I'm at a total loss at to how that rear suspension works.

Got any details about this? Looks like the change in FC under compression would be enormous.

Put an Orange sticker on it and you'd flog loads of 'em... 😉

Sorry, meant to include the link.

It's a 6" travel steel singlespeed. I can't get past the stem myself.

That bike needs a lefty to complete the look.

Reminds me of a Cane Creek Thudbuster.

URT is a very lame/ easy solution to the issues of full suspension and single speed. weird parallel linkage to compensate for the fact that mountain biking involves wanting suspension to work when you're stood up which URT doesn't. must be flexy as hell.
interesting to hear how it rides though.

yeah looks like a type of URT, which means it doesn't work if you're on the pedals..

edit: guy above posted same thing.

Looks cool, 'pivot' behind the BB initially so that's the usual URT un-reponsiveness nulled, then around the BB in the mid stroke to make it pedal reasonably well, then right foreward at the end to make it stiff.

Reading the interview it sounds like there's no downsides really, mean's it'll get more regressive/linear the less weight you put on the pedals, so you get the progressiveness for jumps/drops/downhill whilst stood up and regressive suspension whilst seated to give loads of grip whilst climbing.

It's certainly prettier than a lot of peoples bikes on here.

Top half looks a bit like the failed Marin Alchemy...the lower half I'm not sure how it looks...got to be fun to ride though...surely?

how can that pivot behind bb. and the bar/stem?

You can figure out the 'instant canter', 'virtual pivot' or whatever you want to call it by looking at the linkages, the point at which an imaginary line intersects them is the 'pivot'.

So if you look at the links and imagine the rear one controlling the front/rear position of the pivot and the front one controlling it's height and you'll get a vague indication of how it'll work. Starting behind the BB, then at soem point they'll both point at it, then forewards.

maybe, but your weight is still on the unsuspended part of the frame. so unless i'm missing something, however it pivots, it still won't work?

I'm not convinced, I can't see how it will get away from the normal issues of a unified rear triangle often enough, especially when pedalling - there will only be a small window where the virtual pivot point is favourable for responsiveness.

they tried this with the Mongoose full sussers and it just doesn't work well enough - you can't pedal through rough stuff as the suspension just locks up.

That is exactly as ugly as I like my bikes to be.

That's as maybe Northwind but presumably you do it on purpose.

That bike sets a new benchmark in hideosity (new word possibly but apt) 8)

The virtual pivot point at the bottom bracket I can understand, the stem and bar combo however baffles me.

as above, I can see how sat down, the wheel moves as if it had a pivot at the bb (like the concentric bb pivot on a kona A, DMR bolt etc.) This means you do indeed experience your pedals getting closer to the floor under compression of the rear shock as you do with other designs, and feeling as though the rear wheel is moving in order to 'suspend' the rest of the bike. (including the bb/pedals)

What I can't understand is this: if there is a pivot between the seat and the bb, and no pivot between the bb and the rear axle, will the bike not behave completely differently when you are sat down or stood up? Surely it doesn't matter about a clever axle path and virtual pivot point, if depending on whether you are stood up or sat down, the weight/force of the rider that is not held by the handlebar/front of the bike shifts between two completely different areas of the frame, which are either side of the shock and pivots.

I am sure there must be an explanation for this: you'd never get a bike this far through production otherwise, but the 2 second video of the vitrual pivot point doesn't really explain why this will not ride much more like a URT than a 'normally' suspended bicycle. Hopefully they can give us a bit more science!

Its different. I like it.

Although, the reason why most suspension bikes are similar these days is theyve almost sussed it, so why change it too much

Pun intended.

It's an overgrown Thudbuster for sure! (does anyone know what it is?) 😆 I don't think the frame looks so bad, interesting even. But that hidious bar/stem combo needs to go.
