    hello! okay so ive been riding my Sym Jet 4 2010 model to college every day and that involves traveling along mainly 40 mph roads. and something slightly worrying has come up. when i get to around 40 MPH this weird noise comes from under the seat / rear wheel im not exactly sure and it feels like its vibrating. i have no idea what it is! now the bracket that supports the mud guard snapped so i thought it was that hitting the wheel... but there are no signs of wear underneath the mud guard.

    any help would be appreciated :)

    Just check round for any loose bolts etc.

    take the bracket off and check the rear mudguard, i had a same problem, turns out after i changed my tires to some more grippy ones it was catching the side of the mudguard :// because after long periods of driving the tires can expand, just check for anything rubbing or wobbling, take the seat out and have a proper look at everything, maybe the real wheel bearing? im not too sure about them tho
