Kolelinia / Martin Angelov

Martin Angelov shared his funky concept for a new urban way of transportation dubbed “” with us .  proposes that we ride our bicycles on a steel wire as a new type of bicycle lane.  The idea was awarded first for the international “Line of Site” competition.

More about Kolelinia after the break.

“The first crazy idea which came to my mind was to make flying bicycle-lanes, using steel wire, something like ski lift but working on the opposite principle in which the wire is static and it doesn’t need electricity,” explained Angelov, who presented a more developed version of Kolelinia on Sofia’s TEDX conference a few days ago.

Working off the idea that transportation has to “not only be a transport, it has to be an experience,” Angelov has turned an initial idea into a developed possibility (especially with the addition of his safety features).   Angelov’s ideas make us question whether it is possible to achieve a completely new level of transportation with minimum resources.

    I’m pretty sure a lot of bikers will feel uneasy biking on a thin area of metal, suspended over moving traffic…

    But great idea to not use (more) electricity for transportation purposes.

    People would be hanging from the safety harnesses constantly causing all kinds of traffic jambs. I just don’t see how this would facilitate balance on a bike.

    i don’t think this will work out in any way….

    slow cyclists….fastcyclist….people falling down and hanging from the safety wire….

    and what exactly is the advantage over riding your bike on the ground which does not need any ressources either?

      Of course this line doesn’t duplicate the existing biking areas. This is only for problematic, heavy traffic zones or places where is not possible to exist normal bicycle-lanes. Kolelinia can be only a bridge or a longer line.

        Then why not just build a regular bridge instead? I think that you’re wasting your time…

    i got an idea
    you know what is also a verry cheap, ecological and funky way of traveling…..


    : running.

    Usain Bolt can run 48 km/h, with a little practice we could all improve our speed.

    I think part of the joy of riding a bicycle is the flexibility of going, stopping and parking anywhere you like. This design strongly restricts that freedom.

    This is a great concept. It’s not completely resolved sure, but it’s demonstrates creatively rethinking a problem. If people continue to be so averse to even considering new ideas we’re not going to be solving any of the world’s problems any time soon.

    (Personally I’d feel safer on this than in one of London’s current bike lanes)

    Absolutely agree with previous comment. I think that the idea is great! It gives new observation points, it is very witty and solves many problems, but it needs a few more thinking to make it safer and easier to use. And I think that using this type of lanes might be very usefull in Moscow, with it’s awfull traffic and crazy drivers.

    Hello everyone, thank you for you comments! This is a provocative proposal and I am glad that I made you think about it. For now, I think that the most realistic application of kolelinia is a special designed touristic line somewhere in the centre of a city or a extreme sport in the nature. Now I work on the next level for developing the idea…

      I like the fact that you were able to put something up that provoked so much response ….. getting people to think of something that is not so familiar, getting some kind fo response, is a good sign.

    a tube like, lightweight steel structure that can allow at least 2 bike lanes would be better. elevated bicyle highways can be built, they can even be enclosed / operable. (much like those highways in minority report) cities that consider monorail systems, motor expressways, etc, should look into options like this.

    Maybe as “paper” architecture this has some merit.

    But I can’t help but think that in practice this would be one of the dumbest ideas ever proposed by an architect. People are loathe to change their behavior and expecting them to give up their freedom on a bicycle for the novel experience of riding on a tightrope is destined to be a popular failure & a total waste of public resources.

    Wil Bruder used to say that a trash bin was the most important tool in an architect’s office. With that in mind, do yourself a favor: crumple this up and toss it.

        Thank you for the selective cropping when quoting me. That really helps.

        And no offense, but I doubt that you are smart enough to come up with an even dumber idea.

      • Thumb up Thumb down 0


        Although I do think it has no merit in a city as actual transportation, it could be fun in a park.

    It’s funny that on your montage the cyclist is using a bike whose handlebars wouldn’t fit into your ‘personal safety device’.

    At least, he’s giving us solutions.

    I think it is a great idea, maybe for the rest of the people it is not, but like i just said, he’s doing something, and we are not.

    Keep it up, i know that with a little of work this will be a great solution.

  13. Thumb up Thumb down 0

    Some concerns mentioned above are definitely relevant, but I think it’s a creative idea for starters. Great ideas began with absurdity! Keep it up… =)

    why is archdaily so full of haters? open your eyes: this is not a proposal to replace bike lanes. this is a proposal to provide bicycle connections in areas where other options are not applicable. it clearly has lots of restrictions and provides much less freedom than you get used to on your bike. but it does provide a solution for many conditions where bike riding was unimaginable before. that’s why i think this is an outstanding initiative, no matter how resolved it is.

    Well it’s bold, but it seems like you’re informed by fear of riding in the streets. Do you ride a bike? This would take all of the fun and interaction out of riding a bike.

    What if I want to stop for a coffee? Oh, and no more smiles from pedestrians and motorists.

  16. Thumb up Thumb down 0

    It seems that this, while a novel idea, would be strongly based in the science of movies where the way these systems would interact with existing buildings is not explained and would most likely be impossibly complex, particularly the way that riders would enter/exit such a system as well as instances such as differing speeds. Obviously traditional rail systems require a great deal of coordination where the average user(as demonstrated by automobile drivers) are for the most part unable to operate in something that would require so many constants in the equation that it would fail. I do however think the suspension system has a lot of merit due to massive congestion on the ground level of most urban areas. Perhaps an examination of a lighter gauge tubular steel structure to support both bicycle and pedestrian travel would be more approachable?

    I think its a stunning idea, and probably up there with bungee jumping and zip lines, only alpha personalities need apply. That said why not make the path wider more of a flat bottom U; have concession stands on the occasional pole, maybe a stopping off point with seating and a bar, lets go Blade Runner/Fifth Element all the way…

    I would try it. I think you could harness each persons energy through the wire connections and distribute it to the whole. No slow riders that way, unless everyone is lazy. I couldn’t tell if that was in your drawings.
