Larger jagged holes are tough to seal because of the large surface area involved, but smaller and more uniform punctures are easily filled with glue and sealed. When exposed to air, it hardens into this nasty, sticky compound that is perfect for sealing holes in bicycle tubes (but a pain to remove when you get it all over your hands).ДЇor this reason, JoeвЂ™s tire sealant is better at sealing smaller, more uniform holes. While Green Slime is a more fibrous sealant which forms a temporary physical blockage, Joes tire sealant is more a rubbery glue-like material. JoeвЂ™s superВ sealant is also a fundamentally different type of sealant. JoeвЂ™s superВ sealant is installed in a similar way to Green Slime, but usually doesnвЂ™t come with the installation tool needed to remove the valve from the valve stem. Bicycle Tire Sealant: JoeвЂ™s SuperВ Sealant The Green Slime will likely hold for a while to get you back safely, but itвЂ™s not meant to be able to drive around on continuously. When you notice youвЂ™ve got a little Green Slime on your tire and see a screw hanging out, itвЂ™s time to head for your garage or local bicycle shop. For this reason, Green Slime is more of a temporary solution. Green Slime makes more of a physical barrier when it plugs a hole, unlike some of the other bicycle tire sealants we will cover next.

From my experience IвЂ™ve found that while Green Slime will usually plug a hole, it will last a matter of days, not weeks or months. The downside of Green Slime is that it isnвЂ™t a very long term fix. IвЂ™m not positive, but I think the fibrous nature of Green Slime helps it seal nonuniform shaped holes better than some of the other products out there. Basically anything that makes a jagged hole has been fairly well sealed by Green Slime in my opinion. IвЂ™ve found Green Slime to be a better bicycle tire sealant for punctures made by odd shaped objects like screws or wood splinters. This can be done either while the tube is installed in the bicycle or before you even use the tube while its still outside of the bike. You simply use the cap to unscrew the valve from inside the valve stem of your bicycle tube, squirt in a liberal amount of slime, then insert and close the valve with the supplied tool again. Most bottles come with a valve removal tool in the cap to make installation easy. The appearance is, well, like what youвЂ™d imagine a product called Green Slime to look like. Green Slime is a fibrous type of sealant, meaning its got lots of little fibers suspended in solution. ItвЂ™s a great all-around tire sealant and works wonders on bicycle tubes. ItвЂ™s not just meant for bicycles either lots of people use it in everything from cars to trailers to ATVS. Green Slime is perhaps the most famous tire sealant. Here I will review three of my favorite bicycle tire sealants so you can see how they might be appropriate for your own electric bicycle.

If (or more likely when) something punctures the tire and tube, the sealant is forced into the hole and plugs it, keeping any more air from escaping.

The sealant automatically spreads out inside the tube to coat the entire outer surface. You simply fill the tube with a measured amount of sealant, re-inflate it and move on.
