I just recently started riding my new huge bike beach cruiser and this fits perfectly on its big seat. My bum bum was really sore after the first few rides to the point it hurt to sit down. I stop riding for a day or 2 until this came in the mail. Now this makes a HUGE difference BUT it doesn’t TOTALLY TAKE AWAY ALL THE DISCOMFORT! You will still a slight discomfort until you bum get use to bike riding. But I wouldn’t ride a bike without this padding! It does the job well and made bike riding a little more easier to enjoy!
