Heavy Duty EBike Tube, 20x4.0-4.5", SV 35mm

BikeTube Heavy Duty EBike Tube, 20x4.0-4.5", SV 35mm is built to handle the higher demands of electric bikes while delivering a smoother, more efficient ride. Designed from double-thickness TPU, this tube offers exceptional durability and puncture resistance without the added weight of traditional butyl tubes.

Weighing over a pound less than standard options, it helps reduce rotational mass for better acceleration and handling—especially important for heavier e-bike setups. The advanced TPU construction also improves air retention, meaning fewer top-offs and more time riding. With 50% more strength than standard butyl tubes, this tube stands up to the extra torque and load that e-bikes generate.

Each tube includes two alcohol prep pads and two patches for convenient on-the-go maintenance.
