Kenda Juggernaut Fat Tire
The fat-tire standard. A 26×4" Juggernaut floats over sand and snow and is the most common replacement tread on fat e-bikes.

The Kenda Juggernaut is the tire that comes on, and replaces, a huge share of fat e-bikes. The 26×4" (and 26×4.5" Sport/Pro) sizes float over soft sand, snow, and trail, and the big air volume soaks up bumps even without suspension.
Pick the standard Juggernaut for value, or the Juggernaut Sport/Pro for a lighter casing and better rolling. Either way it's an easy, well-supported replacement when your stock fat tire wears out.
Where to buy
Two paths — match your spend to the build. Quality picks last longer and come with real support; affordable picks get you rolling for less. Always confirm fitment, voltage, and connectors for your bike first.

Pro tips from our test team
- Drop pressure to ~10–15 psi for max float on sand and snow.
- The Sport/Pro casings roll faster on pavement than the heavy standard.
- Fat tires need fat tubes — buy the matching 4" tube too.
