Se der ja. Noen som kan hjemmeleksen sin

Men hvordan fungerer den med alt mikk makket? Ser ut som en slags demper, men den er liksom "låst" av med staget i midten.. Eller?
sakset fra en omtale av Brodies Whippet replica, skrevet av Ryan King og publisert på http://bikeportland.org:
"The Whippet's unique, seven-pivot suspension design was engineered in London by C.M. Linley and J. Biggs to compensate for the unforgiving ride of the solid rubber tires that were standard equipment on bicycles of the time. The key feature of Linley and Biggs' design was the rigid front triangle that prevented the rider's contact points - saddle, handlebars and pedals - from moving relative to one another when the suspension operated.
By all reports, this innovative system did improve the rider's comfort but the un-damped, single spring design was prone to bobbing under power. Combined with the coil-sprung saddle, the Whippet's extra comfort came with a very bouncy ride! When Dunlop's revolutionary pneumatic tire hit the market in 1889, the Whippet became obsolete and faded into obscurity."
