Question: will this fit on stationary exercise bikes?
Document: This is a comfy bike seat cover, but it did NOT fit the Marcy PL-43211 upright stationary bike that I bought it for.
Gave this 3 stars as it seemed like it would provide good padding but it was too small to fit over the seat of the stationary bike I had purchased
This will not fit a Schwinn exercise bicycle, and I saw mixed reviews to that effect, so being optimistic I tried, but there was no way to get it to fit. May work for a bike, but not an exercise bike.
I purchased this seat to go with an exercise bicycle. Amazon had it listed as an item to purchase with the exercise bike, but I had already purchased the bike so I ordered only the seat from Amazon. It was at least 4 inches too narrow to fit on the seat of the exercise bike.
Just an FYI, it does not fit the Schwinn 150 Upright Exercise Bike. Found that out too late to return. Oh well, it didn't cost too much. But, a bit of a disappointment. Doesn't seem stable enough to put on my mountain bike, so likely a garage sale item in the future. Probably shouldn't list this next to the exercise bike as an accessory if it doesn't actually fit it.
There are several Schwinn exercise bike models that use the double-wide seat for comfort, and although this one appears to be extra wide it will NOT fit many of those models (particularly the 4-5 year old models by Schwinn that relied on the wider designs).Make sure you measure and triple-check the specifications, the one I received was slightly smaller in width than what is listed in the description.
I take indoor cycling classes about 3x a week, and I was getting bruises and sore spots from the seats on the bikes at the gym. I just tried this for the first time this morning and it was GREAT. I was running late to class, and was worried about taking the extra time to get it on the seat, but it just slipped right on and fit perfectly. No sliding or anything.I know my butt will be thankful. I absolutely recommend this for those doing indoor cycling.
This seat cover was way too small for my stationary bike, so I had to return it.
It fits perfectly on my spinning bicycle seat. Very comfortable, easy to use. Great add on for your stationary equipment. For me is a must.
I am very disappointed with this product. I am using it on my stationary spinning bike and it is still hurting my bottom after months of using it.
Answer: yes
