My trainer and bike are on a yoga mat and my wife complains about a vibration she hears downstairs. The mat is wide enough for the bar at the back of the trainer but the legs at the front are resting on the carpet. Anyone have a solution? I fhought about buying a thicker rubber pad that's wide enough to fit the legs of the trainer. Anyone tried that? Where would I buy such a thing? Lowes/Home Depot?
Some trainers are generally just loud, but placing it on a thick rubber mat may help (you could find those at a hardware store, as you mentioned). However, the vibrations/noise from the trainer could still be loud enough to hear it downstairs. May be worth a try though.
don't forget that you will be transmitting vibrations through the front wheel too.
What worked for me on an apartment floor was 2 x camping mats and a sheet of 1/2" MDF. a trainer on top of 2 comp mats would have been too unstable but the 1/2" mdf sheet spread the load and also spread the vibration.
I painted the MDF to make it a bit more sweat proof and it lasted the year I was in that apartment easy.
