World’s Lightest Road Bike at 2.7kg

world's lightest road bicycle (15)
This road bike weighs in at 6lbs (2.7kg): Lighter than the laptop you’re probably using right now.

The bike you’re about to see was an idea originally started and created in 2008 by a German guy named Gunter Mai who logged over 20,000km on the machine for a couple years and it weighed at around 3.2kg.  Early in 2011 he parted out the bike and sold each piece individually around the world.  Some of the key parts were bought by some guy in Colorado who commissioned Jason Woznick of Fairwheel Bikes in Tucson, Arizona to create even lighter parts to finish a new build of it.

Every part on the bike is completely custom made and cannot be bought unless you wanted it made specially for you.  Even if you did want it made for you, you would have to contact manufacturers who already make the lightest parts and then ask them to make a custom piece for you that is even lighter.  Woznick guessed that if you tried to recreate the effort put into this bicycle, it would cost you at least $45,000.

As a result, this new machine weighs in at 2.7kg or just about 6.0lbs.  I can’t imagine what it would be like to hold such a large item that weighs two pounds lighter than a gallon of milk, but it must feel like nothing!  Even the carbon fiber used in the wheels isn’t readily available (even if you have the cash for it) as it’s a special grade that was gotten from some Formula One guys.

As a result of some of the custom work, this has allowed manufacturers to push their limits.  Both of the prototype Dash hubs will actually be going into mass production this year, for example.  Anyway, enjoy the pictures as there isn’t quite a bike as exotic as this in all its minimal glory.

To give you an idea of how light this bicycle is relative to other bikes on the road. The bicycle you have probably weighs 20lbs pounds or more.  To be under the 20lb mark, you probably have spent some “serious” money as each pound you shave off below 20lbs becomes exponentially more expensive, to the point where people compare grams of components.  The Union Cycliste Internationale (UCI), which is the governing body for most of the pro races around the world, has a minimum weight limit of 6.8kg (about 15lbs). So when you see those $9,000 bicycles in the Tour De France, they are about three-times heavier than this bicycle. Of course there’s more to a bicycle’s performance than its weight though. A lot of the cost doesn’t go into making them lighter but in making them handle better, be stiffer for efficient power transfer, shift more smoothly, be reliable, have less rolling resistance and most of all to reduce aerodynamic drag. As you ride faster, aerodynamics are much more important than weight so unless your entire race is uphill, weight isn’t that important, but this is pretty amazing stuff anyway, considering it’s three times lighter than the bikes the pro’s ride with.

Enjoyed this post? Hell yea you did! It’s cause BICYCLES ARE THE BOMB!

Don’t you wish commuting by bicycle was more practical though? I know we often struggle with carrying many items and have to limit what we take with us. And if we take a backpack it makes our traps all knotted up and our back sweaty.  The solution? These Ortlieb Pannier Bags. They changed my (cycling) LIFE because it made commuting practical. The way they come on and off the bike is so ridiculously easy.

See for yourself!  Here’s a video of me demonstrating their awesomeness.

    wouldnt a Belt drive and single speed hub make even a little more lighter ?!?

    • http://www.antranik.org/ Antranik

      It absolutely would but then it wouldn’t be considered a road bike.  I suppose the idea was to keep it to something geared so it would still be a typical road bike.  For the record, as someone who owns a road, fixed and mountain bike, my fixed gear is absolutely the most fun thing ever. 😀  Unfortunately nobody understands that until they have one of their own :(

      Likely. The cassette and chain has to be huge percentage of the total weight. However, I wouldn’t underestimate just how difficult it would be to make custom belt sprockets. The current carbon fiber belt drive systems require specially coated aluminum sprockets to prevent the belt from wearing down the teeth. Those “standard” belt sprockets from Trek would probably be too heavy for this bike.

          what max weight the bike can take? surely not the strongest design out there?

      you do understand that 790g  is just the frame weight, right?

  • Bernardo

    That bike weighs as much as my mondraker foxy frame without the shock.

  • Alex

    you guys are not very well informed. Günther’s last evolution step was less than 2,9 Kilos with deep rims. This bike is lighter, no doubt, but that’s just because of the lighter wheelset. In fact, this is just a checkbook built from a guy with too much money.

  • moumen

    where can i buy 1 ? any links ? thnx

  • nick

    take off the brakes and make it single speed

  • Yemi

    very nice looking bike, and agree that unless u are riding uphill endlessly and u weight very little (à là mountain goat) weight is not that much an issue, something else i found out when getting my bike was carbon qualities vary from manufacturer to manufacturer, but by the looks and sounds of this bike the higher quality carbon weave 100% was used. But got to admire the effort put in the creation of this amazing rig.

  • http://maxhodges.com Max Hodges

    James C. Martin, Ph.D., assistant professor in the department of exercise and sport science at the University of Utah provided some interesting calculations that make the cost of weight very clear.

    He posited a 5 kilometer, 7% grade. That’s a good, stiff climb. The legendary Stelvio climb averages 7.5%. He further assumed a rider who can kick out 250 watts. A 160 pound rider will take 19 minutes and 21 seconds to get up the hill. Every 5 pounds added make the trip up the hill take 30 seconds longer.

    That means each added pound adds 6 seconds to the time it takes to get up this hill. That is only 6 seconds on a stiff, 20 minute climb.” (0.005% advantage)

    The performance advantage of a lighter bike is greatest when the hill is steepest. What happens as things flatten out? Then, as the speed of the bike increases, the resistance comes from the wind, tire rolling resistance, bearing drag, etc. and the 0.005% advantages becomes much less significant.

    If you live this bike unattached on the street, it could be blown away by slightest breeze…
