whilst bicycle design is being continuously stretched to its limits, rarely do designers stray too far from the traditional three components—frame, wheels, and chain. by forgoing one of those essential elements—the name is a slight giveaway as to which one—the ‘chainless’ bicycle is reinventing the mould of bike design. powered by tungsten steel gears instead of a rusty metal chain, the foldable model offsets the need to routinely tighten a chain, not to mention the problems of broken links, irritating chain skipping sounds, and caught up shoelaces.

created by sean chan, the chainless wants to bring back the excitement of riding a bike. using shimano gear transition, the model is able to work it’s way around tiny corners and sharp turns, even giving the rider the capacity to cycle in a tight, 360 degree circle. by swapping a traditional chain for abrasion and heat-resistant tungsten steel gears alongside full system disk brakes, chainless sacrifices uneccessary parts in favor of increased agility.

the lightweight bike is also available in a foldable version, that can fit into the trunk of any car yet goes from portability to riding mode in less that 15 seconds. the ‘chainless’ uses ‘lock-n-go’ technology, which does exactly what you’d imagine—simply unfold the bike, lock it into place, and you’re good to go. with magnesium allow wheels and and a built-in kickstand, the chainless S1 simply reduces the classic bike to its most essential elements. founder and creator sean chan neatly epitomizes the design, summing up that ’hopping on a chainless bike will give the rider a sense of freedom where other bikes fail to do.’

  • Well done sean chan – the only creative mind in a desert of American trash. If I were to talk to you for an hour you might stop taking this further and start on something even better – one “secret” is wheel size. Another is parallel wheels. You don’t want to arrive and have to “store the bike somewhere”. Smart people arrive and have their own seat below them. But as you are far enough along the track with this invention I don’t want to steal your momentum, I just want people to waken up to the fact that they have been conned for just 150 years – by the auto industry who don’t want to see people running around using human power – and they will pay anything to stop that happening. Musk is allowed to continue because he is also selling crap – the batteries – junk which will burden you all some day. Think beyond, don’t be limited by yanky thinking, keep it up and step one stage further – contact me. https://www.youtube.com/watch?v=5f_B1L_wc1s is where I found your invention and if you read my comment you will see I am for real.
    I am not doing this for money, I am doing it because I see that we are burning the planet and we don’t need to, we need to connect, we need to grasp what is possible and then someone can implement the idea and I can at last go whizzing past the dirtbags, on human power.
