The Twinbow II is an interesting, and beautifully designed, crossbow made by Swiss Crossbow.

It can be cocked in three seconds and fire a bolt at a speed of 370 feet/sec [ I know nothing about crossbows so I am not sure how revolutionary a 3 second cocking action is].

This video demostrates how it works the action works.

Brenzovich are importing the Twinbow but I am not sure who is actually selling it in the US. Arrow In Apple are selling it in Europe for 1449 Euros.

UPDATE: James has written an interesting post on how this crossbow compares to regular crossbows. It is worth reading.

    Oww wow I want one. Its not the fastest crosbow in fps but I think thats the coolest

    Ever played half life1?There was a magazine feed-semi auto like crossbow there,ever saw smt like this,why cant it be done?BTW twinbow logo looks so much like Turkish flag.

    the Chinese developed a magazine-fed repeater crossbow way back in antiquity, but it had backdraws. (meant as a volley weapon against large formations; inaccurate; not very powerful.)

    this thing looks like it could be made fairly impressively powerful, what with all the pulleys and such. i know exactly nothing about crossbows either, but i’d imagine the speed of reloading gets slower the heavier the pull gets; three seconds might be slow overall, but still fast for a crossbow with the power developed.

      Shawn, LOL that is way to cool!

    I would guess the “Twinbow” name comes from the two separate flexing sections. This bow would likely impart less recoil as the unflexing is sideways rather than to the front. You’re moving the quarrel and string with any crossbow. The normal crossbow would also impart rearward motion from the bow going forward. This one would has it sideways, equal to both sides, and therefore canceling out much of that energy.

    Think of it as a step towards a recoilless crossbow.

    Very cool and vaguely familiar. I think this may be the crossbow that Alice uses to shoot the gas station Zombie in ‘Extinction.’ If so, then it’s been bought by someone at least:-)

    IM GONA BUILD A REAPEATING CROSSBOW LIKE CHINESE ONES CALLED CHOKONHUS O SOMIN I HAVE 2 150LB CROSSBOW LIMBS AND I WAS THINKING OF PUTTING 1 LIMB THE TRADISHIONAL WAY BUT NOW I MAY THINK OF A WAY OF USING TWO TO MAKE LESS RECOIL.I WILL PROBABLY USE A MAGAZINE TO HOLD 12 PISTOL CROSSBOW BOLTS BECAUSE THEY ONLY HAVE 2 FLIGHTS, IF I USED THE BOLTS WITH THREE FLIGHS I MIGHT LOSE ACCURACY BUT THEN I WONT BE ABLE TO PUT THEM IN A MAGAZINE SO I WOULD LOSE TIME IN REALOADING.I LOVE MAKING WICKED CROSSBOWS COS THEY ARE TOTALLY WICKED.SOZ ABOUT CAPS I FORGOT. CYA.

  • ioan hill

    hi back agen i remember caps this time. i meant that i would probably lose accuracy with the bolts with only 2 flights, but i would rather use them because i could put them in a magazine and so i wont need to waste time putting bolt on. the twinbow looks like the best crossbow ever made so far, but im planning on making a better one.im 14 years old. i have a tiny workshop full of junk with nothing usefull to make stuff. it isnt really a workshop, just a shed where everyone puts junk in and i use to make stuff.cya again.

  • ioan hill

    i meant that i would lose accuracy if i used bolts with two flights but i wil use them to put in a magazine and save time realoading.

  • ioan hill

    mistake i made 6th line down i would lose accuracy with 2 flights but i wana use magazine and u cant put 3 flights stacked ina bagazine,if u know a way please tell me. bye.

  • ioan hill

    mistake 6th line down i meant other way round.if u can think of a way of putting boltz wiv 3 flightz in a magazine plz tell me.

      Hello,
      It has been done. The Chinese: http://en.wikipedia.org/wiki/Repeating_crossbow

      It seems to me there is no reason why this cannot be done with sheet metal and careful machining – providing once the new bolt is in place the feeder has no contact with any of the firing chain/mechanism. After all, all you have to do is siphon a bit of the power from cocking to let a new bolt from the magazine onto the track, right? And, if you are using the roll-nut mechanism (and I can’t for the life of me think why Swiss Crossbow don’t think they need that but instead have that hilarious claw thingie to hold the string on both sides of the bolt’s nock so the string hits, strikes, the bolt rather than just accelerating it, a no-no) you need the bolt to seat with the impeller, which is indeed a bit tricky, I am finding. I’m also trying to think up other ways to reconfigure what is after all the storing of potential energy in steel – it’s hard to beat this Swiss idea, except if it could go quite a bit faster :D

      P.S. Seeing that totally bogus crossbow on the PC game Half-Life was what inspired me to research and design real crossbows!

    I do not understand English
    Do you do TWINBOW II no matter how much?
    Is TWINBOW II severalkg if I calculate for the power of a common bow?

  • Mac_Trekkie

    Tarkan, the HL1 crossbow was not semi-auto. Instead what the Black Mesa crossbow did was work like a normal one, it just had a magazine on it. To recock the bow, Gordon simply pulled on a convenient handle BM provided for anyone hoping to fire quickly. Like Gordon. Anyways, this is a very interesting crossbow system. Might be useful for shorter draw “pistol-bows.” This is, essentially, a lever action crossbow. I am very interested what kind of draw power this makes when compacted down to, say, a foot-long bow?

    I’ve used a number of crossbows over the years, including the Twinbow. It’s by far the most elegantly designed arrow-flinging device I’ve tried.

    The real beauty of it is that unlike a ‘traditional’ compound bow (which it resembles) is that it has only one, continuous string instead of a string and two separate cable. It also has wheels rather than cams and you can obtain a spring press for it, so home maintenance is a doddle.

    As has been mentioned, it’s about as close as you get to a recoil-free shooting stroke – the outward and opposed limb movements effectively cancel each other out, so the only recoil the user experiences is the ‘equal and opposite reaction’ of the weight of the arrow (and string) as they move forward (at a rather impressive speed …)

    The cocking mechanism is superb, rather like using a ridiculously powerful under-lever airgun. There’s also a device in the trigger which prevents it being pulled when there’s no arrow in position and a palm-lever to help prevent accidental triggering.
    One little quirk – the cock fletching on the arrows needs to be trimmed close to the shaft, to clear the crossed string in the middle.

    All in all, I’d say it’s a very capable hunting tool – quiet, compact, consistent and relatively easy to maintain. Don’t forget that William Tell is a Swiss national hero – it’s about time they were back in charge of crossbow design !

    I AM TRYING TO MAKE UST LIKE THAT WITH HOUSEHOLD ITEMS

    This crossbow is hardcore! Has a mid-evil look and feel to it but with a 21st century power! I love it!

  • jsj

    有没有高手出来说下原理 感觉有一部份拉力 浪费了

  • Darragh

    WHY!!!!

    I’m an engineer and in my spare time I have been thinking up an idea for a new crossbow design. I quickly checked out the different designs out there and found nothing similar to my idea. I started doing the math and design, only to find out just now that someone has already made an almost perfect replica of my idea. Admittedly I didn’t think of the cocking lever (very cool).

    Just goes to show that if you have an idea you better move quickly or someone will get there first!

    I just have to think of something better

    • Owen

      Hey, Dunno if you can see this but I’d be interested in purchasing a crossbow made by you in this style, I cant find a twinbow anywhere so you’re pretty much my last option :3

  • tim

    Holy shit I want this so bad. Looks midevil
