Looks like a great modification!The rod holding the seat is a awefull design for this class of bike. I had to heat it and chill it to shrink the material to get the rod loose and move by force. Looks like Peloton doesn’t want you to adjust any at all.
After the seat adjustment and the adding the handle bar adjuster, the bike feels like a keeper, with no strain on my shoulders or back any more.
You have to adjust it. No bike fits all. Peloton should have sliding rail for both handle bar and seat.
