  : No, neither the front nor rear of a bike are MacPhersons. A MacPherson strut (as distinct from other struts) defines something about how track control is handled. This is inapplicable to bikes, therefor they're not MacPhersons. : Nor are bikes strut suspensions at all (we need a clear article on strut suspension but the accurate content we have had keeps getting wiped). The rear uses some form of swinging arm so that isn't a strut. The front isn't a strut because that's two coilovers, one each side, and braced at the headstock by the triple tree. The only strut suspension on bikes is that rarity (Cannondale mountain bikes being the only major user, maybe Mike Burroughs customs too) where there is a single-sided telescopic front fork and an overhung stub axle from it.
