I am looking for a mat to put below my bike trainer, primarily to help absorb vibration and reduce sound. This is not a heavy gym spin bike, it is a rear-wheel bike trainer, so it's relatively light. However, it would be in a fixed location on the mats. Given my priorities (reducing vibration and sound), would you recommend these HD Soft Tiles or should I go with a rubber mat that will hold up better to the trainer sitting on it in the same position? Thanks!

These Premium HD Soft Tiles are great at absorbing noise from all sorts of workout and can be great at dampening sounds from vibrations. Because these tiles are made from high density foam they will indent a bit with heavy equipment. For equipment with a narrower base (like a exercise bike) we would suggest going with a rubber product like the 8mm Strong Rubber Rolls and our 3/8" Heavy Duty Rubber Rolls which will not indent and cause any imbalance while you're on the machine.
