Homemade DH Bike

 Are you kidding Alex? What do you weigh? 95# soaking wet? C'mon man, you aren't wrecking this or any other bike. What is forrest terrain? It's an 8"+ travel DH bike...

It's a nice design based on other jackshaft frames that have been proven to work. Its cool that the builder designed and built it. Hopefully we'll see some videos of it in action soon.

 I'll have to post a video of me taking it off a 30 ft. step down... got find it in my library.
Alex: unless you weigh 300 pounds and your hucking it off a roof to flat ground; it won't break.
I engineered all of the components to withstand a 10ft drop to flat with a 200 lb rider and a factor of safety of 1.5. I have abused the hell out of it at Northstar, Pacifica, etc. and have had no problems at all! Remember, it's made of STEEL!
Thanks for the comments, they're titillating.

 For some reason I thought the rear drop suspension came to close for comfort when it comes to getting through large techy rock gardens. There has been some incidents where I have seen rear suspended bikes, partically within a verticaly rear suspended bikes (Sunday) get there frame and shock components smashed against rocks because of the longer travel for a shorter frame and the fact that there suspension is riding so low to the ground.. Basically saying the geometry of the bike, which appears to be a much shorter frame and the rear shock that travels so low to the ground would be more prone to being bashed by a rock rather than say the demo 8 or tr450 that ride with a horizontally aligned shock on a longer frame.. However I could be wrong, I would take your facts over mine any day..

Not at all saying in any way whatsoever that this bikes geometry or whatever is off.. It looks like a fantastic bike..

 Alex i dot think you really know what you are talking about are you saying that the position of the shock in the frame affects the way a bike will handle a rock garden?
well that is not the case it is all to do with the leverage ratios on the shock (which can be altered using linkages) and the rear axle path which determine how the bike handles so the actual position of the shock has little to do with that (apart from weight distribution) and as you can see the shock is well protected by the downtube. Take a look at the old glory frames

their suspension system actually takes the shock through the downtube and they are not supposed to damage rear shocks more than any other dh bike.
.
or is it that the idea of the bottom bracket coming closer to the ground when the suspension is compressed will damage the frame as it may get hit by rocks?
in that case every fully suspended mountain bike will have that problem as when the suspension is compressed the bottom bracket will go closer to the ground, without that there is no way to dampen the vertical component of the force caused by the riders weight pushing downwards on impact thus causing a very very rough ride its would feel more like a hardtail without that (also that is generally why the chainring/drivetrain on dh bikes is usually protected by a bashguard/taco device)
.

and i wouldn't say this is a particularly short frame it actually looks like a rather long wheelbase bike to me and the shear amount of rearward displacement in the rear axle path means it should be a very smooth ride especially over rock gardens where there will be allot of square edge hits
kudos to the designer/builder that is a damn nice bike i like the way it ramps up the ratio at the end of the stroke
.
Do i spy an adapted kona DOPE brake kit to fit the frame? or did you machine your own?
