A speed related bounce or shake can be an off balance wheel on cars as well as cycles. My 14 with alloy wheels and bridgestone tires do have stick on weights that can come off individually or all together which will trigger this issue. Just like a car, you would take it to the dealer and have her checked for proper balance, even a slight miss-adjustment can triggger these issues you describe.
