 Thanks brah, my thoughts entirely. I can drop the top tube down way more cause I put everything low down on the frame. I like how the scissor jack prototype came out with the super low frame so I think i will do it on this one as well.

 that is one of the sweetest designs ive ever seen. it compresses the shock from 2 different directions and the wheel path goes up and then out. very nice man. props for this

 like it alot more than the previous one, looks sorta like a commencal in the way the shock is placed but probably with alot better proformance thanks to the added links

 its just been proven how easily people fall into manifacturing gimmics!

 thats a very intresting concept , but the issue will be getting the strength into such a close ratio linkage....

 How do you mean?

 this frame would just snap instantly, for starters the grey link that connects to the shock pushes outward as it comes up , but the wheel wants to push it inwards, its impossable to explain , but this will simply fail!on so many levels. just think about it..... and think about where the force (rear wheel upward force) is being aplied to. the end of a lever efectivly! it wants to piviot around the lower conection! it will snap instantly! also when the frame is bottomed it wants to keep streching the white lower link....redesign before preduction!

 You know I do have a video of me actually riding it and it didnt snap then. I cannot validate any of your concerns with regard to the linkage in any way. The thing works really well.

 you have no vid's of this exact model without alterations to the linkage (that i can find)
  • + 1
 Its really the same linkage as my capstone frame. If you say its impossible to explain then you dont know what youre talking about or its not an issue. This animation is done in SolidWorks. If it were going to bind or break based on simple motion, the interference detection would not allow it to go through all of the travel and thus there would be no video showing it work.

 nice the wheel path is pefectly vertical are you going to beef up the head tube wtih gussets or not ?
  • + 0
 oh yeah i'll definately put a gusset across that junction like on my other bike its just not on there yet. You know, details.

 the wheel path isn't vertical it kicks you backwards

 wouldnt the rearward movement of the swing arm create chain stretch?
  • + 1
 it would if the chain were routed around the cranks at the bb but since it goes around the roller at the top links fixed pivot like on my other bikes and some on the market, there is none. In fact the chain shrinks a little bit.

 lol this one is uper sweet how much rear travel
  • + 0
 this particular rendering has 8.5 inches rear wheel travel but I may bump it down to 7 for a freeride bike.

 sweet you going to make it
  • + 0
 hopefully this winter but definately in the spring for my senior design project. Just need money for materials. Good ole Xmas should come through.

 sweet you going to running triple clamps or singles
  • + 0
 single if its 7 inch triple if its 8.5. Prolly a totem or 66 depending on what I can afford.

 luvin the new desighn mate

 this design is bad ass you should make a low top tube for tricks
  • + 0
 sick man
  • + 0
 is this left side drive?
  • + 0
 The crank is on the left side but the single swingarm is on the right with the chain line to the rear hub. Its less cluttered having it split this way.
