Berk has built one of the world’s lightest road bikes that, unlike many featherweight bikes, gives up little in terms of usability. The Slovenian brand has exclusively shared details with BikeRadar on how it created this mind-blowing 3.9kg road bike.
The bike was intended as an in-house project to test the limits of what Berk can produce. The result is a sub-4kg bike that can be confidently ridden daily.
That last point is the key one – according to the Slovenian brand, it would be relatively easy to produce a considerably lighter bike but the brand’s mission is to build truly “lightweight yet reliable parts”.
Berk also wanted to illustrate that, while the rest of the industry has been focussed on advancements in aero and disc-brake technology, there are still significant advancements to be made, and public interest, in lightweight technology.
We can’t help but agree – aero may be fast but there’s little that stirs our weight weenie loins quite as much as the sight of a true featherweight build. Anyone who’s tuned in to BikeRadar’s Hill Climb Diaries will know as much.

I am so sorry guys :(. I was looking really hard at the thumbnail and I think I broke the frame. What was the maximum rider weight limit again ?
I bet that bike is expensive
As durable as a salad on the road?
I wana see the Bike Not this Guy's Ugly Mug!! 😈
Affordable to buy one day? I don't think so. Or maybe a less expensive version for the buyers
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍💪💪💪🚴💤💥⚡✨⚓👏😍🙏
Before I set off, I always find that a haircut, shave and a piss as well as only wearing a jock strap really lighten my Rayleigh Chopper. If I’m going for a really serious ride out, I remove the tyres, brakes, seat and handle bar grips-goes like a rocket!
The chain must weigh the bike down somewhat.. maybe a belt system could reduce the weight even further?
These builds serve no other purpose than flexing. That's an unusable bike, both in terms of maximum rider weight, and long term reliability (assuming you're light enough to actually ride it)
Great when I can have one I'll be in a wheelchair..great…
De que esta hecha de telaraña???
Made out of tissue paper, and no bar tape? Who's going to ride it? Totally impractical
The question everyone is raging for is… Where to buy a similar variant of bicycle!!!!
Wouldn't be surprised if it all turned out to be April's Fool's Day "news"!
Anything about the cost?
Never ever trying to bunnyhop with this bike.
I’d love to do some miles on it
This sub 4.0kg bike is gonna cost over $20,000.
That will ride like a bag of sugar sitting on a noodle.
Belt driver would make it lighter.
For reference, if any of you watching this are parents, remember when you gave birth to your child, yep, thats how heavy this is
How far can you throw it? Great Olympic sport
Imagine taking a dump heavier than your bike
My brake blocks weigh more! I ride a pure steel Thorn Audax. It's 12.5 kilos lol.
No footage of it actually riding, it disintegrated from the sunlight pressure first time they took it outside.
I love it! I'm a proud weight weenie. I love stealthy blacked out bikes and the best thing, no logos !!! I want this.
And the first pot hole you hit, your spine shatters! L5 L3 now titanium.
At last a manufacturer who ignores the UCI! Well done Berk. When will more bike manufactures start to make what consumers want rather than what the UCI let them make??
theres no footage of any of these ultralight weight bikes being used
I can i do and i want one or a couple money is not a problem but im 6.6 so i neeed oneeee
Max rider weight limit: 45kg
We once made the bike to fit the rider 😄..!..now it seems well soon creat a rider to fit the bike 🤔
Great size
What is Slovenia? You mean Slovakia?
Lástima que no esté en español..
Dear heavens why would they put a second chainring on it?
I'm 198lbs so I'd be nervous even trying to ride a bike at the UCI limit, much less this. I've got 158 grams to lose and mine will be under the 16 lb mark, but even then I'm a bit nervous for longevity. Love seeing what's possible though.
… i just made a cup of coffee that weighs 10% of this
The chair is too high.
Wonderfull
my road bike weight only 3kg lighter then that
The chain stuff could be lighter for sure.
piece of advice, maybe you can educate yourself on how to pronounce certain names before recording a video
