for the BB shell to be cleaned and re-greased for insertion of the bottom bracket. This is also a good time to replace your bottom bracket cups.
  • Use auto touch-up paint to seal any scratches or chips in the powder coating.
  • Examine your frame after every ride for damage of any kind.

What do people think?

What do people think about the Paketa V2 Tandem?

A note from Dave Walker, Tandem enthusiast, guru, and designer of the V2:

I’ve been riding, designing, and tinkering with tandems for nearly 20 years and have logged over 200,000 km on them in that time. I love cycling of all types, but tandems are the heart of my passion. One of the nice things about the Paketa V2 design is that standover height, either front or rear, is almost never an issue. It really comes down to getting the right captain top tube length; thus, the three (stock) frame sizes offered of 54, 56, and 58 cm effective (i.e., measured horizontally) captain top tube lengths.

Stoker top tube length is the same on all frames; proper fit is achieved with the correct (often times, adjustable-length) stoker stem. It’s that simple.

As for comfort vs. stiffness, there’s a few things I can tell you about that. What sets the V2 apart from all other tandems on the market is the very high ratio of stiffness to weight without producing a harsh ride. First and foremost is realizing that the material properties of magnesium (Mg) afford a vibration-damping capacity that is about an order of magnitude (that is, 10X) better than steel, aluminum, or titanium (which are all comparable, by the way). Thus, it’s not just a marketing gimmick: ten times better vibration damping is enough that even casual “weekend warrior” riders can feel the difference. Comparing Mg to carbon fiber (CF) is a bit more difficult because the stiffness, weight, and vibration-damping characteristics of CF are highly dependent on how the material is used: lay-up, tube size/configuration, etc. But, I’ve ridden a number of CF tandems, and while they’re not bad, for my money the Mg produces a better ride while still having that resilient feel of a fine metal frame without any weight penalty.

On a personal note, over 1/2 of those 200,000+ km I’ve put on tandems in the past 20 years were on a Cannondale aluminum road model. Compared to the C’dale, well, to put it simply, there is no comparison: the Paketa is way lighter, just as stiff, and much more comfortable. Interestingly enough, most people who try a Paketa tandem for the first time comment first on the exceptional ride quality and then on the lively, predictable handling. Light weight is obviously good for hill-climbing (and we certainly appreciate that here in Colorado, too), but as a practical matter it comes in handy more often than you realize. My own V2 is right at 11 kg and is the first tandem (out of 20+) we’ve owned that my wife can lift onto a conventional car roof rack by herself, with ease–it’s actually lighter than her own full-suspension titanium mountain bike! Living with the bike, day in and day out, is truly a joy.

-Dave Walker


My wife and I have been riding tandems since 1985, and over the years have owned 10 different tandems.   The Paketa was a revelation.   Riding a bike this light makes acceleration a delight, and also makes climbing so much more fun.    We were hoping for these traits and we got them.   But the real surprise came with the wonderful combination of stiffness  and compliance.  The Paketa is stiff  enough to allow easy stands for both of us on steep ascents, and pleasantly compliant enough for the stoker on rough roads.

I just received my new Paketa Magnesium bike and it simply rules! The characteristics of Mg are that of carbon, titanium, steel and aluminum materials rolled into one super light bike. It has the dampening qualities of Carbon but doesn’t feel dead; it has the comfort of titanium and steel but is way lighter and it has the agility of aluminum but stronger (due to thicker tube walls). Paketa did a beautiful thing. I just thought I would pass along to fellow cyclists. Later, I’m heading out and doing a century.

I’ve already had several unsolicited inquiries on the road from cyclists about how I like the magnesium- during training rides, and again yesterday, while warming up for a crit at the State Patrol venue in Golden. I always tell them the same thing…that the bikes are everything positive that they may have heard about, only more so!

After my first race on it yesterday, I am even happier with the Paketa than I was before. It raced stiff and lively, snappy, but very precisely controllable.  It gave me a great deal of confidence on the course.  Bottom line-I am extremely proud to be racing on a Paketa, and I’m sure everyone else on RMRC feels the same way.

We’ll keep passing the good word!

Cheers, Jeff Hammond Rocky Mountain Road Club

 


Hi Dave

We love the tandem;  it’s very responsive on the hills. Thanks!

Greg Rancourt

 


Good Morning Nick,

The team sent the three tandems to the State TT Championships this weekend and came home with two gold and a silver.  Dave’s bike (the large) set the fastest time overall.  They are smokin’ bikes!  We all agreed that compared to the Calfee and Santana tandems we used last year, the Paketas are off the chart.  They turn great, barely flex and are so comfortable, even in a TT position that it made the effort a lot less painful than last year.  See the photos.  When we get our State jerseys we will shoot some more photos for you that you may want to use in your advertising.  A lot of people are noticing and asking about the bikes.  We’re hoping to generate some sales for you.

Bruce


Well we took our new V2 for her maiden ride yesterday evening. What a ride!   The wind was blowing well over 20mph and our first 9 miles were straight into it! The bike handled flawlessly, I was used to being worn out from holding up our old tandem in such a wind but this one just cut right through it. We made the turn at 15 mph average and then the fun really began!  Talk about responsive!  I wanted to not only hammer into the wind but I wanted to set her sail with the wind, believe me, it did not disappoint us…We finished strong and the bike rode tremendously well on rough pavement, it just absorbed it and when we smashed those wonderful pedals, it almost jumped out from under us! (Not once did my feet go numb from the pressure with these pedals) woohoo!
The fit of the bike is wonderful…It feels like I am on my single and it handles on a rail…What is really cool is when my stoker moves around to drink or speak to the people as we zooom by them, the bike does not waver as our old tandem did….( my shoulders love that)”

-Barry

 


Hi Nick,

I thought I would send you a picture of the white tandem built up.  We have been riding it for 5 weeks and it’s been a great ride.  We couldn’t be happier with the performance.  Very light and stiff.  We look forward to taking it to Nationals again this year.  The first stop is our first State Championship race the end of the month.  We’ll keep you posted and send you results.  There will be three Paketa tandems in that race thanks to you guys!

Thanks so much for your support,
David Prechtl

First ride: Very smooth!  My wife and I both thought this was the smoothest bike we have ever ridden. Not to mention fast! We got up to 32mph without digging deep at all. Cruising around at 22-23mph at a “base” or “fat burner”effort. We’re very pleased with the bike. It’s about 23.5 lbs with pedals and cages. We will drop a small amount of weight when we change stems (“fitting” stems on there now), and change to lighter stoker stubs.

Stronger Than Carbon Fiber and Aluminum

Magnesium is the finest bicycle tubing material out there.
Stronger Than Carbon Fiber and Aluminum

Relative Weight of Magnesium Bicycle Frames

Magnesium is the lightest structural metal currently available in the world. Its approximately 34% lighter by volume than aluminum and 50% lighter than titanium. Besides light-weight construction, a few of the other advantages that magnesium offers are: excellent fatigue resistance, denting and buckling resistance, and the highest known damping capacity of any structural metal. The result is a much smoother ride than any other material out there.

Its no secret amongst the inner sanctum of bicycle fame builders and designers around the world that magnesium could make an amazingly rideable, high-performance bicycle. First, though, a few key issues needed to be overcome: how to extrude the perfect magnesium tubes, weld these tubes correctly, and fine-tune the ride qualities. Following four years of intensive research and lots of hard work on the drawing board and in the shop, we have done just that.

Thickness of Magnesium Bicycle TubingWe are often asked whether Paketa’s magnesium bicycle tubing is a marketing maneuver akin to “scandium” frames, for example, where the material is actually just another aluminum alloy with a small percentage of scandium – or maybe magnesium? The simple answer is, “No!” Paketa’s proprietary bicycle tubing is a carefully chosen material comprising about 92% magnesium, alloyed with other metals to achieve optimal mechanical properties while facilitating the extrusion and welding processes.

Damping is a measure of the rate at which unforced vibration disappears, and is an intrinsic property of the material. Because magnesium has the highest known damping capacity of any structural metal – as much as 10 times greater than steel, titanium, or aluminum – the ride is truly amazing. Vibration from the road literally disappears within the structure of the frame and never reaches the rider. For this same reason, magnesium is used in the high-tech world of aerospace hardware; they have discovered that magnesium offers the best platform on which to mount sensitive electronic equipment, as it is so “quiet”.

Being able to ride longer and with less fatigue are the direct benefits, but the indirect benefits of magnesium might be even more important. Because vibration is not transferred through the frame, the fatigue life is nearly immeasurable. A magnesium bike will keep the exceptional initial ride qualities longer than anything else available on the market today.

 

Many people ask if Magnesium corrodes more easily than other materials. The answer is NO. There is no added risk of corrosion in a Magnesium bike.

Paketa Reviews and Testimonials

What Riders of Paketa Cycles are Saying…
Paketa Reviews and Testimonials “Hello and just a quick note to say we have been on the V2r for a few months now, and we are riding the perfect tandem! This is by far the best tandem we have ridden. Previous tandems owned were a Paketa V2, Calfee, Burley, and we still have a Co-Motion Supremo that is currently idle. The bike is very close to the V2, but it rides closer to a single bike, plus a little lighter with the single bike parts. Visually it is much cleaner with the right side drive. It is very responsive and efficient while pedaling. You don’t feel the internal torque in the bars and across the tires contact patch. The bike is completely stable at any speed and tracks on rails. The smoothness vs stiffness does not make sense, as if they are incompatible with each other, but yet they are both present in the ride. Great job”- Trey

“It [our V2r; dubbed the ‘Hot Tamale’] is the fastest, best handling and most comfortable bike we ride.We now have about 6000 miles, maybe more on the Hot Tamale.” –Chuck & Lisa

“We have been destroying our local fast group ride with the V2r. The Hed H3s and aerobars are a deadly combo. People hate us. We love it!” –Rick & Anne

“My wife and I have been riding performance tandems for 22 years, on nearly a dozen high-end brands [Calfee, CK2, Co-Motion, Santana, Cannondale, Fisher, Teesdale, etc.]. Our new Paketa is hands down the best tandem we have ever ridden. Light, stiff, stable, with a velvety ride. In just the first season with our Paketa, my wife and I set the goal of climbing the top ten paved passes in North America, all here in Colorado. Each pass was a 50 to 120 mile day, and required us to complete a summer season with over 100,000 feet of climbing [both training and the passes]. While we made the choice to get a Paketa not for racing, we found the performance of our Paketa tandem not only made the achievement of our goal possible, this was the most fun year we have ever had riding. The Paketa is a joy to climb with, we were inspired by the bike, and it performed flawlessly!” — Andy

I want to personally thank you both for an incredible opportunity & phenomenal memories. The Paketa was so fast; so much fun to race. And, as a result of having such superior equipment, Steve and I flew through that TT course at Master’s Nationals, winning a gold medal. That will always be an epic event in my life!  — Beth Graff – Gold Medalist, US Master’s National Championships, Mixed Tandem 110+ Time Trial

Well it’s truly our pleasure to ride the V2  because we think the bike is a remarkable piece of engineering & use of a VERY misunderstood/underappreciated material.  The combination of magnesium with the Topolino wheels produces what I believe is an unparalleled ride-ability with all the correct characteristics (lively, vibration damping, stiff, responsive …) While the old saw that “it’s the motor(s), not the bike” is mostly true,  this bike just flat out  DOES make us faster, especially when jumping/sprinting/accelerating & climbing.  We love this bike . — Dan & Dolores Coughlin

So took the Scud out for its inaugural ride Sunday AM.  Have a little 30 mile blast to a local Starbucks and back which I can squeeze in before Church on Sunday mornings.  This bike is ridiculous!!  On all the bad sections of road, where the Litespeed gets “squirmy”, this bike just bombs through like it’s on rails.  It’s cruel that I’m out of town this week.  Can’t wait for ride #2 now that I’ve done some final adjustments to the setup.  Haven’t used the PowerTap yet.  Waiting on a cassette for those wheels. — Hayden

Hey guys, this is Ted Fisher, whom you so awesomely sold one of your bikes last November.  This fall, I was helping a friend replace the pads on his motorcycle brakes in a garage, and he dropped his motorcycle on my Paketa!  My friend was appalled and offered to buy me a new bike.  We lifted the bike off my bike and took a look.  Somehow, it survived unscathed except for a tiny bit of scratched decal on the logo on the downtube (still legible).  Talk about dent resistant!  Anyway, the bike is still treating me well.  I’ve been riding it daily since I bought it, except for about a week when I broke my collarbone June 2006 (and about 3 weeks of riding it one-handed after that).  This winter’s been a true test.  That first big storm on 20 Dec, I could get off the bike and it would stay standing upright! I’m now working at NIST here in Boulder on an atomic gyroscope, and also attending classes at CU.  I try to park it prominently at both (though up at CU I U-lock it and cable lock the wheels). The XT stuff has treated me very well.  I seldom have had to adjust the dérailleurs.  The disks are vital and way easier to deal with than even my old XT v-brakes (which are a huge improvement over non-articulated v-brakes, and cantilevers are right out).  The combo break/shifter levers have never shifted while I was breaking, as the range of motion seems to be separated enough that they’re two independent channels from the same lever.  Also, in a wreck, I’ve found that what would have bent or broken a break lever merely causes a shifted gear.  I have replaced the chain, that dérailleur hanger, and the tires (which I wore smooth, and am running slime tubes due to those accursed goat-head thorn weeds that have infested the area). Everything about that beast of a bike says longevity and performance under harsh treatment.  Thanks again for the hookup, and best of luck getting more of them on and off the road!  — Ted

Hi Dave – We love the tandem;  it’s very responsive on the hills. Thanks!  — Greg Rancourt

Guys – Just wanted to let you know that I raced the new Paketa in Golden this morning at the Tokyo Joe’s Crit.  I wasn’t originally going to race the new bike this morning because I have only done 2 training rides on it so far, but I woke up and said what the heck.  Glad I did. The ride is so smooth and it is much stiffer than my older model Trek carbon bike. The power put into the pedals seemed to drive the bike foward easily with little wasted effort, which helped me save energy since I was racing in 2 separate groups this morning, SM4 and 35+ 4’s back to back.  I placed 8th and 6th and while they weren’t W’s, the results weren’t too bad for my third time riding the bike. Thanks for a great product and I look forward to riding my new ‘Rocket’ to better and better results. — Dave

Excellent job in the TTT, I hope you guys had fun out there! — Jim

Thanks for getting the bike dialed in during the build, I haven’t tweeked anything and the fit is dead on.  — Thanks again – Sargent

Hi Dave – Yeah, the bike is good.  I’ve been enjoying riding it.  Built it up with Dura-Ace, Ksyrium SL wheels and an SRM.  Has been great so far (knock on wood).  Total weight is about 17.5 lbs.  Definitely a good ride.  Can tell there’s some road noise absorption, but don’t feel like it’s soft when it comes to putting power to it.  Stiff on one hand, supple on the other – nice combination.  Hope to do the USAFA Road Race this weekend, then use it for the Haystack TTT the following Saturday, then Gila. Raced one of the Stazio crits and the Koppenburg Circuit.  Felt good (the bike and personally).  Hope to continue to improve and have a good outing at Gila.  Sargent and Lee showed off their bikes at last nights team meeting.  Very nice. — Bruce

Lightweight, high performance travel tandem bicycles

NEW! The Paketa D2 and D2r racing travel tandems are equipped with custom made S&S couplings for easy take apart and travel. Now you can ride a lightweight Paketa magnesium racing tandem anywhere in the world!  

The long wait is over: an S&S coupled version of the venerable Paketa magnesium V2 and V2r tandems are now available!! The name derives from the great French “constructeur” take-apart (“Demontable” in French) bikes of the 1940’s-1970’s, including Rene Herse and Alex Singer, from whom the inspiration for the very first Paketa tandem was drawn. We call ours the “Demon2ble,” or “D2” for short. Nothing else comes close.

D2 magnesium travel tandem – racing and recreational performance riding

  • Travel version of our famous V2 racing tandem –
  • Left side transfer drive
  • Custom S&S couplings for easy travel

D2r magnesium travel tandem – high performance racing

  • Travel version of our famous V2r racing tandem –
  • Right side transfer drive
  • Custom S&S couplings for easy travel
  • Super light weight
  • Any road bike 130bcd crank can be used for lighter weight and greater versatility
  • Custom yoke adds stiffness and performance while accommodating right side belt transfer
  • 44/44mm straight headtube allows use of tapered forks and headsets

Working closely with S&S, the team at Paketa have come up with the next logical progression in high-performance tandems, this time aimed squarely at the wanderer in all of us. Even as a daily rider, it’s still head and shoulders above anything else on the market except our own V2/V2r, and if you only have one tandem, this is it. As a travel tandem, it is simply without parallel. The weight difference is about three pounds vs. our industry-leading V2 or V2r design, creating the possibility of a sub-25 lb. travel tandem that packs into regulation-sized airline cases. The design philosophy is simple: no compromise! We’ve stuck with our standard, oversized magnesium tubing to ensure that the all of the stiffness, responsiveness, and exceptionally smooth ride of the V2 is preserved while still keeping the weight low and durability high. In order to realize this, we’ve specified custom-sized titanium S&S couplings, and the engineers at S&S have come through brilliantly with a novel concept aesthetically integrated with the frame profile (shown below) while providing all of the strength and durability S and S is known for.

Because of the innovative “compact open” low-top-tube design, frame sizes become almost irrelevant. Standover height is ample for almost anybody front or rear, and with a 72.5 cm (28.5”) stoker top tube you’ll never hear any complaints of cramped rear quarters. A quality adjustable stoker stem helps to fine tune the fit of the stoker. Our travel tandems are available with custom geometry or in a small, medium, large, and extra-large with different length captains top tubes. Captain’s top tubes are customizeable to the 1/2 centimeter. We can make a suggestion based on your measurements, or you can have us match your existing tandem or single bike. Our standard sizing goes as follows: Small: 54 cm, Medium: 56cm, Large: 58cm, XL: 61cm.

**we do NOT retrofit couplers into existing frames**

What’s old is new again in tandem design

Archibald Sharp’s landmark treatise, Bicycles and Tricycles: An Elementary Treatise on Their Design and Construction, published in 1896, describes various contemporary tandem frame designs, including “no-lateral,” in some detail. For decades, this simple, open-frame architecture prevailed; sometimes with the addition of a triangulated stoker compartment. Around the 1970’s, various permutations with internal reinforcing tubes appeared with names such as mixte, full marathon, double marathon, up-tube (popularized by Fisher), all leading up to the currently popular “direct lateral” approach used by most manufacturers today. So, why would Paketa choose to revert back to a century-old design? To put it simply, the open-frame design was selected because our engineering and frame testing development program have proven it’s the optimal choice for magnesium—even Dr. Sharp couldn’t anticipate that advancement in materials. A comparable-weight magnesium tandem frame with a direct lateral tube would suffer in stiffness, strength, dent/buckling resistance, weight, or some combination of these deleterious effects. Archibald would approve.

Check out the new V2r tandem with a unique frame design that allows the belt transfer drive to mount to the right side of the frame, inboard of the main drive. Paketa tandem bikes is located in Colorado, near Boulder. Check your local dealer, or contact us directly if you don’t have a local Paketa tandem dealer.

The Paketa V2r tandem (patent pending) eliminates all of these problems in one elegant, integrated, and game-changing design. By mounting the transfer drive sprocket on the same crank spider, behind the main drive sprockets in the rear, all of the disadvantages of the conventional left-side-drive design are eliminated. Conventional single-bike cranks can be used for both the captain’s and stoker’s cranks, for starters. This allows the use of almost any crank, including state-of-the-art light weight carbon cranks, of any crank length to suit either rider. Because the bearing and axle bending loads are no higher than on a single bike, there’s no stiffness or durability penalty for using the very lightest single-bike cranks available—note the Zipp™ carbon cranks on the V2r in the photos. The transfer drive (Gates Carbon Drive™ belt system shown) is mounted far inboard on the right side, which also reduces frame bending in the boom tube under hard pedaling. Even all-out sprints by the strongest riders won’t cause frame “whip” and the unpredictable handling that results.
