This is genius.. No more muddy backpacks or wet jackets..

A bit tricky to fit on some bikes, and requires a small amount of thinking too, so i guess its not everyones cup of tea :D.

Works perfect on all my bikes.

Sadly they are easy to remove, which is what some asshole did. Luckily they are cheap :)
Next one got locked with zip ties...

Highly recommended.

I was really excited when it arrived and tried it out on the same day. Sadly, I can't tell whether it worked or not since I lost it on the very first ride. Big disappointment; ended up completely soaked.

Hi Gabriel,
Sorry for a slow reply! Please contact so we can send you a replacement. Normally it shouldn't fall of so if you could include a sideview of your saddle, we might be able to help you fit it properly.

Good idea, but simply doesn't work. Just got completely soaked on first short urban ride. Really disappointed as I wanted to love it.

Hi Dan,
Sorry to hear that your first experience with Ass Savers wasn't great. Normally there's a reason for why it didn't work out, so please send us an email of your Ass Saver fitted on your bike and we'll try and figure out what went wrong.

A bit late getting to review this but unfortunately was pretty disappointed with the ass saver original. It took quite some time to arrive but not to worry. However, was a cool looking piece of kit easy to fit but doesn't really keep the rain off at all. Perhaps I should have bought the longer or wider version but given that the original didn't work as expected I don't know what difference they would make. I end up with wet thighs now due to the channelling of the mudguard under the seat. Anyway its cheap so no great loss but would have been better using the money for bus fare on the rainy days!

Hi Andrew,
Sorry to hear that you're not happy with the product. Your observation is correct, the Ass Saver does nothing to protect your inner thighs, it only covers your lower back. Maybe the Fendor Bendor is a better match to your needs? Please send an email to and we will help you out.

I bought this, and followed the instructions as to fixing it, but it fell off on the very first ride. Literally about £8 down the drain. :(

I have bought three rear-fit (as it were) of these for my MTB, and front-and-rear for my partner. With a Specialized saddle, it took quite some time to get the Ass-Saver Wide in place, and on oneride it hopped off. Staffan was brilliant in advising how to get round the problem, though for this one I opted to use cable ties - like with the Mudder anyway - to provide extra security. They're very light, and do a great job or avoiding the worst of the mud-streaks up your back. And customer service is absolutely impeccable. Recommended (just take care with the fitmen t and follow the instructions)...

I bought three of these to save on shipping. Fitted easily and saved my ass many times!

Also gave one to a friend, he had the same experience.

Easily fits; City bike, racer, mountain bike

Light and easy to store under my Cannondale MTB seat. It seems like a great idea. However, doesn't work at all. I was excited to use it in the first rain since getting it, but was quickly disappointed. I used on the highway with no wind. My ASS is soaked and dirty. I really wish it worked. I don't want a full fender bolted to my bike.

Jens Kling from Denmark on Jun 21, 2016
I just got my Ass Saver Original for my road bike (Boardman, no unusual saddle ). I specifically went for the Original to be folded under the saddle. So, it fits to my saddle, pretty tight, but that’s not bad, but I cannot fold it! It doesn’t fit under the saddle.
This is very unfortunate, because otherwise I would have gone for the Fendor Bendor Slim or the Ass Saver Extended, to keep it at home until it rains…
Any suggestions?

Hi Jens,
Sorry to hear that you can't fit the Ass Saver to your saddle. Could you please email some photos (sideview) from your saddle with Ass Saver so we can try and figure out how to ASSist you?
Mantas from Vilnius, Lithuania on May 23, 2016
Oh boy, I had trouble fitting this to my bike. It took me like 20minutes (it`s still faster than mounting fenders, but I expected a faster procedure). The problem was long bolts, that hold my saddle to a seatpost, the prefolded front end of ass-saver kept hitting the bolts when I tried to thread the ass-saver between the rails. Anyway, ass-saver mounted and holds there rock solid. After all, I`m glad that its like that, because I was afraid it will fall off during aggressive MTB ride through roots or other gnarly stuff.
