Slime10003 Bike Tube Puncture Repair Sealant, Prevent and Repair, suitable for all Bicycles, Non-Toxic, Eco-Friendly, 8oz bottle

This slime worked out great for my EV bike! I had a small hole in the tire, and after adding the slime, it sealed up quickly and held strong. The tire’s been holding air with no issues ever since.It was easy to apply and saved me the hassle of replacing or patching the tube manually. Definitely a great solution for small punctures.Highly recommend keeping a bottle on hand if you ride often—it really works!

Great for preventing and repairing small leaks. Easy to use.

Works perfectly to prevent and repair small punctures. I use it on my city bike and haven’t had any more issues with thorns or glass since applying it. It’s easy to use, non-toxic, and cleans up with water. The bottle even comes with a valve core removal tool, which is super handy. Highly recommended for any cyclist looking to avoid surprises on the road

I’ve used Slime products for years, and the sealant itself is great ,it does exactly what it’s supposed to do. Once in the tube, it seals up small punctures quickly, and it’s saved me from being stranded more than once. For that, it earns a solid four stars.Now for the gripe ,the stem removal tool that comes with the bottle is laughably bad. It’s just a thin plastic cap with two small notches that are supposed to grip the valve core. In reality, it either slips right off, barely engages, or strips the edges of the valve. On my first try, I couldn’t get enough torque to even loosen the stem, and the tool flexed like it was about to snap in half. I eventually had to dig out my separate metal valve core remover to finish the job.If you’re buying this, I strongly recommend having a proper metal valve tool on hand, because the included one is more of a decoration than a functional part of the kit. The sealant is worth it , just don’t expect the stem remover to actually help you.

Used this to repair a slow leak in my son’s BMX tire — worked like a charm. Easy to apply and sealed the puncture right away. He’s back to riding with no issues. Great product to keep on hand for quick bike fixes!

EDIT: so I had to read the instructions online because what's on the bottle is useless. For an 8-oz bottle it does not have enough space to have directions with a picture that mean anything. When I found them online I learned something new. I didn't know that a basic tube for a bicycle had a valve core. In the 30 some odd years that I have been fixing bikes I have never known this. It would be nice if this was emphasized on the packaging rather than showing a generic twist and turn with a couple of arrows that pretty much don't show what you're taking out of the tire. It would have saved me a whole lot of trouble. Upped the review to five stars because it literally does work almost instantly and I had no trouble getting home after only a few minutes of spinning the tire and letting it sit. Really is quite an awesome formula and I don't know why I didn't know about this earlier.Completely useless. Unless I'm missing something and they're supposed to be more to the so-called "tool"other than it being just a cap, then it is useless. For one if it's supposed to be a tool then why is it sealed off at one end? How is the slime supposed to pass through? Can't just use the tube because there's no pressure on the valve to let air through. And if these are made for only valve stem tubes, it should be specifically listed on the product description and on the bottle. Now that I actually need to use it I can't. So I have to walk a mile and a half with my bike in hand, all the way to my job. Thank you for probably being one of the most undependable pieces of equipment I have bought for my bike. I am genuinely ticked off.

This product works well.I wish the price was a little lower. Instructions says to use about half the bottle for one tube.

Worked like a charm! Only bad thing is that it is very hard to read to get accurate measurements.I see other reviews where they say it doesn't work and it makes me wonder if they actually put it in properly. Valve stem positioned in the top, slightly offset. After it is put in, Schrader valve installed and filled with air then you want to rotate the tire good. Going for a ride is the best way but you can also do it on a stand, with the bike upside down on the ground or any other way to get the tire in the air. You can use the pedals for the rear but for the front you have to spin it with your hands like crazy. You want to make sure it gets evenly distributed through the tube so just doing it a few rotations isn't going to work, do it for a bit.I had a flat from a thorn and used this. When I first did it, I only rotated it by hand for a little bit. Went out to check on it a few minutes later and it had dropped half the pressure. So I aired it up again and took it for a few fast laps up and down the road then let it sit. Came back out about an hour or so later with 0 pressure drop.
