Could someone who knows describe the design of the rear suspension of Challenge bikes like the Furai, Fujin or Sieran, please.
Ive been looking for ages and cant tell if the frame has a pivot built in to it or if its only the seat which has a pivot and is suspended and the main frame is one piece. I hope thats clear.
Challenge suspension explain?
Re: Challenge suspension explain?
Yes, the swing-arm pivots and compresses the shock against the seat. There's an animated gif of it on the challenge bikes web site, but it's not responding at the moment.

I have the first Hurricane imported into the UK... It is an elastomer suspension

Re: Challenge suspension explain?
Ok thanks upwrong that makes sense.
Re: Challenge suspension explain?
I've never ridden (or seen) one, but that suspension shock seems in precisely the wrong orientation: will every pedal stroke not contribute to compressing the shock? Could it make for a bouncy rear on steep climbs? The shock on my Fuego is pretty much perpendicular to the chain run.
Re: Challenge suspension explain?
Suspension element location is fairly irrelevant (except for exposure to the elements and internal damping circuits), IMHO. It's the relation of the chain to the rear suspension main pivot point that counts. See online for discussions about virtual pivot point suspensions, for example.hercule wrote:I've never ridden (or seen) one, but that suspension shock seems in precisely the wrong orientation: will every pedal stroke not contribute to compressing the shock?

And depends on the linkages as well, it’s fairly easy to construct a suspension geometry with the shock in any direction you like. It doesn’t change the behaviour of the suspension, just thenpackaging.
A shortcut has to be a challenge, otherwise it would just be the way. No situation is so dire that panic cannot make it worse.
There are two kinds of people in this world: those can extrapolate from incomplete data.

Re: Challenge suspension explain?
Yes, of course, wasn’t thinking it through... looks like the chain passes though the centre line of the pivot so effects should be minimal. By contrast the chain runs substantially below the pivot on my BikeE AT and mashing the pedals can make for a pogoing experience!
