Schwalbe Kojak Tire

The Kojak is designed specifically for pavement and urban environments. Its slick tread pattern offers excellent speed on smooth surfaces, but it lacks the grip and stability needed for loose gravel, dirt, or off-road trails.

RaceGuard is a double layer of nylon fabric that provides a robust defense against flats without adding excessive weight. It keeps the tire feeling supple and fast-rolling, unlike heavier, thicker puncture-resistant casings that can feel stiff or sluggish.

No, this specific version of the Kojak is not rated for e-bike use. It is optimized for standard, human-powered bicycles where weight and agility are the primary concerns.

You should use a standard clincher inner tube sized for 20-inch wheels with a width range that accommodates 1.35 inches (35mm). Ensure the valve type—Presta or Schrader—matches the hole in your wheel rim.

Rigid bead tires can be slightly more challenging to mount than folding tires because the wire bead does not stretch. However, once you get the technique of seating the bead into the center channel of the rim, it should fit securely and safely.
