After MANY years of bicycling inactivity, I am going to start again. My rides will be only once or twice a week. I have a 10-year old hybrid bike, in excellent shape (thanks to non-use!). Last summer I did have the bike "tuned up," confirming my opinion that the bike is still in good shape. More than likely, only one of my rides will be solo rides for exercise and solitude. The rest will be leisurely rides with my young daughters (one still uses training wheels). I'm looking to replace the seat, both for comfort reasons and out of concern for any ill effects on sensitive anatomical areas. :b I don't have a fortune to spend, but since it is for comfort and health, am willing to spend a reasonable amount (between $40 and $60). Can anyone recommend a good seat for a hybrid bike? Will I be able to simply buy the seat, or will I need to replace the post as well? Thanks in advance for any info y'all can share.
