Makes the bike rides much more bearable

I am a novice mountain biker so these shorts make my long rides much more bearable.  I'm sure the much more expensive ones are a bit better but these work fine for me.  Fit as expected and seem to be holding up well.  Woukdnt ride without these.

I am a commuting biker in the summer and find myself along busy highways with narrow shoulders and riding my bike through a moderately busy downtown area. Previous to buying this I constantly had fear of not being seen. It felt like any moment I'd have a car/truck on the back tire of my bike. With this on I feel much more visible to motorists and pedestrians. I like that I can strap it on over any clothes I'm wearing and it's lightweight and breathable for summer months. I slapped the smiley face sticker on the back of my helmet to add a bit of reflecting material to contrast its dark color.

Overall so great! My only issues with it are that the fitting seems awkward at times and the vest gets tangled around in my bag between uses.

Feel safer knowing there is something to attract driver's attention while cycling

I put these on my 3 year old son's kick bike and it really helped him feel comfortable riding it.  I did have to drill an extra hole to get it to fit on his bike, and it took some shoving to get the stabilizer u-bars to fit.  He's been using it for weeks now and they haven't bent or slipped once, and they don't squeak or rattle.

I got this for my mountain bike in order to help out with all the bumps.

Ultimate I chose this over the Long Travel one because I heard the long travel feels floaty. With this, you can still fell the bumps, but the bumps aren't quite as bad. You still want to get off the seat for big bumps. I am considering getting a second one for my road bike.

Does make it easier to ride my bike when it is not leaning downward. Its made of hard plastic and supports well.

As I live in an area that presents problems at times for riding my traditional bike, this allows me to get some needed exercise during times when the weather is not friendly.

I love this. I live in Arizona and during the summer it is too hot to ride outside unless I get up ridiculously early. It was incredible noisy at first, but then I discovered trainer tires (which don't have tread), and it changed everything. I can easily watch tv while riding and I don't have to turn it up nearly as high as possible.

Summer trail rides and bike paths are now explorator on bikes! My dog is 97 lbs has been missing out on exercise because I can only take him on walking trails with us. The piece comes all together, there is no guessing on where things go. You simply undo the bolts and fasten it around your bike then tighten again. Definitely make sure it's tight so it doesn't accidentally move while riding.  Now he can really shed some pounds by joining us on more adventures. It was never a thought to try and ride with him, since it would be dangerous for the kids, who already keep my hands full. I figured this would be a great solution. Now, I can ride with both hands in control and my dog can run next to us. I was able to try this at a discount for my honest opinion.

Replaced the original MTB handlebars on a Mongoose Hitch fat bike with these and it makes the ride much more enjoyable for a big older guy.(in case your wondering why chrome instead of black they were both cheaper and quicker to arrive than the black counterpart and they don't look bad on the bike)They seem very sturdy and appear to be able to last the life of the bike.

It works.  75 mile charity bike ride, and I'm glad I slathered this on my nether regions prior to the ride.  Greatly improved ride comfort. I also bought the small single applications packets to reapply mid-ride.  I don't mind the "cooling" sensation.

This stem extender is lightweight and extremely strong. It was simple to install with a basic hex wrench and quickly raised the handlebars of my single speed bike, making it much more comfortable to ride. I'd highly recommend this to anyone who's looking for a simple way to alleviate any lower back pain that might result from odd riding posture due to low handlebars.

Easy and adjustable install for thick handlebars.  Has a nice ring tone that gets attention of other cyclists and pedestrians.

IF YOU ADAPT THIS FOR YOUR BIKE, IT IS WORTH THE TROUBLE. I NOTICE THAT MORE CARS SEE ME!!! TRY IT

I recently re-cycled an old 70's era craptastic Ross ten-speed into a single-speed bike.  I wanted to take advantage of the hills on my way to and from work as kind of enforced exercise. The bike has 27 x 1 1/4 tires on a bigger, heavier than normal frame. The majority of the solutions I found on-line didn't appear to be quite flexible enough to me to be able to fit without a major re-work.  Once I found these I figured my problems were over.

I was correct, these fenders attached easily with an ingenious rubber strap system which will leave no marks once summer rolls back around and I take them off.  They make no noise as I drive over manhole covers and the other little imperfections in the roads.

I live in Seattle and find that these have kept me from getting my back and legs 'over-drenched' on the light rain days.  I still haven't tried them on a downpour day, but then again I might never choose to ride on those days anyway.

Don't have very high expectations of comfort but definitely helps in extending the tolerable time and distance spent cycling from conventional saddles
