    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!

    But the people buying their bikes don't.

    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.
