    Not being a dick but what's the point? Seems no different than if I used a suspension seat post on my fs. Plus, the seat tube angle looks like it will change significantly when the upper shock compresses.

    I'm far, far from being an engineer so pardon me if I'm missing the purpose of the design.

    From experience, being around mountain bikes since the start.

    No to be a jerk, but that design is pretty pointless. A solution to a problem that doesn't exist.

    Crazy design! would love to see an actual product, I also love car crash videos and riots.

    I'm no bike designer, but those stays may need some work, it looks to me there is nothing to stop lateral movements around that rear shock - as in the shock is providing structural stability which is a very bad thing. Either throw a link in similar to a santa cruz / intense or make the the rear stays a sold triangle.

    Just my thoughts on it....
    A none HL rear suspension will probably let the bike bob when peddling and your sketch would have a falling rate so effectively the suspension will feel softer the more travel you use up. You are letting the seat bob up and down when peddling too with a suspension that is only really absorbing your body weight and has little movement due to the wheels as your existing suspension should be doing this job anyway. You are adding weight and complexity to a problem which you feel is there having faced it once and admit that it was an accident where you went too fast and had the bike leaning when you landed so even this solution would not have stopped the crash....

    Re: Triple suspension mountain bike.

    There's a reason you haven't seen a design like that before.

    Credit to you for thinking outside the box but its not something I would buy.

    How is this an improvement over just sticking a Cane Creek Thudbuster on any existing FS mountain bike? (which, BTW, basically nobody does because it serves no purpose).
    15mm is a second-best solution to a problem that was already solved.

    1) Terrible idea.

    2) Improve your sketches

    3) If you are interested in building bikes get into mechanical engineering or related.

    Good luck!

    Keep designing and don't let people be ***** to you. To be honest, it's not the best design, but it's great that you're trying. Designs like this have been tried before, but most people realized that riders prefer to have their suspension working when they sit or stand, not just when they sit. Add to that the added weight of a second shock, and you can get a better riding design with less complexity.

    Here are a few similar examples from the past, both worked better when seated vs. standing.

    No "sandwich" - those bikes you are showing are URTs (uniform rear triangle). That's not what the OP is thinking of. His design is more like adding a suspension seatpost to a full suspension design. It's a bad idea, but the best way to do it would be to use one of those carbon beam designs for the seat suspension. (Look up Allsop Softride). Less moving parts that way.

    no, they aren't. URTs are characterized by the crank not being suspended. Both those bikes accomplish something similar to what it looked like the OP was getting at, only using the same shock for both actions (wheel and seat suspension). URTs essentially only worked when the rider was seated.

    It's a fine line, thinking out of the box vs ideas that have been tried and fallen out of favor. As you can see, designs like this have been tried and never gained traction, but then again 29" wheels were tried and the idea discarded in the 80s, long before the current iteration.

    Kudos to you for envisioning something and building it. Go be a mech eng, seems right up your alley.

    As to the design, meh. Why would I want the distance from the seat to the bottom bracket constantly changing? Seems like an incredibly annoying trait. Plus the extra weight and complexity, it's all too much with no improvement imo, in fact quite the opposite of improvement.

    Don't let the jeers stop you though! Builld it, ride it, improve on it and build it again! Through research, trial and error come results and you are building a foundation of knowledge and experience for yourself that will serve you well in the future (I'm assuming you are quite young).

    Yeah, you stand when you go down hills, therefore causing the air shock to be useless. There is no need for the seat shock, and how will it be climbing? Heavy and bobbing the whole way. So you have extra weight and a bad climbing thing for descending with a low travel steel coil shock that can come on Kmart bikes.
    Seriously, rethink that idea.

    So it's "currently being built"?

    Based off of a real design, or just those sketches? Cause it doesn't appear ready to be shipped off to production just yet.

    Unless you're giving the builder a lot of leeway.

    Not ready? What are you talking about? It's even got "Fox" written on the fork and butt-shock.

    If you really want to get into Mountain Bike Design, I applaud your efforts, but this isn't the way to do it. If you really want to design bikes, think critically about what a suspension is supposed to do, and why this does a bad job of it. Read more, sketch less.

    You might have a LAW SUIT on your hands!! thats a blatant rip off of my quintuple suspension design that uses multi angle bump absorption and "shocks and stuff"

    WOW PUNTOS DE COMBUSTIBLE! and $3.89 for 2 gallons of milk is not a half bad price. Milk is one of the few things Costco cannot competitively price. I did buy a new vacuum though. I'll post the receipt when I get a chance.

    yeah not really, research that. it's all a marketing ploy, you gain absolutely nothing from cow milk except way too much of the wrong proteins. not to mention there is a significant amount of puss in there from dirty infected teats, lol

    Other animals will drink breast (human_) milk if you feed it to them, if they had the means to produce it other animals would drink it.


    What is it that you want me to research?

    Milk being good or bad is not the issue. calling somthing wierd is

    we're the only animal that drinks other animals milk (not talking life and death baby animal situations) , and as adults to top it. your original statement sounded like our bodies were designed to accept other animals milk. milk actually pulls calcium from our bodies. its weird b/c we have been brainwashed into thinking that milk does a body good. our bodies have a helluva time processing it

    We are also the only animal that cooks our meat and shits in a toilet/privy. Is that a problem?

    FWIW, all of my dogs or cats would eat dairy if I gave it to them. Of course, they also lick their anuses, and my dog will drink from the toilet, so I'm not about to use other animals as my guide to "normal"

    i do shit in a toilet, but you can have the charred meat and all of its carcinogens. diet is pointless to argue with someone who names themselves after a sauerkraut & pork dish. i don't use other animals as a guide to what is "normal". i've educated myself thats all

    Wow, a proselytizing vegan, I don't know that I've seen this before.

    I suggest starting a thread on this, I think there would be a lot of interest.

    Even better, a condescending, proselytizing, vegan. Now that's REALLY rare.

    Keep going, please.

    And while you are at it, please continue to make unfounded (and mostly incorrect) assumptions about what I do and don't eat, and what I have and have not read.

    Most vegans i run across seem to be self apointed nutrician experts because they read a book printed on hemp paper written by a guru.

    They ignore all reasearch that doesnt support whatever belifes they currently have....

    Vegans are just gun nuts born to differnt parents.

    I was about to disagree with you, but I can't. Gun nut or vegan, just keep it to yourself. Its not wise to advertise the fact or amount of guns you own

    It's not the lifestyle of gun nuts, gun haters, vegans, smokers, ex-smokers, or religious followers that people despise, it's just that nobody likes to be preached to unless they are literally asking to be preached to.

    Being self righteous is not an endearing quality in any person.

    Funny cause I avoid soy due to all the estrogen amongst other things. Nope I'm not a hipster either but I do own multiple guns. Funny how many haters there are.

    Haven't used it, but looking at the link, I imagine that attaching it to your handlebar would require a hefty amount of beefy zip ties. Probably still safer than the crappy iPod headphones I ride with. Plus, on race day you will be faster when you uninstall the 30 lbs of stereo from your ride. Unless you are one of the kool kids blasting trance music at 3am on their onboard speakers during their 24 hour race. If that's you, carry on!

    I'm a big Polk Audio fan, with a 7.1 system in our main entertainment room. But in my den, I have this Soundbar from Polk and have been surprised at how good it is:

    Amazon.com: Polk Audio SurroundBar IHT 6000 Instant Home Theater (Black): Electronics

    The wireless sub is surprisingly good and the bar does a great job at simulating a surround feel.

    In defense of most vegans, they just quietly go about living their lives the way that they want to, they're just not as noticable because they aren't making snarky comments implying that the rest of us are morons for not making the same choices they do.

    It's much easier to notice the ones who are jerks about it, but I think we should be fair and rip on them for being jerks, and not suggest that has anything to do with being vegan. There are plenty of meat and/or dairy eating jerks out there too.

    Why would you try to bring a de-railed train back onto the tracks?

    Back on track. OP, if I were you I'd check Sketchup for your sketches. It's free and you can draw some pretty nice frames in 3d. Here is one that I threw up in about an hour. (The shock you can import from a repository of components). All the angles and dimensions are taken from a mixture of a couple of bikes. I'm by no means an engineer so I have no Idea if the suspension system would work adequately.

    It's easy enough and many places will accept sketchup drawings for CNC work. Not sure how that would work with an entire bike. GL

    unless there is a hidden linkage the swing arm doesnt look like it would compress the shock at all

    Fuglio, help me out. I am trying to gain understanding on rear suspension fundamentals. Is the reason that linkage is required because of the need to change the ratio of shock movement to rear axle path movement? The leverage ratio? A one-to-one direct link such as the one above can't work like so because you would only get like minimal travel, what ever amount your shock stroke is:Am I on track with that. The linkage is needed to be able to change the leverage ratio, right?

    How much travel is that giving you? And whats the size of the shock? I was thinking a link would help compress the shock . Looks like a 5 to 1 compression ratio and only able to use the first inch of a three ininch shock before banging into the down tube as the swing arms path no longer compresses the shock and pulls it out


    So it needs a linkage cause its all jacked up

    Maby a short link at the top shock mount. Try that and see what the leverage ratio looks like. I think if we can get to 1.5 then we can move towards protype mock ups

    Re: Triple suspension mountain bike.

    If you're serious about this you should pick up a mtb modeling software like this one, there may be others:

    http://www.bikechecker.com/

    you should also look at a solid modeling software with finite element analysis capabilities.

    Full suspension sketches without at least some level of engineering aren't worth the paper they're printed on. Its like drawing a new fancy sports car and asking everyone if it will be fast.
