    Prototype Mountain Cycle

    Check out this prototype Mountain Cycle.
    It shares the indestructible front end of the ShockWave 9point5 downhill bike, but uses a lighter and much shorter swingarm to produce a very maneuverable rip-around bike.
    Here's the spec's
    4-1/2" travel
    15-1/4" chainstays (yes, that's right!)
    14-1/4" bb hight
    15" seat tube
    35 lbs built up as shown with all beefy parts.

    As of now, there are no plans to put this into production. This was just an experiment I put together inside the factory. I think it rides great, very flickable, yet not too loopy.

    what do you think?

    Hmm,

    looks very cool The BB height seems a little tall with such low travel, I assume this means not much sag,so...

    Can she rip the DJ's? Looks like she could, but i'd feel a little 'high up' with that BB... I mean I assume only right? But it would seem it would pitch your forward a bit, no? yes?

    Anyaway cool man!

    maaaaan that is sick. you're seriously sooo freaking lucky to work with mountain cycle, definitely got some sweet bikes up there. Only thing I don' like about it is how little travel it had (I know I know it has its reasons but I like my bikes in the 7in range =P)

    Thanks,
    I wanted the bb low, but the head angle would get slacker. This feels great. Lets me wall ride awesome, and I'm no "wall rider". Bunny hops and manuals awesome!
    I wasn't real happy with the seat tube hight of the MC fury, and a short rear end sounded fun. Definitely worlds better than the flexy Heckler that I rode awhile ago.

    All good. I hear rumors of a few companies actually going into prodcution with the same sort of concept, low travel, short chain stay, higher BB FS bikes for DJ/MTX...

    I may be on a proto myself soon, I'll keep ya posted...

    Thanks alot.
    I don't really need a 7" bike. I've got my proto 9point5 for the big rough stuff. The little bike feels great for everything else. It's sweet having two bikes that are drastically different, yet feel the same.

    Mountain Cycle will be at Falls City Saturday. Say hi to Landon, Ryan, or me if you see us.

    Naw, sold it awhile ago. I've got some other stuff though. How 'bout a psylo u-turn?
    You should start riding in the dirt, come join us tomorrow, it's fun.

    Hey I ride the dirt all the time, The snow is just a special winter time rush you should try it what you doing tomorrow? I need to go to universal in the morning for tires and got some other errands but whats up?

    How much for the psylo?
    I dont need much for the ski-bike just a cheap short to mid travel fork I was thinking dc just to prevent bar spins during crashes ( that front ski flayling around is killer)
    but some adjustability would be nice

    Rob's a great guy, good to have him back. Hopefully he'll join us for the ride at Falls City tomorrow.

    I have a 9 point 5 too. It's a good bike. You should get a better camera. Please send more pix on 9point5 with SC fork.

    Brake squat and pedal feedback!!! I can't wait, it feels like 1995 all over again!

    Look at the ST angle, if you try to adjust your saddle so you can climb up a little (freeride) you increase the top tube by about 5 inches, come on now, that was ok like 10 years ago, but not these days. 2" of up and down seatpost adjustment...Impressive. The suspension design is also widely outdated and outclassed by most modern linkage systems (DW link, Maestro, FSR, etc)...

    If that "prototype" has no linkages (like the 9.5 does) you also forgot to mention the severe falling rate.

    The seat is used for grabbing with the knees and is right where it should be for dirt jumping and 4X style "stand and sprint" riding. The seat can be raised seven inches to what is for me, the full extension pedaling and the correct seat position for that. A 15.25" chainstay length could not be reached with a steeper angled seat tube, since the tire would hit.

    The shock location is rising rate, not "severe falling rate", which is funny that you mentioned since frames spec'ed with air shocks often utilize falling rates to combat the natural overly progressive nature of common air shocks.

    Your comments sound as if they come from who spends far too much time on the computer, rather than actual riding.

    This was just a fun bike I threw together to see how it would ride. After a day at Falls City, I found it to be perfect for those downhill jump trails and took my riding to the next level.

    You show a fundamental lack of understanding of single pivot bikes.

    man you act like a tool sometimes. who cares what you know about bike parts? this guy builds a prototype just to have FUN and you bash him. hey twisted nice bike.
    jm you show a fundamental lack of class.

    Nope, it's not. The only things you can get from a single pivot are disgressive, regressive, and almost linear. The top and bottom are both falling rates, the middle is almost linear, but it is also falling rate. The reason for this is that the rear shock mounts on the rear triangle are never moving directly towards the shock, and as you can see, this is a physical impossibliity without linkages. To make it progressive, you have to look at the rear travel as compared to the shock stroke, but since a single pivot will always move a fixed amount of shock stroke for wheel travel, it can never be progressive, again, it is a physical impossiblity.

    Don't sweat it.... The guy likes his invention and it's not going into production. Besides, it's not intended as a trail machine (this is the DH board, isn't it??) so don't expect to see trail-bike like bikes in here.

    TWISTED: Personally... I might not like a thing or two about the bike, but I applaud you for taking your time and effort to experiment.

    Riding a bike is more than linkages, rates and science of materials....

    There are several features that on it that I deem bad for DH or freeride, but you are correct, this is not meant to go into production and it's just for "him", so in that line of thinking it's ok.

    Looks more like a 4X / DJ Machine and looks fine for the purpouse... not good for anything else, IMHO... but I don't work at a bike company (which I'd love to)
