I Need a Replacement Tube for My Zulu Series Bike

If your child’s Zulu Series bike (Zulu One, Zulu Two, Zulu Three, Zulu Four or Zulu Five) has a flat tire or a tube that won’t hold air, don’t worry — we’ve got you covered.

Zulu bikes use rims drilled for Presta valves, which are narrower than the valves found on many common bike tubes. Most tubes you’ll find at big box stores are designed for Schrader valves, which are wider and won’t fit through the Presta-sized valve hole in the rim. Attempting to force a Schrader valve through the rim can damage both the valve and the wheel.

We carry the exact replacement tubes with the correct valve type and sizing for all Zulu Series bikes.

• Always check the inside of the tire for debris like thorns or glass before installing a new tube.

• Inflate the new tube slightly before installing it to reduce the risk of pinching.

• If you're unfamiliar with Presta valves, this guide shows how to use and inflate them properly.
