Question: Will the easyseat ii fit on a Diamondback Fitness 510lc stationary bilke
Document: Hadn't seen any reviews as to the use on a stationary bike. I had another seat which did not work very well..Easyseat II is really great. You  have to take some time to get your adjustments for both width and angle right but when you get it it really is a comfortable seat. Both myself and my wife use it and like it much better than any other seat we've ever used on a bike. The exercise bike I'm using it on is a Schwinn Airdyne.
I also ordered the gel seat covers for this, for extra cush. (http://www.bicycleseats.org/easyseat-gel-covers.htm)  Very comfy!
If you're considering a horn-less type of seat, the extra cost for the Easyseat II is well worth it in my opinion. I don't think I'll ever go back to a standard bike seat!
I had originally planned to buy the Easyseat I because of the lower price, but the Hobson site itself said the Easyseat II was re-engineered to move less and had an easy to use width adjustment. So, while I suspect the I was just fine, the II has been great.
The bike seat is a great seat, but due to operator error (that would be me) I had the mounting post on  the bike  incorrectly inserted, so it didn't work, so I sent it back and the folks sent me a different one. I actually think it this one (Hobson Easyseat 11) would have worked if I hadn't screwed up the mounting.
I have a Hobson Easy seat 1. I always had a hard ride with it and the seat adjustment did not always stay in the position you adjusted it to.The Hobson Easyseat 2 Saddle has a firm ride which becomes hard for me after 20 minutes of riding. Are there any seat pads that I may use with this style bicycle seat?
Purchased the seat for my wife, who has had poor results in finding a bike seat that produced the comfort she desired in riding her bike. Thefirst time she took a test-ride, she was thrilled with the seat. As a result I tried it, and purchased a second Hobson Easyseat II...it is great and have recommended it to others. A great product - thanks!
The down side of the original Easyseat was that the pads are a little longer and have less padding, so after a while (20 miles), the pads would dig into the back of my thighs and it became uncomfortable to sit on. I decided to spend the money and upgrade to the Easyseat II. The pads are shorter and the Easyseat II has a considerable more amount of padding, so the problems I had with the original Easyseat are no more.
I was not sure if I should pay the extra $ and go for Easyseat II instead of Easyseat I so I went for version I. I liked the concept very much, it works. I was finally able to bike as much as wanted. The only issue was that the seat was a little hard and also the mechanism to adjust the width is very poorly designed.
I purchased a lightly used original Hobson Easyseat last year on eBay because I wasn't sure if I would like this type of seat, so I didn't want to invest a lot of money in case I didn't like it. I ride a Trek 7300 hybrid bike and the original seat that came on it, was causing numbness in a place guys don't really want numbness.
