Very uncomfortable if you have been riding it for more than 20 minutes. Since many including myself have been unhappy with the comfort of the seat, may I suggest a new upgraded seat that is actually comfortable? Fun fact, the only people that dont like it are the people who have ridden it and spent in excess of $2000 -3500 to find out that the seat of this bike is complete shit, and that it is WAY too firm. Compared to the rival of this bike, the Crew Dart, it's incomparable when it comes to comfort which is a massive red flag. Go back to the drawing board and design a seat that is comfortable for ALL!!
