Good quality tire to keep as spares

I recently purchased the Hycline Fat Tire as a replacement for my old electric bike tires, and I must say I'm impressed with their performance. These tires are specifically designed for mountain and snow bikes, and their wide surface area provides exceptional traction on slippery surfaces. The 4.0-inch width is perfect for tackling rough terrain, and the folding design makes it easy to carry them around as backup tires for emergencies.The installation process was straightforward, and I was able to fit the tires on my electric bike without any issues. The build quality of these tires is excellent, and I'm confident that they will last for a long time. I also appreciate the compatibility with a wide range of bikes, which makes them a versatile option for anyone looking to upgrade their tires.Overall, I highly recommend the Hycline Fat Tire to anyone looking for a durable and reliable replacement for their electric bike tires.

So far so good!

Purchased to replace my CST BFT on my Kepler. Mounted with no issues and ride is soft and smooth. Only 50 miles on it so I can't attest to the long term durability. I like that it's 30 TPI and has solid black sidewalls. Decent overall fat tire for $40 price range.

Love the new pattern

My electric bike have fat tires and if they need to be replaced this is what I use. This is the same size as the tires my bikes came with and it’s not difficult to install it. It functions as expected and I haven’t had any issues using it.

Excellent tires for both street and trails...

Perfect riding tires on the street and dirt trails or grass... Replaced my Hycline 20” fat tires and tubes. I did it myself and I’m no mechanic! I’ve put about 100 miles on them. No problems!

What should I consider when choosing bicycle tires?

When selecting bicycle tires, consider the size, tread, width, durability, pressure, weight, and riding style. Choose a tire that fits your bike's wheels, is appropriate for the terrain you'll be riding on, is durable and puncture-resistant, can handle the recommended tire pressure, and matches your riding style.

What size bike tire do I need for my bike?

To determine the size of tire you need for your bike, you can look at the sidewall of your current wheel, which will have the tire size printed on it. The size will typically be expressed as a combination of numbers and letters, such as "700x23c" or "26x2.0". The first number refers to the diameter of the tire, which is measured in millimeters for metric sizes (e.g. 700) or inches for imperial sizes (e.g. 26). The second number refers to the width of the tire, also measured in millimeters or inches. The letter at the end indicates the type of tire (e.g. "c" for clincher)
If you're unsure about what size tires to get or have any doubts about compatibility, you can consult your bike's owner's manual or contact the manufacturer for advice.
